Power Levels Advantium uses power from high-intensity halogen lamps, as well as microwave energy, to cook foods evenly and quickly (average of one-fourth the time of a conventional oven) to seal in moisture and flavor. Power levels are selected with the selector dial and can be adjusted before cooking or during cooking. When using preset menu foods, the power levels are already selected for you. However, power levels can be adjusted when cooking both preset menu food and when manual cooking. Power levels are adjusted independently for the upper halogen lamps (pair), lower halogen lamp (single), and microwave energy. When selecting an upper halogen lamp power level, the power level can only be selected for the pair. You can not select power levels for the upper rear and upper front independently. Power levels of 0 to 10 can be selected for the upper halogen lamps (pair), lower halogen lamp, and microwave energy. The power levels control the percentage of ON time for the upper halogen lamp pair, the lower halogen lamp, and microwave high voltage circuit. The programming on the smart board which controls the upper and lower halogen lamps, as well as the high voltage/magnetron circuits, operates on a duty cycle of 32 seconds. This means the power level you select for each component controls the percentage of ON time during each 32-second period of time. In the following example, the upper halogen lamps would cycle for 80% of each 32-second period, the lower would cycle at 50% of each 32-second period, and the microwave high voltage circuit would be energized for 30% of each 32-second period.

Microwave Energy (M=) Microwave energy is provided by the high voltage/ magnetron circuit and directed via the wave guide directly into the oven cavity. As the food rotates on the oven turntable, microwave energy is evenly distributed to all portions of the food. Select a higher setting to shorten cooking time for dense or heavy foods (example: casseroles, whole chicken). Select a lower setting for delicate foods (example: cakes, breads, souffles) or foods requiring longer cooking times for tender results (example: stew, pot roast). GEA00398 SECONDARY INTERLOCK RELAY MGT TCO (302 /140 F) CAVITY TCO ONE SHOT (302 /140 F) FUSE (20 AMPS) CONTROL BOARD N L1 PRIMARY INTERLOCK HV PRIMARY WINDING (MAGNETRON) Voltage Compensation Note: Voltage compensation only occurs during speedcook operation (preselect menu item). In other words, when cooking with manual cook, voltage compensation does not occur. When using speedcook, you are selecting preselected items from a menu. These items require compensation for accurate and consistent cooking results. Voltage fluctuations in the power lines can cause inconsistencies in cooking. Advantium automatically measures line voltage at the start of each speedcooking selection and adjusts the cooking time to achieve consistent quality results. Line voltage is monitored by the voltage compensation transformer, which is located on the smart board. This transformer monitors the voltage from L2 to neutral. GEA00424 SMART BOARD Voltage Compensation Circuit BN Y The optimal line voltage, where no voltage compensation occurs, is 120 VAC. Above 120 VAC, time is subtracted from the recipe. Below 120 VAC, time is added to the recipe. The amount of voltage compensation required is dependent upon the incoming voltage at the start of the cooking cycle, and the particular speedcooking selection that is chosen. The chart below shows the predicted compensation times based on a 5-minute speedcook selection (such as: Biscuits, Refr; Large; 8 biscuits).

The display will show “OPTIMIZING COOK TIME.” The time will flash and then display the new adjusted time, based on the amount of voltage compensation required. GEA00425 OVEN LOCKED SELECT MUTE TIMER OPTIMIZING COOK TIME 9:55 Voltage compensation only occurs during speedcook operation and only occurs once during the cooking cycle (at initial start of speedcook operation). Upper Halogen Lamp Balance As stated previously, the upper halogen lamps operate together at the same power level. However, in order to provide even (balanced) cooking performance, the upper rear halogen lamp will always cycle at 85% of the upper front halogen lamp. In other words, if the upper halogen lamps are set at power level 10 (U=10), you would expect both elements to operate at 100% of each 32-second duty cycle. Instead, the upper rear halogen will cycle at 85% of power level 10, or

85% of 32 seconds. The upper rear halogen lamp will cycle off just prior to the upper front. Thermal Compensation Note: Thermal compensation only occurs during speedcook operation (preselect menu item). In other words, when cooking with manual cook, thermal compensation does not occur. When using speedcook, you are selecting preselected items from a menu. These items require compensation for accurate and consistent cooking results. When cooking several food items consecutively, the temperature in the oven’s interior can become very hot. The Advantium speedcooking program (smart board) automatically compensates for the increased temperature by adjusting the cooking power levels of the upper and/or lower halogen lamps. This innovative technology gives you oven- quality food with consistent results. GEA00439 Located inside of the oven cavity (upper right rear) is a thermistor. At the start of each new speedcooking operation (just prior to voltage compensation occurring), the cavity thermistor reads the oven cavity temperature. Depending upon the oven cavity temperature and the amount of cooking time selected, the smart board will adjust the power level of the upper and/or the lower halogen lamps to compensate for the additional heat that may already exist in the oven cavity (if previous cooking occurred). GEA00400 1 3 CN6 APPROX. 219 K @ ROOM TEMP. The oven cavity thermistor has a negative temperature coefficient. In other words, as the temperature of the thermistor probe increases, the resistance of the thermistor decreases. This resistance changes rapidly with small changes in temperature. In fact, you can squeeze the thermistor and see the resistance change fairly quickly. At room temperature, the thermistor should read approximately 200K to 250K ohms. Thermal compensation can affect the upper halogen lamps power level, the lower halogen lamp power level, or both the upper and lower halogen power levels simultaneously. Thermal compensation can lower the upper halogen pair by 1, 2, or 3 power levels. The lower halogen lamp can also be reduced by 1, 2, or 3 power levels, but never independently of the top halogen lamp pair. In other words, thermal compensation on the lower lamp will never be greater than the compensation occurring on the top lamps. It is possible, however, to have thermal compensation occurring on the upper halogen lamp pair, but not on the lower lamp. Neither the upper halogen lamp pair nor the lower halogen lamp can be compensated below power levels of 2. In other words, if a power level of 3 is selected for either the upper halogen pair or the lower halogen lamp, then thermal compensation can only reduce the power level by a maximum of 1 power level. Thermal compensation only occurs when oven cavity temperatures are higher than normal from the previous cooking operation. When thermal compensation is required, it will occur immediately upon the start of a new speedcook operation (just prior to voltage compensation occurring) and there will be no indication in the display that thermal compensation has occurred. The amount of thermal compensation (1, 2, or 3 power levels) depends upon the temperature of the oven cavity at the start of the speedcook operation and the amount of time selected. When thermal compensation occurs, it is not possible to see the adjusted power levels in the display. If you were to press the power level pad during a speedcook operation in which thermal compensation occurred, you would not see the adjusted power levels in the display. In fact, what you would see is the original power level setting. However, you can visually see compensation occurring by carefully observing the cycling of the halogen lamps. WARNING: When viewing the halogen lamps, do not stare directly into the face of the door window. View the oven interior from a distance far enough not to cause eye strain.

Thermal Compensation Test To better understand this operation, you can perform the following test (only if the oven cavity is at room temperature). Remove the pan from the oven so you can see both the upper and lower halogen lamps. Select “Speedcook, Meats, Hamburger, 1/2 inch thick, 1-2 patties.” The following will show in the display: GEA00426 OVEN LOCKED SELECT MUTE TIMER ADJUST TIME or START 3:00 U=10 L=10 M=10 Notice that the display shows power levels of 10 for each cooking component. During this test, you will be operating the oven with no load. For this reason, it will be necessary to adjust the microwave power level to zero (M=00). To do this, press the power level button on the control panel. Leave the upper and lower power levels at 10 (U=10, L=10), and adjust the microwave to zero (M=00). GEA00427 OVEN LOCKED SELECT MUTE TIMER Press START to run 3:00 U=10 L=10 M=00 NOTE: Set Microwave to Zero (M=00) Start the speedcook operation and carefully notice the cycling of the halogen lamps. At power levels of 10, both the upper halogen lamp pair and the lower halogen lamp should be on 100% of the time. However, remember that the upper rear halogen lamp always cycles at 85% of the upper halogen power level setting, so you will be able to see the upper rear halogen lamp cycle off briefly (see “UPPER HALOGEN LAMP BALANCE” for additional information). With approximately 1 minute remaining, the oven will stop and you will be instructed to turn over the food. Briefly open the door and close it, and then touch START to resume the remainder of the cooking time. At the end of the cooking cycle, repeat the steps above using the same hamburger selection (remember to once again set the microwave power level to zero (M=00)). Once again pay attention to the halogen lamp cycling. Since the oven is now hot, you should be able to visually see thermal compensation occurring. You will notice that both the upper and lower halogen lamp power levels have been decreased by some amount. What is important to note is that while the power levels have been reduced (thermal compensation), the power levels which will show in the display (if you touch the power level pad while speedcooking operation is occurring) will be the original power levels (U=10, L=10, and M=00). From a consumer’s point of view, if the consumer were to cook two hamburger patties, and then immediately cook two more patties, they could notice the halogen lamps cycling differently with the same selection used each time. This is perfectly normal when thermal compensation occurs. The consumer’s Owner’s Manual states the following: Page 21 - Lights “The halogen lights will dim and cycle on and off during a speedcook cycle, sometimes even at full power levels. This is normal. The oven senses the heat level and adjusts automatically.” Page 38 - Troubleshooting, Lights “Light during a speedcook cycle dims and cycles on and off, even at full power levels. This is normal. Power level has been automatically reduced because the oven is hot. The oven senses the heat level and adjusts automatically.” Thermal Protection If oven cavity temperatures reach somewhere in the range of 500°F to 600°F, or if a speedcooking selection is chosen which exceeds 12 minutes of cooking at halogen lamp power levels (upper and lower) greater than 7, all power levels (upper, lower, and microwave) will be reduced to 7 for the remainder of the speedcooking selection. This system allows for safe exterior operating temperatures. In the unlikely event that thermal protection is required, the consumer will not notice any change in the display readout (no power level change indication); however, they may notice that the halogen lamps are cycling differently than expected, due to the change in power levels. GEA00428

As was the case with thermal compensation, the control is provided by the thermistor and smart board, with the thermistor sensing the oven cavity temperature and the smart board providing the proper responses to lower all power levels to 7. GEA00429 SMART BOARD CN6 CN4 CN2 OVEN CAVITY THERMISTOR AND SMART BOARD Thermal Safety In the unlikely event that internal oven cavity temperatures exceed 600°F, speedcooking operation will be terminated. The oven cavity thermistor is constantly sensing oven cavity temperatures and providing input to the smart board. When the smart board determines that over 600°F has been reached, it will terminate speedcooking operation and return the oven display to its normal OFF position (with time-of-day clock showing in the display). When the unit cools, it will return to normal operation. Thermal safety provides an additional means of thermal protection, in addition to the thermal protection mode mentioned in the previous section. Damper Door Assembly The damper door assembly has a metal semi- round door, which rotates by control of a damper motor, to open and close off air from the damper chamber to the oven cavity. The thermal fuse and door sensing switch mount to the damper door assembly. GEA00430 THERMAL FUSE DOOR SENSING SWITCH DAMPER MOTOR During microwave oven cooking, the damper door is fully open, allowing air to travel through and around the magnetron tube into the oven cavity. GEA00431 DAMPER DOOR ASSY DAMPER DOOR SHOWN IN OPEN POSITION ALLOWING AIRFLOW INTO OVEN CAVITY During speedcooking operation (recipe or manual speedcook), the metal damper door rotates into the damper chamber, closing off air flow from the magnetron blower into the oven cavity. In doing so, heat from the oven interior is contained in the oven cavity. Damper Door Switch The damper door sensing switch is mounted to the damper duct. The switch monitors the metal door position and provides this information to the smart board (“Metal damper door open” or “Metal damper door closed”), which controls the direction and operation of the damper door motor. If the damper door sensing switch shorts (or opens), the damper motor will continually cycle the damper door open and closed until one complete switch cycle is detected.

Damper Door Open: The following illustration shows the position of the metal damper door in the open position. In this position, air blowing through and across the magnetron tube can enter the oven interior. With the damper door open, the damper door sensing switch is not depressed. GEA00440 Damper Door Open, Damper Door Open, Sensing Switch Not Depressed Damper Door Open, Sensing Switch Not Depressed Damper Door Closed: The following illustration shows the position of the metal damper door in the closed position. In this position, air from the magnetron blower will not enter the oven interior. With the damper door closed, the damper door sensing switch is depressed. GEA00441 Damper Door Closed, Damper Door Closed, Sensing Switch Depressed Damper Door Closed, Sensing Switch Depressed The following damper door positions will occur with various operations: • When the oven is not in use (power applied to the unit with time-of-day clock showing), the damper door will always be in the open position. • Speedcooking - At the start of speedcooking operation, the damper door will close, sealing off the damper duct from the oven cavity. The damper door will remain in the closed position during the entire speedcook operation, depressing the damper door sensing switch. • Microwave oven cooking - At the start of microwave cooking, the damper door will cycle one complete revolution (completely close and then reopen) and stop in the open position (damper door sensing switch not depressed). The oven cavity lamps will not illuminate during microwave operation. Oven Cavity Lamps The oven cavity lamps are located at the upper rear of the oven cavity and illuminate only when the oven door is opened. During microwave oven cooking, the oven interior can be illuminated by pressing the MICROWAVE OVEN LIGHT pad on the front panel. The lights will come ON and will remain ON until the end of the cooking cycle. In the event that it becomes necessary to change the lamps, it will be necessary to remove the oven from its installation. Thermal Fuse The thermal fuse is mounted to the top of the damper duct over a small rectangular hole in the duct. This hole allows the thermal fuse to sense temperatures inside the duct cavity. The fuse is secured to the damper duct with a small screw and retainer. In the event that it becomes necessary to change this fuse, it will be necessary to remove the oven from its installation (see page 32). Air Flow There are four fan motors in the Advantium design which provide airflow for proper cooling. During speedcooking (pre-selected recipe or manual speedcook), all four fan motors will run during the entire speedcook operation.

GEA00432 LOWER HALOGEN BLOWER UPPER HALOGEN BLOWER EXHAUST VENT MOTOR MAGNETRON BLOWER ASSEMBLY Exhaust Motor The exhaust motor helps remove heat from all components. The fan will be ON during cooking. At the end of speedcooking, the exhaust fan will continue to run for 1 minute (30 seconds on HIGH and 30 seconds on LOW), and the display will read “OVEN IS COOLING.” The fan will automatically shut off when the internal parts of the oven have cooled. GEA00433 HIGH LOW Upper and Lower Halogen Blowers The upper and lower halogen blowers only run during speedcook operations (speedcook recipe or manual speedcook selections). Both motors pull in fresh air from outside the unit and direct the air across the halogen lamps. Upper Halogen Blower As you will note from the illustration on the following page, the upper halogen blower pulls air in from the upper grille area. The air is then directed (blown) across the upper halogen lamp pair and exhausted back into the room through the lower grille area. The hot air directed across the upper halogen lamp pair is not controlled or directed by the exhaust motor. Lower Halogen Blower The lower halogen blower draws room air in through the upper grille area. The air is pulled down into the lower halogen blower and directed (blown) across the lower halogen lamp. The air is then exhausted through the lower grille area. Magnetron Blower Assembly During microwave operation, room air is drawn in through the upper grille area and into the magnetron blower area. The magnetron fan blows the cool air through and around the magnetron tube. The air then passes through the damper door assembly (damper door is open during microwave operation) into the oven cavity. As air enters the oven cavity, pressure builds up inside, forcing hot air out the top of the oven. The air passes across the humidity sensor and back into the room through the lower grille area.

Diagnosing Cooking Problems An important part of diagnosing any consumer cooking concern is listening carefully to the consumer describe the problem. Equally important is asking the consumer the right questions. The following diagnostic information is intended as a guide for you to follow when addressing cooking concerns. Food Items Appear to be Undercooked Foods which appear to be undercooked or partially cooked can be the result of any one of the following items. The possible causes listed below are sorted from most likely to least likely, with item #1 being the first item that you should check. 1. Is the consumer selecting the correct type of cooking (microwave vs. speedcook), and/or is the consumer using the correct time and power levels for the type, size, and quantity of food being cooked (see the Advantium cooking guide)? 2. Is the consumer using the correct cookware for the type of food being cooked (see pages 5 and 17 of the Owner’s Manual, and pages 5 and 6 of the Advantium cookbook)? 3. Is the consumer arranging the food properly on the metal cooking trays (see the Advantium cooking guide and page 7 of the cookbook)? 4. Is the turntable operating properly so that microwave energy and halogen heat are being evenly distributed to the food? 5. Inspect the upper and lower halogen lamp covers to ensure that they are free of grease and food spatterings. Build-ups of grease and food spatterings can cause a decrease in cooking performance. 6. Confirm proper line voltage to the unit (check voltage under full load). 7. Confirm that voltage compensation is operating properly (see page 18 of this service guide for details and diagnostic information). 8. Confirm that the upper and lower halogen lamps are operating (illuminating). 9. Check upper and lower halogen lamp operation at power level 10 and again at power level 5 to be sure that lamps are cycling properly. At this point, you must have a thorough understanding of power level operation, upper halogen lamp balance operation, and thermal compensation (see pages 17-21 of this service guide for detailed information). 10. Perform a microwave performance test (page 44) to confirm that microwave energy output (HV/magnetron circuit) is operating to specification. 11. Are all fan motors operating properly (page 23 of this service guide)? During speedcook operation, all fan motors must operate (exhaust fan, upper halogen lamp blower, lower halogen lamp blower, and magnetron blower). Improper airflow can cause the halogen lamps or magnetron tube to cycle on the thermal cut-outs (T.C.O.s). Food Items Appear to be Overcooked or Burned Foods which appear to be overcooked or burned can be the result of any one of the following items. The possible causes listed below are sorted from most likely to least likely, with item #1 being the first item that you should check. 1. Is the consumer selecting the correct type of cooking (microwave vs. speedcook), and/or is the consumer using the correct time and power levels for the type, size, and quantity of food being cooked (see the Advantium cooking guide)? 2. Is the consumer using the correct cookware for the type of food being cooked (see pages 5 and 17 of the Owner’s Manual, and pages 5 and 6 of the Advantium cookbook)? 3. Is the consumer arranging the food properly on the metal cooking trays (see the Advantium cooking guide and page 7 of the cookbook)? 4. Is the turntable operating properly so that microwave energy and halogen heat are being evenly distributed to the food? 5. Confirm proper line voltage to the unit (check voltage under full load). 6. Confirm that voltage compensation is operating properly (see page 18 of this service guide for details and diagnostic information).

7. Check upper and lower halogen lamp operation at power level 10 and again at power level 5 to be sure that lamps are cycling properly. At this point, you must have a thorough understanding of power level operation, upper halogen lamp balance operation, and thermal compensation (see pages 17-21 of this service guide for detailed information). 8. Confirm that thermal compensation is operating properly by following the thermal compensation test (see page 21 of this service guide). Diagnosing a “Dead” Unit A “dead” unit is better defined as a unit that appears to have no power to it (no clock display, oven cavity lamp, or key panel responses). The following components and associated wiring should be checked in the below order when diagnosing a “dead” unit. 1. At the power source, use your volt/ohmmeter and check the resistance from L1 to NEUTRAL. The resistance should be approximately 22.0 ohms. Note: The resistance reading that you just made is shown in the schematic diagram at the upper right corner of this page (low voltage transformer primary resistance). GEA00517 2. If you do not read continuity from L1 to NEUTRAL, suspect the following: • Open fuse • Open cavity T.C.O. • Low voltage transformer (open primary winding) • Open magnetron tube T.C.O. • Open thermal fuse • Defective smart board Also, check all associated wiring and wiring connections. 3. If you read approximately 22 ohms from L1 to NEUTRAL, suspect a defective smart board, loose wiring connection, or open secondary winding of the low voltage transformer.

Microwave Performance Test This test will verify that the microwave oven high voltage and magnetron circuits are operating to performance specifications. 1. Using only a WB64XO073 beaker, place a standard test load of 1 liter (1000 ml) of water in the beaker. Measure and record the water temperature prior to making the test. The water temperature should be between 59°F and 75°F. 2. Place the beaker in the center of the oven on the white ceramic microwave cooking tray. 3. Close the oven door. At the front control panel, select “Microwave, Time Cook, 2:03 Minutes, Power Level 10.” Press START to begin microwave cooking. GEA00437 OVEN LOCKED SELECT MUTE TIMER Select COOK TIME 2:03 M=10 4. At the end of the cooking cycle, remove the beaker of water, and measure and record the temperature. 5. The minimum difference between the initial and ending temperatures should be 32°F at 240 volts. If the water temperature rose but did not reach the 32°F minimum, suspect a problem with the line voltage (test under full load) or magnetron tube/ high voltage circuit. If the water temperature did not rise at all, suspect a problem in the high voltage circuit. Humidity Sensor Test Note: Oven should be plugged in at least 5 minutes before test. • Room temperature should not exceed 95°F. • Be sure the exterior of the cooking container and the interior of the oven are dry. • No sensor cooking is available during 5 minutes immediately after speedcook. The humidity sensor can be tested from the front control panel area using the following diagnostic procedure: 1. Disconnect the humidity sensor connector from the smart board (CN4, 3 pin - red connector plug located at the top of the smart board). 2. Using an ohmmeter, set the scale to Rx1000, and confirm the following approximate resistance readings: a. BLK - RED = 6.2K ohms b. RED - WHT = 3.1K ohms c. BLK - WHT = 3.1K ohms GEA00438 1 2 3 BLK RED WHT Microwave Leakage Test Caution: This test should not be performed during a speedcook operation. This test should only be performed during microwave-only operation. To perform a microwave leakage test: 1. Place 275 ml of water in a 600 ml beaker (WB64X5010). 2. Place the beaker in the center of the white ceramic tray. 3. Set the leakage meter to the 2450 MHz scale. 4. Program the microwave for 5 minutes (power level 10) and press START. 5. Hold the probe perpendicular to the surface being tested and scan surfaces at a rate of one inch/sec. Scan the following areas: • Entire perimeter of door and control panel • Viewing surface of door window • Exhaust vents

GEA00340 Note: Maximum allowable leakage should not exceed 4 MW/CM2, which is used to allow for measurement and meter accuracy. 6. Leakage should not exceed 4 MW/CM2. 7. Inform the manufacturer of any oven found to have emissions in excess of 5 MW/CM2. Try to determine the cause of excessive leakage and make repairs to bring the unit into compliance at no cost to owner. Instruct the owner not to use the oven until it has been brought into compliance. 8. Record the data on your service invoice and/ or microwave leakage report. Performance Test for Halogen Lamps Caution: When performing this test, use only a glass beaker. Plastic beakers will melt! Note: This test should be run when the oven is cool. 1. Place 1000 ml of water in a 1000 ml glass beaker. 2. Record the initial water temperature. 3. Place the beaker in the center of the black metal tray. 4. Program oven at U=10, L=10, and M=0 for 2.5 minutes and press START. 5. Record the ending water temperature. The minimum difference between the initial and ending temperature should be 15°F at 240 volts. Also, a continuity test can be taken on the upper halogen lamps by disconnecting the blue and white connectors located near the upper blower motor. Check the resistance with an ohmmeter. Key Panel Test If necessary, the key panel pads can be verified by a continuity test. For ease of handling, the key panel should be removed and placed on a flat protected surface. Check continuity between the connections at the end of the ribbon (use high ohm scale). GEA00346 To perform the test, press the appropriate pad on the front panel. While pressing the pad, check for continuity between the appropriate pins. For example, while pressing the SELECTOR DIAL, you should read continuity between pins 1 and 8. Fault Codes The smart board monitors various operations and can detect certain failure modes. In the event of specific failures, cooking will be terminated, a 4- beep signal will be heard, and a fault code will be displayed. Pressing the CLEAR pad will remove the fault code display unless the failure is a shorted key panel switch. Detection of a failed sensor will have no effect on features that do not use that sensor. F4 (open or shorted humidity sensor) and F6 (high cavity temperature during microwave cooking) codes apply only to microwave cooking.

The chart below indicates failure modes which can be detected and displayed: Y A L P S I D D E T C E T E D E R U L I A F 1 F r o tsi m r e h t ytiv a c n e v O n e p o 2 F r o tsi m r e h t ytiv a c n e v O d e tr o h s 3 F )s d n o c e s 0 6 > ( d e tr o h s le n a p y e K 4 F d e tr o h s r o n e p o r o s n e s ytidi m u H 6 F d e tc e te d e r u ta r e p m e t ytiv a c h gi H g n ik o o c n e v o e v a w o r c i m g n ir u d Sometimes fault codes will appear with no apparent cause. These codes and their symptoms include: • F1 - If the food is a large cold load that must cook over 5 minutes, the temperature of the cavity may not rise fast enough to change the thermistor resistance very much. The control believes that the thermistor is not responding because it is open, and thus displays the F1 code. This can be cleared at the end of the cycle and cooking will continue. • F4 - If there is an electrical surge or excessive line “noise” within the home, it could cause F4 to display on the control. The sensor will remain inoperable until the control is reset. This can be done by removing power (turning off the circuit) to the unit for 1 minute. NOTE: Replacing the humidity sensor will not cure this situation if it was due to electrical “noise.” • Interior oven lights stay on or off and do not respond to key commands - This is also caused by electrical surge or excessive line “noise.” Remove power (turn off the circuit) to the unit for 1 minute. Replacing parts will not solve the problem.
