To enter Service Mode, disconnect main power to the oven for at least 15 seconds. Reconnect power and enter ‘0803’ on the keypanel within 5 minutes after the control initializes. Select SERVICE from the SPECIAL MODES menu. *SERVICE MODE* menu appears. Navigate through SERVICE MODE menu by pressing the pads next to the NEXT and BACK keys. Available troubleshooting modes are: • COOKING LOADS (Verify proper operation of cooking elements, microwave and convection fan. See troubleshooting section below.) • DOOR LATCH (Verify proper operation of door lock motor and switches) • DOOR POSITION (Verify proper operation of door sense switch) • RTD (Displays oven sensor temperature in red on right display) • VENT FAN (Verify proper operation of ventilation fan) • R COOLING FAN (Verify proper operation of cooling fan) • L COOLING FANS (Verify proper operation of mag cooling fan, HVT fan and mag stirrer fan) • OVEN LIGHT (Verify proper operation of oven lights) • OFFSET (Oven calibration offset in non-microwave modes) • DISPLAY (Verify operation of display segments by allowing all of them to be turned on and off. Press CLEAR/OFF key to return display to normal) • KEYS (Verify proper operation of keypanel) • LINE VOLT(AGE) (Displays line voltage L1-L2 in the upper temperature display) • F CODES (Displays up to last 7 ERC Failure Codes) NOTE: Always check failure codes and then clear them. • COSENSOR (KENMORE ONLY) Press EXIT to return to normal cooking mode. ACRONYM TABLE CAP = capacitor COM = common CO Sensor (on some models) = carbon monoxide sensors for Sens-a-Clean (on some models) ERC = engineering range control F codes = ERC failure codes HVT = high voltage transformer J = jumper/connector on a PCB K = relay on a PCB MAG = magnetron MLB = main logic board MPB = main power board MW = microwave NC = normally closed NO = normally opened PCB = printed circuit board such as MLB or MPB RTD = resistive thermal device (oven temperature sensor) TCO = thermal cutout TROUBLESHOOTING COOKING LOADS IN SERVICE MODE CAUTION: TO PREVENT ELECTRICAL SHOCK, USE EXTREME CAUTION WHEN DIAGNOSING OVEN WITH OUTER COVERS REMOVED AND POWER “ON”. THE HIGH VOLTAGE CIRCUIT OF THE MAGNETRON POWER SECTION (HVT, CAPACITOR, DIODE, MAGNETRON) IS 4400 VOLTS POTENTIAL WITH RESPECT TO GROUND. WAIT AT LEAST 5 MINUTES AFTER POWERING DOWN BEFORE SERVICING THE MAGNETRON POWER SECTION. CAUTION: HEATSINKS ON MAIN POWER BOARD ARE ELECTRICALLY LIVE. TAKE SPECIAL PRECAUTIONS WHEN TROUBLESHOOTING THE MAIN POWER BOARD WITH POWER “ON”. WAIT AT LEAST 5 MINUTES AFTER POWERING DOWN BEFORE SERVICING THE MAIN POWER BOARD. Cooking loads (bake, broil, convection elements and convection fan) can be energized individually through SERVICE MODE (Press key next to COOKING LOADS, then appropriate load.) When the appropriate load is turned on in SERVICE MODE, first verify that the element is heating or the fan is turning. If load is not energized, check AC relay voltages according to the second column in the following table: SERVICE MODE (CONT.) RELAY CONTROL TABLE Note: To turn off all loads that are energized in COOKING LOADS, press the CLEAR/OFF key or exit the COOKING LOADS menu. If load is not turned off, additional loads can be turned on at the same time. If AC voltage measures OK, then check the load (element, fan, lock motor, HVT, etc.) and/or wiring to the load and repair/replace as required. If there is no AC voltage supplied to the load through the power relays per the wiring schematic, then check the DC power supply voltages from the Main Power Board (MPB-J3 connector) to the Main Logic Board (MLB-J5 connector) according to the following table: If voltages do not measure according to the table above, replace Main Power Board. If voltages measure OK, then measure DC voltages according to the previous relay control table (relay control signals columns 3, 4 and 5). If the MLB- J3 pins do not provide the correct DC voltages, then replace the Main Logic Board. SERVICE MODE (CONT.) If display is blank, oven light does not operate when the oven door is opened and keypanel does not respond, first check DC power supply voltages. Next, check DC voltages at MLB J2: J2-2, J2-4, J2-6, J2-8 should be +12VDC. If not, replace Text Display and/or Time/Temp Display. If DC power supply voltages are OK: If display is blank and keyboard is not responding, replace MLB. If just the display is blank, replace the display. If just the keyboard is not responding, check glass touch display. If OK, replace MLB. If oven light does not turn on when door is opened, check oven light relay per relay troubleshooting table. If relay voltages are OK, check door sense switch per DOOR SWITCH section. MICROWAVE a. Microwave Leakage Test Place 275mL of water in a 600mL beaker. Place beaker in center of oven shelf. Set meter to 2450Hz scale. Enter SERVICE MODE, press COOKINGLOADS, then MW. Time for 5 minute test. Hold probe perpendicular to surface being tested and scan surface at rate of one inch/sec. Test following areas: Entire perimeter of door and control panel. Viewing surface of door window. Exhaust vents. Maximum leakage not to exceed 4 mW/cm2. Record Data on service invoice and microwave leakage report. NOTE: Maximum allowable leakage is 5 mW/cm2. 4 mW/cm2 is used to allow for measurement and meter accuracy. Inform manufacturer of any oven found to have emissions in excess of 5 mW/cm2. Make repairs to bring the unit into compliance at no cost to the owner and try to determine cause. Instruct owner not to use oven until it has been brought into compliance. b. Performance Testing Standard test load will be 1 liter (1000mL) of water with an initial temperature 59° ~ 75°F in a 1000mL beaker (PN WB64X73). Record initial water temperature. Place beaker in center of middle oven shelf. Enter SERVICE MODE, press COOKINGLOADS, then MW. Time for 2 minutes, then open door. Record end water temperature. The difference between the initial and ending temperature should be 12°F minimum at 240VAC. NOTE: Standard sparkle blocks are not applicable for testing of the microwave assist mode in this oven. c. High-Voltage Capacitor WARNING: The capacitor holds its 4400V charge for at least 2 minutes after power is removed. Always be certain that the capacitor is discharged before servicing. Mechanically discharge by placing an insulated handle screwdriver between the diode connection of the capacitor and oven chassis ground. d. Magnetron The magnetron cannot be serviced from the component compartment; the unit must be removed from the wall. Be sure to replace the ground wire under the screw head when installing. Make sure that the magnetron is seated flat against the mounting surface. e. Special assembly note Elements, convection fan and oven light contain special radiation screens and chokes. Be sure to replace these in the oven cavity. Take special care not to strip any screws when replacing these components. 229C4059P444-1 The branch circuit load for one wall-mounted oven or one counter-mounted cooktop is the rating on the nameplate of the appliance. The branch circuit load for a counter-mounted cooktop and not more than two wall-mounted ovens – all supplied from a single branch circuit and located in the same room – shall be computed by adding the nameplate ratings of the individual appliances and treating this total as equivalent to one range.
