Frigidaire FEFB89ECG Service Data Sheet

having electrical and mechanical training and a level of knowledge of these subjects generally considered acceptable in the appliance repair trade. The manufacturer cannot be responsible, nor assume any liability for injury or damage of any kind arising from the use of this data sheet. SAFE SERVICING PRACTICES To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be observed. The following are examples, but without limitation, of such practices. 1. Before servicing or moving an appliance remove power cord from electrical outlet, trip circuit breaker to OFF, or remove fuse. 2. Never interfere with the proper installation of any safety device. 3. GROUNDING: The standard color coding for safety ground wires is GREEN or GREEN WITH YELLOW STRIPES. Ground leads are not to be used as current carrying conductors. It is extremely important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a potential safety hazard. p/n 316441476 (0608) SERVICE DATA SHEET Electric Ranges with ES 330/335/345 Electronic Oven Controls RTD SCALE Temperature (°F) Resistance (ohms) 32 ± 1.9 1000 ± 4.0 75 ± 2.5 1091 ± 5.3 250 ± 4.4 1453 ± 8.9 350 ± 5.4 1654 ± 10.8 450 ± 6.9 1852 ± 13.5 550 ± 8.2 2047 ± 15.8 650 ± 9.6 2237 ± 18.5 900 ± 13.6 2697 ± 24.4 ELECTRONIC OVEN CONTROL FAULT CODE DESCRIPTIONS Runaway Temperature. Shorted Keypad. Bad Micro Identification. Bad EEPROM Identification/Checksum error. Open probe connection. Shorted Probe connection. Cooktop Lockout error (some models). Maximum oven door unlock time exceeded. Maximum oven door unlock attempts exceeded. Maximum oven door open time exceeded. Maximum oven door lock time exceeded. Maximum oven door lock attempts exceeded. Likely Failure Condition/Cause Suggested Corrective Action Fault Code 1. (F10 only) Check RTD Sensor Probe & replace if necessary. If oven is overheating, disconn power. If oven continues to overheat when the power is reapplied, replace EOC. Sev overheating may require the entire oven to be replaced should damage be extensive. 2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power. 3. (F11, 12 & 13) If fault returns upon power-up, replace EOC. 1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance ch If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wi harness between EOC & Sensor Probe connector. 2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD Sen Probe. Check for shorted Sensor Probe harness between EOC & Probe connector. 1. (F40) Check the wiring. 2. (F40) Replace the Cooktop Lockout Control Board. 3. (F40) Replace EOC. 1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch. 2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary. 3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor C 4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock M Assembly. 5. (F90, 91, 92, 93 & 94) Lock Motor continuosly runs - if Micro Switch is open, replace Lock M Assembly. 6. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch. 7. If all situations above do not solve problem, replace EOC. ELECTRONIC OVEN CONTROL (REAR VIEW) IMPORTANT DO NOT REMOVE THIS BAG OR DESTROY THE CONTENTS WIRING DIAGRAMS AND SERVICE INFORMATION ENCLOSED REPLACE CONTENTS IN BAG 4. Prior to returning the product to service, ensure that: • All electric connections are correct and secure. • All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts. • All uninsulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels. • All safety grounds (both internal and external) are correctly and securely reassembled. OVEN CALIBRATION Set the electronic oven control for normal baking at 350°F. Obtain an average oven temperature after a minimum of 5 cycles. Press STOP/CLEAR to end bake mode. TEMPERATURE ADJUSTMENT 1. Set EOC to bake at 550°F. 2. Within 5 seconds of setting 550°F, press and hold the bake pad for approximately 15 seconds until a single beep is heard (longer may cause F11 shorted keypad alarm). 3. Calibration offset should appear in the display. 4. Use the slew keys to adjust the oven temperature up or down 35°F in 5°F increments. 5. Once the desired (-35° to 35°) offset has been applied, press STOP/CLEAR. Note: Changing calibration affects normal Bake mode. The adjustments made will not change the Self-Cleaning cycle temperature.
