Roper ERC Fault Codes

Many failure codes are caused by a faulty timer (also known as the Electronic Range Control). Sometimes, even when the failure code implies that another component has failed this can actually be a timer problem (whereby the timer is not displaying the correct fault code). If you are not sure whether the code you are seeing is due to a problem with the timer please call us, or send us an email, since we can help you determine whether the failure code is likely a timer problem or a problem with some other component. We can repair most timers so if you are sure your problem pertains to the timer (or ERC) please fill out a repair service request and send us your timer to be repaired.

2-Digit Failure Code

Fault CodeCondition/DescriptionResolution
F0 or F1 or F5Failed Electronic Range Control (ERC)Rebuild Electronic Range Control/Clock (ERC)
F2 - E0Oven temp too high
  1. Test operation of door lock on self-clean models
  2. Test relay contact operation
  3. High resistance in oven temperature sensor
F3Open oven temperature sensor or thermal fuse, bad oven temperature sensor harness, or oven temperature sensor resistance too highReplace oven temperature sensor or thermal fuse
F4Shorted oven temperature sensorReplace oven temperature sensor
F6Problem in time keeping circuit
  1. Reset time and/or cooking operation
  2. Check for proper ground
F7Stuck function switch or button on Electronic Range Control (ERC)Rebuild Electronic Range Control/Clock (ERC)
F8Failure of Electronic Range Control (ERC)Rebuild Electronic Range Control/Clock (ERC)
F9Door lock circuitCheck wiring and test operation of door lock switch
DOORBake or BroilReplace latch switch if defective.Replace wire from 10-pin connector if defective
  • Defective latch switch
  • Shorted wire from ERC 10-pin connector, pin 10 to ground
  • Door latched
DOORSelf-CleanReplace latch switch if defective.Replace wire from 10-pin connector if defective
  • Defective latch switch
  • Open wire from ERC 10-pin connector, pin 10 to ground
  • Door not latched
LOCKIf not in Self-Clean, the oven temperature sensor resistance too high.Check oven temperature sensor resistance, wire harness and connections, replace defective component
