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.
|F0||Function key stuck||Replace touch pad or if touch pad is part of the clock, repair the clock (ERC).|
|F1||System Watchdog Circuit||Press "Cancel", if beeping continues after 30 seconds, repair the main control board (also called clock or ERC).|
|F2||Heating mode high temperature||This alarm is activated when the ERC senses a runaway heat condition or when the temperature exceeds "runaway limits". The ERC will beep until the cancel or another function is selected. If the alarm repeats the F2 code check the oven sensor and wiring after first checking for a stuck relay. If alarm goes away verify the oven will complete a clean cycle without any type of failure.|
|F3||Shorted oven temperature sensor (RTD)||Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.|
|F4||Open oven temperature sensor (RTD)||Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.|
|F6||EEPROM checksum error||Repair main control board (also called clock or ERC).|
The main control operates a series of software commands, which control the various features and functions of the oven. Each function or operation has a numerical value assigned to it. The numerical values can be added up - this is called the check sum operation. Every time the system is powered up and after each clean cycle the system performs a check sum and compares the value to the value programmed into the software (stored in memory).
An EEPROM check sum error or F6 code occurs when the values differ. If this happens, repair the main control board (also called clock or ERC).
|F7||Door lock enabled above temperature||Check the door lock switches and wiring.|
|F8||Door locking switch||Check the door lock switches and wiring.|
