GE Oven Error Code F8

The F8 code on a GE oven signals an EEPROM data shift failure. The EEPROM is a memory chip on the electronic control board that stores calibration and operational data. When the control board detects that this data has shifted or become corrupted, it triggers the F8 fault. A one-time occurrence may be caused by a power fluctuation, but a code that keeps coming back points to a failing control board.

Using the oven with an active F8 code is not advisable. Because the EEPROM stores temperature calibration data, a data shift failure means the control board may not be operating with accurate parameters, which could lead to incorrect temperatures or unpredictable behavior. Stop using the oven until the fault is resolved or cleared and confirmed non-recurring.

A power reset by turning off the breaker for 30 seconds may clear the F8 code if the EEPROM corruption was caused by a temporary power event. However, if the code reappears after reset, the EEPROM or control board has a hardware failure that a reset cannot resolve. Repeated F8 codes require control board replacement.

Start by cutting power to the oven at the breaker for 30 seconds, then restore power to see if the F8 code clears. If it returns repeatedly, GE's diagnostic guidance calls for replacing the electronic control board, as the EEPROM is integrated into that assembly. Control board replacement on a GE oven is a moderately difficult repair requiring you to disconnect wiring harnesses and secure the new board in the same position as the original.

The electronic control board for a GE oven typically costs between $150 and $350 for the part, depending on the model. If you hire a technician, expect an additional $100 to $200 in labor, bringing total repair costs to roughly $250 to $550. If you are comfortable working with appliance electronics and can confirm the correct part number for your model, this is a DIY-capable repair that would bring costs down to just the part.
