GE Range Error Code F800

F800 indicates a memory error on the main logic board of your GE range. The board's internal memory has failed to function correctly during operation or a self-diagnostic check. This is a hardware-level fault within the control board itself. Replacement of the main logic board is the standard repair for this code.

A memory error on the main logic board can cause unpredictable behavior in the range's operation, including loss of temperature control or unresponsive controls. Continuing to use the range in this state is not recommended. It is best to stop using the appliance until the logic board has been replaced.

The cost depends on whether you hire a technician or replace the part yourself. A replacement main logic board for a GE range typically costs somewhere in the range of $150 to $350 for the part alone, depending on the model. If you use a professional repair service, labor charges will add to that cost, bringing the total repair estimate to roughly $250 to $550 or more. Getting a firm quote from a local technician before proceeding is advisable.

The repair requires replacing the main logic board, which is a job many experienced DIYers can handle if they are comfortable working with appliance electronics. You will need to disconnect power to the range before beginning any work. Sourcing the correct replacement board for your specific model is essential, as boards are model-specific. If you are not comfortable working with electrical components, a qualified technician should perform the replacement.

Cutting power to the range at the circuit breaker for several minutes may temporarily clear the F800 code. However, if the main logic board's memory hardware is genuinely faulty, the error will return after the range is powered back on and goes through its self-diagnostics. A reset is a useful first step to confirm the fault, but it is not a fix.
