GE Range Error Code FA

The FA code on a GE range indicates a LIN communication error between the main control board and the RPSM AUX auxiliary board. The two boards are unable to exchange data signals properly. This code only appears on ranges that are equipped with the AUX board. The fault is most commonly traced to the AUX board itself or the wiring connecting the two boards.

The FA code is a communication fault between internal control boards, and its effect on range operation can vary. Some functions may work normally while others may not respond correctly, since the AUX board supports supplementary functions. It is best to avoid relying on the range until the fault is diagnosed and resolved, as unpredictable control behavior can pose a safety concern.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the FA code, but if the underlying cause is a failed AUX board or a damaged wiring harness, the error will return. A reset is a reasonable first step to determine whether the fault is intermittent, but a persistent FA code requires physical diagnosis and repair of the affected components.

A knowledgeable DIYer can check the wiring harness and connectors between the main board and AUX board for visible damage or loose connections, which requires no parts. However, if the AUX board itself has failed, replacing it requires identifying the correct part for your specific model and safely accessing the internal electronics of the range. If you are not comfortable working with appliance control boards, a qualified technician is recommended.

If the repair requires replacing the RPSM AUX board, parts alone can range from roughly $50 to $200 or more depending on the specific model. Adding professional labor, the total repair cost typically falls in the range of $150 to $400. If the fault is caused by a loose or damaged wiring harness connection, the repair cost may be significantly lower.
