GE Range Error Code F5x

The F5x code on a GE range indicates that the temperature measurement circuit redundancy check within the Main Logic Board has failed. This is an internal self-diagnostic fault, meaning the board detected a problem within its own temperature monitoring circuitry. It is not caused by the oven temperature sensor itself. The repair path leads directly to replacing the Main Logic Board.

The F5x code indicates a failure in the board's internal safety redundancy check for temperature measurement. Because this check exists to confirm reliable temperature control, continued use of the oven with this fault present is not advisable. The range may not accurately regulate or report oven temperature, which poses a potential safety and cooking reliability concern.

Repair costs for an F5x fault depend primarily on the cost of the replacement Main Logic Board, which can vary by model, plus any applicable labor charges. Parts alone typically range from around $100 to $300 or more depending on the specific GE model, with professional labor adding additional cost. Getting a repair estimate before proceeding is a good idea, as total costs may approach the value of older units.

The F5x fault requires replacement of the Main Logic Board, which is a more involved repair than swapping a sensor or fuse. A technician comfortable with appliance disassembly and component replacement can perform this repair, but it does require working near line-voltage connections. If you are not experienced with appliance electrical work, professional service is recommended.

A power reset, such as unplugging the range or tripping the circuit breaker for a few minutes, may temporarily clear the F5x code. However, because the fault originates from a hardware failure within the Main Logic Board, the code will return once the board performs its redundancy check again during operation. A reset does not repair the underlying board failure.
