GE Range Error Code F025

F025 indicates that the oven user interface board and the oven relay board cannot establish communication with each other. These two boards must exchange data continuously for the range to operate correctly. The error can result from a loose harness connection, damaged wiring, or a failure in one of the boards. It does not necessarily mean a board has failed, as a simple connection issue can trigger the same code.

It is generally not recommended to continue using the range while F025 is active. Because the relay board controls the heating circuits, a breakdown in communication between the boards means the oven may not respond to commands correctly or at all. Operating the appliance in this condition could lead to unpredictable behavior, so it is best to leave the range unpowered until the fault is diagnosed and resolved.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose harness connector, there may be no parts cost at all, though a service call typically runs between $75 and $150. A replacement wiring harness generally costs between $20 and $60 in parts. If a control board replacement is required, parts alone can range from $100 to $300 or more per board, with labor adding to the total.

A power reset is the recommended first step and will clear the error if it was caused by a temporary communication glitch. Disconnect power to the range for at least 30 seconds, then restore power. If F025 returns immediately or shortly after, the underlying cause is a physical issue such as a loose connector or damaged harness that will need to be inspected and corrected.

Start by disconnecting power for 30 seconds and restoring it to see if the error clears on its own. If it returns, inspect the wiring harness that runs between the user interface board and the relay board, checking both connector ends for secure seating, bent pins, or visible damage. Clean any corroded contacts if present. If the wiring checks out and the error persists, one or both control boards may need to be replaced.
