GE Oven Error Code F5

F5 on a GE oven means the electronic control board has detected a sensor circuit supervisor failure. The control board monitors the temperature sensor circuit continuously, and F5 is triggered when that supervisory function identifies a problem it cannot resolve. The fault most often points to the control board itself, though the oven temperature sensor and its wiring should also be checked.

No, the oven will not operate normally with an active F5 code. The control board disables the oven when it detects a sensor circuit supervisor failure as a safety precaution. Attempting to bypass or ignore this fault is not advisable since the board cannot reliably control oven temperature without a functioning sensor supervisory circuit.

Cutting power to the oven at the breaker for 30 seconds and restoring it may temporarily clear the F5 code. However, if the control board or temperature sensor has genuinely failed, the code will return once the oven attempts to operate again. A reset is a useful diagnostic step to confirm whether the fault is persistent, but it is not a fix.

GE's recommended first step for F5 is replacing the electronic control board. Before doing that, check the oven temperature sensor resistance with a multimeter, which should read around 1080 ohms at room temperature for most GE models. Also inspect the wiring harness and connector between the sensor and the board for damage or corrosion. If the sensor checks out, replacing the control board is the correct repair.

The electronic control board for a GE oven typically costs between $150 and $350 for the part, depending on the specific model. A service call and labor to replace it will add $100 to $200 in most markets. If the oven temperature sensor is the cause instead, the sensor itself usually costs $20 to $50, making it worth testing the sensor before purchasing a control board. DIY replacement of either part is feasible for someone comfortable with appliance repair.
