GE Range Error Code F5

Control Sensor Circuit

GE codesGE range codes

Control Sensor Circuit — Supervisor Error. Redundant measurement circuits on main board do not match closely enough, or door latch motor is not disabled by temperature measurement circuits at the proper temperature.

First step from the service manual

Check sensor circuit for intermittent high resistance per F3 diagnosis. Press Clear/Off and reprogram control. If code reappears, replace control. DO NOT REPLACE LOCK MOTOR. Replace the main logic board.

What F5 means on a GE range

The F5 error code on a GE range indicates a loss of relay drive circuit. The control board has detected a failure in the circuit responsible for driving the relay that controls the door lock mechanism. This can involve the lock motor circuit, the sensor circuit monitoring lock position, or the control board's internal relay driver. A momentary power interruption can also trigger F5 without any underlying component failure, which makes accurate diagnosis critical before replacing parts.

For homeowners, F5 typically means the oven's electronic control has lost communication with or control of the door lock system. This is most commonly seen on self-cleaning ranges, where the door lock engages during the cleaning cycle. The oven may stop mid-cycle or refuse to start a self-clean cycle. Because a brief power fluctuation can cause this code, the first step is always to clear the code and try reprogramming the control before assuming a part has failed.

If F5 returns after clearing, the fault points to the lock circuit wiring, the door lock assembly itself, or in some cases the control board. Testing the lock circuit before replacing the control board is essential, since replacing the board will not fix a wiring or lock motor problem.

Common causes of F5

  1. 01

    Momentary power loss or voltage fluctuation

    Wiring / connection

    A brief interruption in power can cause the control board to lose the relay drive signal and trigger F5 without any physical component failure. Clearing the code and reprogramming the control resolves this in many cases.

  2. 02

    Faulty door lock assembly or lock motor

    Part replacement

    The door lock mechanism contains a motor and switch circuit that the relay driver must communicate with. If the lock motor has failed or its internal switches are open or shorted, the control detects a loss of drive circuit and sets F5.

  3. 03

    Damaged or loose wiring in the lock circuit

    Wiring / connection

    Wiring between the control board and the door lock assembly can develop open connections, pinched wires, or loose connectors, especially after repeated self-clean cycles expose the harness to high heat. This interrupts the relay drive signal and triggers F5.

  4. 04

    Failed control board relay driver

    Part replacement

    If the lock circuit and wiring test correctly but F5 persists after reprogramming, the internal relay driver on the control board itself may have failed. In this case the control board requires replacement.

Frequently asked questions about F5

What does F5 mean on a GE range?
F5 on a GE range means the control board has detected a loss of relay drive circuit. This circuit is responsible for controlling the door lock mechanism used during self-clean cycles. The code can result from a power fluctuation, a wiring fault in the lock circuit, a failed door lock assembly, or a failed control board.
How do I fix F5 on a GE range?
Start by pressing Clear/Off and reprogramming the control. A momentary power loss can trigger F5 without any actual part failure, and clearing the code may resolve it. If F5 returns, inspect the wiring harness connecting the control board to the door lock assembly for loose connectors or heat damage, then test the lock mechanism itself. Replace the door lock assembly if it fails testing, or the control board only after confirming the lock circuit is intact.
Can I still use my GE range if it shows F5?
Standard baking and cooktop functions may still operate depending on when and how F5 was triggered, but you should not attempt a self-clean cycle while the fault is active. The door lock circuit is directly involved in self-cleaning, and running that cycle with a compromised lock circuit is unsafe. Address the fault before using self-clean.
How much does it cost to fix the F5 error code on a GE range?
If the fix is simply clearing the code after a power fluctuation, there is no parts cost. A replacement door lock assembly typically runs between $40 and $100 for the part. A replacement control board is the more expensive repair, generally $150 to $350 or more depending on the model. Professional labor adds $100 to $200 in most markets. Because F5 does not always require a new control board, testing the lock circuit before ordering parts can save significant money.
Will replacing the control board fix F5 on a GE range?
Not necessarily. GE specifically cautions against replacing the control board and lock assembly without first checking the lock circuit, because F5 can be caused by a wiring fault or a failed lock motor rather than the board itself. If the lock circuit wiring and lock assembly test good and the fault persists after reprogramming, then the control board is the likely cause and replacement is appropriate.
