GE Range Error Code F2

Oven exceeded 590°F with door in unlocked position or exceeded 990°F with door locked

GE codesGE range codes

Oven exceeded 590°F with door in unlocked position or exceeded 990°F with door locked. Can also be caused by high resistance connection within sensor circuit, sensor exposed to temperature of 40°F or lower, interference from cordless telephone/ham radios, moisture, or improper ground.

First step from the service manual

Test operation of door lock switch on self clean models. Test relay contact operation. Check appliance ground. Verify oven and cordless phone are not on same circuit.

What F2 means on a GE range

The F2 error code on a GE range indicates the control board has detected an over-temperature condition in the oven cavity. Specifically, it triggers when the oven temperature exceeds 630°F with the door unlocked, or exceeds 930°F when the door is locked during a cooking or self-clean cycle. The most common hardware culprits are welded relay contacts on the control board (which allow heating elements to stay energized even when the board commands them off), high resistance in the oven temperature sensor circuit caused by poor terminal crimps, deformed terminals, loose connections, or intermittent solder joints, and electrical noise interference corrupting the sensor signal.

For homeowners, this code means the oven's brain detected that the inside of the oven got hotter than it should have. This can happen because a component on the control board got stuck and kept the heating element on when it should have turned off, or because the temperature sensor is sending a false reading due to a bad connection somewhere in its wiring. Either way, the oven shuts down as a safety measure to prevent damage or fire. The root cause is not always a failed sensor itself, but rather the wiring and relay hardware that surround it.

Common causes of F2

  1. 01

    Welded relay contacts on control board

    Part replacement

    Relay contacts on the control board can fuse together, causing the bake or broil element to remain energized even when the board sends an off command. This allows the oven temperature to climb unchecked until the F2 threshold is reached.

  2. 02

    High resistance in temperature sensor circuit

    Wiring / connection

    Corroded, crimped, or deformed terminals and loose connections in the sensor wiring harness add resistance to the circuit, causing the control board to receive an artificially elevated temperature reading and trigger F2 even when the oven is within normal range.

  3. 03

    Intermittent solder joint in sensor circuit

    Part replacement

    A cold or cracked solder joint on the sensor circuit board connector can cause erratic resistance readings that spike high enough to register as an over-temperature condition, typically appearing and disappearing as the range heats and cools.

  4. 04

    Electrical noise interference in sensor circuit

    Wiring / connection

    External electromagnetic interference or a failing component elsewhere in the range can inject noise into the temperature sensor signal line, producing false high-temperature readings that the control board interprets as an F2 condition.

Frequently asked questions about F2

What does F2 mean on a GE range?
F2 means the control board detected an oven over-temperature condition. The oven exceeded 630°F with the door unlocked, or exceeded 930°F with the door locked during a cooking or self-clean cycle. The oven shuts down automatically as a safety response. The cause can be welded relay contacts keeping the heating element on, or a faulty sensor circuit sending a false high reading.
Is it safe to use my GE range when it shows the F2 error code?
No, you should not continue using the oven while F2 is active. The code indicates either the oven is genuinely overheating due to a stuck relay, or the control system has lost reliable temperature data. Both conditions present a fire risk or risk of damage to the oven interior and components. Disconnect power to the range until the cause is diagnosed and resolved.
How do I fix F2 on a GE range?
Start by disconnecting power and inspecting the oven temperature sensor wiring harness for loose connections, corroded or deformed terminals, and poor crimps at the connector ends. Reseat all connections and check for visible damage. If connections look good, test the sensor resistance at room temperature (most GE sensors read around 1080 ohms at 75°F). If the sensor checks out, inspect the control board for signs of welded or burned relay contacts, which require replacing the control board.
How much does it cost to fix the F2 error code on a GE range?
If the fix is a loose or corroded sensor connection, the repair costs nothing beyond your time. A replacement oven temperature sensor typically runs $20 to $60 for the part. A replacement control board is the most expensive path, ranging from $150 to $350 for the part depending on the model, plus labor if you hire a technician. Total professional repair cost including labor usually falls between $200 and $450 for a board replacement.
Can resetting my GE range clear the F2 error code?
Disconnecting power for 30 seconds may clear the F2 code temporarily, but if the underlying cause is welded relay contacts or a degraded sensor connection, the code will return. A reset is useful as a first step to confirm whether the fault is intermittent or persistent, but it does not fix any failed hardware. If F2 returns after a reset, inspect the relay contacts and sensor wiring before using the oven again.
