GE oven F3 code: oven temperature sensor fault

The control is getting a bad reading from the oven temperature sensor, so it will not heat. GE says the oven sensor usually needs to be replaced.

Likely causes

Listed from most to least common.

1. Failed oven temperature sensor
2. Sensor plug loose behind the oven back wall
3. Sensor wire damaged by heat or a self-clean cycle
4. Faulty electronic oven control

How to fix the F3 code

Unplug the oven or switch it off at the breaker before removing any panel or filter.

1. 1

   Step 1: Reset power at the breaker

   Turn off the circuit breaker for the oven for one to two minutes, then turn it back on. Watch the display to see if F3 returns.

2. 2

   Step 2: Test the oven

   Start a bake at 350°F. If it heats normally and the code stays away, it was a one-off glitch.

3. 3

   Step 3: Look at the sensor

   With the breaker off and the oven cold, find the thin probe at the top rear of the oven. A bent, loose or scorched sensor points to the fault.

4. 4

   Step 4: Replace the sensor

   The sensor is held by two screws inside the oven and plugs in just behind the back wall. Fit a new one only with the breaker off and the oven fully cool.

You'll need: Nut driver set, flashlight, multimeter.

Parts that may need replacing
