Likely causes
Listed from most to least common.
- Failed oven temperature sensor
- Sensor wires pinched or shorted to the oven frame
- Sensor lead damaged by a self-clean cycle
- Faulty electronic oven control
How to fix the F4 code
Unplug the oven or switch it off at the breaker before removing any panel or filter.
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 F4 returns.
Step 2: Run a short bake
Set the oven to 350°F and stay nearby. If F4 returns or the oven seems too hot, turn the breaker off.
Step 3: Check the sensor
With the breaker off and the oven cool, look at the sensor probe at the top rear of the oven. Make sure it is not bent or touching the oven wall.
Step 4: Replace the sensor
If F4 keeps returning, fit a new sensor. It is held by two screws and plugs in behind the back wall.
You'll need: Nut driver set, flashlight, multimeter.
Parts that may need replacing
Check your model number on the label inside the door or on the back before ordering.

When to call a technician
Call a technician if F4 returns after a new sensor is fitted. A shorted harness or a failed control board needs electrical testing.
A typical repair for this code costs $120–$300 in the US, including parts and labor. Prices vary by area and model.
Models this applies to
- GE electric and gas ranges (JB, JGB, JS and JGS series)

Common questions
›Did self-cleaning cause my F4 code?
It can. The very high heat of self-clean can damage the sensor or its wires. A power reset sometimes clears it, but a damaged sensor must be replaced.
›How much is a GE oven sensor?
The sensor itself usually costs $20 to $50. A technician visit to fit it typically runs $120 to $300 in total.
