GE Appliances Oven Error Code F4
Oven temperature sensor short circuit
The most common cause of the F4 error on a GE Appliances oven is sensor shorted internally (~65% of cases); start with: power cycle the oven.
What Does Error Code F4 Mean on a GE Appliances Oven?
Oven temperature sensor short circuit.
The Electronic Range Control reads near-zero resistance from the oven temperature sensor (RTD), interpreting it as a short circuit. With no trustworthy temperature, the oven won't heat. A shorted sensor or a pinched harness grounding the circuit is the usual cause.
What Causes Error Code F4?
Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Sensor shorted internally 65% of cases
- 2 Wiring pinched causing short 25% of cases
- 3 ERC board sensor input shorted 10% of cases
How to Fix GE Appliances Oven Error Code F4
- 1
Power cycle the oven
Turn off the circuit breaker for 5 minutes, then restore power to see if the short was a transient fault.
- 2
Test the sensor
With power off, measure the RTD — about 1,080 ohms at room temperature; a near-zero reading confirms a shorted sensor.
🔩 Multimeter⚠️ Disconnect power before testing. - 3
Inspect the sensor wiring
Look for the sensor lead pinched or chafed against the cavity or rear panel, shorting it to ground.
- 4
Replace the sensor
Shorted sensors can't be repaired; fit a matching GE oven temperature sensor and verify resistance.

How to Reset Error Code F4
After replacing the sensor, restore power at the breaker and run a short bake cycle to confirm F4 has cleared. If it returns immediately, the short is in the harness, not the sensor.
Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional
If a new sensor reads correctly and the harness is sound but F4 persists, the ERC board's sensor input circuit is shorted and the board needs professional replacement.
