What Does Error F3 Mean?
The GE Oven F3 error code indicates a malfunction in the oven temperature sensor, which can lead to incorrect temperature readings or the oven failing to heat properly. This may be caused by a defective sensor, faulty wiring, or issues with the control board misreading the sensor signal. Symptoms include the F3 error display and potential intermittent errors with other codes like F2 or F5.
Common Symptoms:
- F3 displayed and oven will not heat
- Error appears when setting temperature or mid-cycle
- Possible sporadic errors with other codes (F2,F5)
Possible Causes
- Defective temperature sensor (high)
- Faulty or damaged wiring / poor connection in sensor circuit (medium)
- Control board misreading sensor due to board fault (medium)
How to Fix Error F3
DIY Fix Basic Reset and Visual Check
- Turn off power at circuit breaker or unplug oven
- Wait ~5 minutes, restore power and check if F3 returns
- Visually inspect sensor inside oven for obvious damage or loose mount
Technician Only Diagnose and Repair Sensor Circuit
- Disconnect power and remove sensor (probe inside oven)
- Use multimeter to measure sensor resistance at room temp
- Inspect and test wiring continuity from sensor to control board
- Replace temperature sensor if out-of-range
- Repair or replace damaged wiring/connectors
- If F3 persists, test and potentially replace control board
Parts needed: Oven temperature sensor (RTD), Wiring harness/connectors, Electronic control board (if needed)
- If you’re not comfortable with multimeter testing or internal component access
- If error persists after replacing sensor and repairing wiring
- If visible electrical damage (burnt wiring/control board) is found
