GE Oven/Range F3 Error Code
Oven temperature sensor circuit is open (broken connection), preventing accurate temperature reading.
Common causes
- Faulty oven temperature sensor
- Loose or damaged wiring
- Faulty control board
How to fix it
- Disconnect power.
- Check sensor connector at back of oven for secure fit.
- Measure sensor resistance; infinite reading indicates open sensor, so replace sensor.
⚠ When to call a pro: If sensor and wiring check out, control board is likely faulty.
