GE Oven F3 — Open Oven Temperature Sensor
The oven control reads the temperature sensor (RTD probe) as open. The oven will not heat to protect itself.
Common causes
- Failed temperature sensor (most common)
- Damaged sensor wiring or connector
- Failed electronic oven control (ERC)
Fix it step by step
- Turn off the circuit breaker
- Pull the oven out and unplug the sensor at the rear
- Test sensor resistance — should be ~1080Ω at room temperature
- Replace the sensor if out of spec; if good, replace the ERC
Typical cost: $30 DIY part · $200–$450 pro
