Possible Causes
Shorted oven temperature sensor, Sensor wires shorted to chassis, Moisture in sensor connector
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the sensor or wiring.
- Inspect sensor wiring: Remove the oven's rear panel or pull the wall oven to access the sensor harness. Look for insulation damage where wires may touch metal.
- Test sensor: Disconnect the sensor and measure resistance at room temperature. A reading significantly lower than ~1080 Ω or near 0 Ω indicates a shorted sensor; replace it.
- Check connectors: Inspect the sensor plug and EOC connector for moisture, corrosion, or carbon tracking. Clean and dry as needed; replace damaged connectors.
- Replace sensor: If the sensor is shorted or suspect, install a new GE Profile sensor and secure wiring away from sharp edges.
Note: Continued use with a shorted sensor can cause inaccurate temperatures and potential overheating.
