Possible Causes
Open oven temperature sensor (RTD), Broken sensor wiring harness, Loose sensor connector at control board, Damaged sensor plug
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool.
- Access sensor:
- Locate the oven temperature sensor probe on the rear wall of the oven cavity.
- Remove the two screws and gently pull the sensor forward.
- Disconnect the sensor connector.
- Test sensor:
- Measure resistance across the sensor terminals at room temperature.
- Expected reading is ~1050–1100 Ω at 70°F (21°C).
- If the circuit is open (infinite resistance) or far out of range, replace the oven temperature sensor.
- Check harness:
- If the sensor tests good, inspect the harness from the sensor to the EOC for breaks or loose connections.
- Reseat the connector at the control board.
- Control board:
- If wiring and sensor are good but F30 persists, the sensor input circuit on the EOC may be faulty; replace the electronic oven control board.
