Possible Causes

How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before accessing the oven sensor or control board.
- Test sensor: Remove the oven temperature sensor and measure resistance at room temperature (~1080–1100 Ω). Replace if open or out of range.
- Check harness and connectors: Inspect the wiring from the sensor to the control board for breaks or loose connections. Reseat connectors at both ends.
- Control board check: If sensor and wiring are good, the control board sensor circuit may be defective and require replacement.
Warning: Do not operate the oven with a known sensor fault; temperature control will be inaccurate.
