Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before accessing the rear of the range.
- Inspect sensor inside oven: Confirm the probe is securely mounted and not loose or hanging.
- Check rear connections:
- Pull the range out carefully.
- Remove the rear panel and locate the sensor wires leading to the control board.
- Ensure the connector is fully seated and wires are intact.
If wiring is intact, the sensor should be tested with an ohmmeter and replaced if open. If a new sensor does not resolve F3, the control board may have a defective sensor input circuit.
