How to Fix / Troubleshooting
Safety first: Disconnect power before servicing.
- Identify cavity: Consult the tech sheet (usually behind the control panel or in the lower drawer) to determine whether F3E1 refers to the upper or lower oven sensor.
- Access sensor: Remove the appropriate oven racks and locate the sensor on the rear wall of that cavity. Remove screws and pull sensor forward.
- Measure resistance: Test the sensor at room temperature (~1080–1100 Ω). Replace if out of range.
- Check harness and connectors: Inspect and reseat connectors at both the sensor and control board. Repair any damaged wiring.
- Replace control if needed: If the sensor and wiring are good, replace the electronic oven control board.
