Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing sensors or control boards.
Steps:
- Locate the fresh food temperature sensor (often behind a small cover on the rear wall of the fridge section).
- Inspect for physical damage or moisture.
- Disconnect and test resistance; compare to spec at known temperature.
- Check continuity of the harness from sensor to main board.
Corrective action: Replace the fresh food sensor if readings are incorrect or wiring is damaged. If F1 persists with a new sensor, suspect the main control board.
