Possible Causes
Shorted freezer thermistor, Thermistor harness short to ground, Moisture in sensor connector, Failed control board input
How to Fix / Troubleshooting
Safety first: Disconnect power before testing or replacing sensors.
- Locate the freezer thermistor: Refer to your model's tech sheet (often behind the kick plate or rear panel) for exact location.
- Inspect for moisture: Look for condensation or ice around the sensor and connector. Dry thoroughly and correct any air leaks that cause condensation.
- Measure resistance: At room temperature, check thermistor resistance. A reading near 0 Ω indicates a short. Replace the thermistor if shorted.
- Check harness routing: Ensure the harness is not pinched by panels or screws, which can cause shorts.
