Possible Causes
Faulty fresh food thermistor, Stuck air damper open, Main control board temperature logic failure, User settings too cold
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing sensors or dampers.
- Verify settings: Set fresh food to 37°F (3°C) and freezer to 0°F (-18°C). Avoid max cold settings unless needed.
- Check damper: Inspect the air damper for a door stuck open, allowing too much cold air into the fresh food section. Replace if broken.
- Test thermistor: Measure the fresh food thermistor resistance and compare to spec. Replace if out of range.
- Control board: If damper and thermistor are good but unit still overcools, the main control board may be misreading temperatures and require replacement.
