Possible Causes
Misreading temperature sensor, Sensor not properly clipped to evaporator or wall, Control board calibration error, Wiring harness resistance causing offset
How to Fix / Troubleshooting
Safety first: Disconnect power before handling sensors or control boards.
- Verify actual temperature: Place an accurate thermometer in the freezer for at least 30 minutes. Compare reading to the display.
- Inspect sensor placement: Ensure the thermistor is properly clipped to the evaporator or wall as designed. A sensor hanging loose in air can misread temperature.
- Check sensor resistance: Unplug the unit, disconnect the sensor, and measure resistance. Compare to the tech sheet chart. Replace if out of spec.
- Inspect harness: Look for splices or damage that could add resistance. Repair with proper connectors.
- Control board replacement: If sensor and wiring are correct but alarm persists with accurate temperature, replace the main control board.
