Possible Causes
Unplugged or broken temperature sensor, Sensor reading outside valid range, Faulty control board input
How to Fix / Troubleshooting
Safety: Disconnect power before accessing sensors or the control board.
Steps:
- Inspect temperature sensors: Access the cabinet and evaporator thermistors by removing interior panels. Ensure each sensor is connected and not physically damaged.
- Check connectors: At the main control board, verify that all thermistor connectors are fully seated.
- Test sensors: Use a multimeter to measure resistance. Replace any sensor that reads open (OL) or short (0 Ω).
- Control board: If all sensors test good and are connected, the control board may not be interpreting the signals correctly and may need replacement.
After repair: Restore power and confirm that the numeric temperature display returns and updates as the unit cools.
