Safety first: Unplug the unit before moving sensors or accessing the control board.

- 2. Inspect sensor placement: Confirm the cabinet sensor is in its original position and not directly in the cold air stream.
- 3. Reset control: Disconnect power for 5 minutes to reset the control logic.
- 4. Replace sensor: If short cycling persists, replace the cabinet NTC sensor.
- 5. Professional diagnosis: If unresolved, the main control board may require replacement.
