How to Fix / Troubleshooting

Basic checks:

Confirm that the appliance is not in demo/showroom mode (refer to user manual for exit procedure).
Verify that temperature settings are not set to OFF or holiday mode.

Control system:

If the display responds but cooling never starts, the main control board or thermostat circuit may be faulty.

Check wiring from the board to the compressor and fans for loose or disconnected plugs.
