Wine cooler does not power on at all; display is blank and no lights or fans run.

Safety: Before opening the unit, unplug it. Do not work on live circuits.

Troubleshooting steps:

• Verify outlet: Plug a lamp or other appliance into the same outlet to confirm it has power. Reset any tripped breakers or GFCI outlets.
• Inspect power cord: Check the Arctic King power cord for cuts, burns, or kinks. If damaged, replace the power cord assembly rather than attempting a repair.
• Check power switch: Some models have a rocker or touch power switch. Ensure it is in the ON position and not stuck.
• Access main control board: Remove the rear lower panel to access the control board. With the unit unplugged, inspect for burnt components or loose connectors.
• Test incoming voltage (advanced): If you are qualified and have a multimeter, carefully test for line voltage at the board input with the unit plugged in. If voltage is present but the board is dead, the board's power supply is likely failed.
• Replace main control board: If the board shows visible damage or no low-voltage outputs, replace it with the correct Arctic King main control board for your model.

Warning: If you are not comfortable working with mains voltage, contact a professional technician.
