Wine cooler not cooling at all; interior at room temperature and compressor is not running.

Safety: Unplug the cooler before any work. Mains voltage is present at the compressor circuit.

• Check power and outlet: Verify the outlet has power by plugging in another device. Confirm the unit's power cord is intact.
• Control settings: Ensure the unit is switched on and not in demo or standby mode.
• Listen for sounds: When plugged in, listen for a click or hum from the compressor. No sound may indicate a control or relay issue.
• Inspect compressor components: Remove rear panel and check the compressor start relay and overload protector for burns or damage. Replace if suspect.
• Check wiring: Look for loose or disconnected wires at the control board and compressor.
• Control board: If the compressor never receives power and relays do not click, replace the main control board.
• Compressor failure: If proper voltage reaches the compressor but it does not start, the compressor may be failed and requires sealed‑system service or replacement of the unit.
