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

Safety first: Unplug the wine cooler before accessing the rear compartment or electrical components.

• 1. Confirm power: Verify the outlet has power and the unit is switched on. Check the household breaker and ensure the power cord is fully inserted.
• 2. Listen for activity: With the unit plugged in, listen for any fan or compressor noise. If completely silent, suspect a control or power issue.
• 3. Inspect control settings: Make sure the unit is not in standby or demo mode and that a reasonable temperature is selected.
• 4. Access rear compartment: Remove the rear lower cover and inspect the compressor, start relay, and overload protector for burn marks or loose connections.
• 5. Test start components: With power disconnected, remove and test the start relay and overload for continuity. Replace if open or visibly damaged.
• 6. Check main PCB: Inspect for burnt components or a blown fuse. If the board is damaged or not sending power to the compressor or fans, replace it.
• 7. Professional help: If the compressor windings test bad or the sealed system is suspected, contact a certified technician.

Warning: Do not bypass safety devices such as overload protectors.
