• Unplug the wine cooler from the wall outlet for 60 seconds, then plug it back in to reset the system
• Check that the power cord is fully inserted into the wall outlet and not loose
• Verify the wall outlet is working by plugging in another appliance (like a lamp)
• Inspect the power cord for any visible damage, fraying, or bent prongs
• Check your home's circuit breaker panel to ensure the breaker serving the outlet is in the ON position
• Move the wine cooler away from other high-power appliances that may cause electrical interference
• Allow 5-10 minutes after power restoration before expecting normal cooling operation
• Verify temperature settings are correct after the error clears
• Ensure the cooler has adequate ventilation clearance on all sides (at least 2-3 inches)
