Wine cooler not cooling at all; interior at room temperature, display powered.

Safety: Unplug the cooler before accessing the compressor compartment. Components may be hot.

Steps:

• Confirm power: Ensure the outlet has power and the unit is switched on. Check the circuit breaker.
• Listen for operation: When plugged in, listen for a click or hum from the compressor. Repeated clicking without running suggests start component issues.
• Access compressor components: Remove the rear lower panel to expose the compressor, start relay/PTC, and overload protector.
• Inspect and test start relay and overload: Remove the relay and overload from the compressor. Check for burn marks or melted plastic. Test for continuity with a multimeter; replace any open or obviously damaged parts.
• Check compressor windings: With components removed, measure resistance between the compressor terminals. Infinite resistance or a direct short to ground indicates a failed compressor.
• Replace faulty parts: Install an EdgeStar-compatible start relay/PTC and overload protector if they test bad. If the compressor itself is defective, the entire sealed system repair must be done by a professional.

Note: If the compressor never receives power (no voltage at its terminals when it should be running), the main control board or wiring is likely at fault and may need replacement.
