Wine cooler is completely warm; compressor does not run at all, but interior lights and display work.

Safety: Disconnect power before accessing the compressor compartment. Capacitors and terminals can be hazardous.

Steps:

• 1. Listen for compressor: With the unit powered (briefly), check if you hear a humming or clicking from the compressor. Then disconnect power before touching anything.
• 2. Access rear compartment: Remove the lower rear panel to expose the compressor and start device.
• 3. Inspect start relay/PTC: Remove the start device from the compressor. Look for burn marks or melted plastic. Replace if damaged.
• 4. Check wiring: Ensure all wires to the compressor and start device are secure and not corroded.
• 5. Test compressor windings: With the start device removed and power off, measure resistance between compressor terminals. If readings are open or shorted, the compressor is likely failed and requires professional replacement.
• 6. Evaluate control board: If the compressor and start device are good, the main control board may not be sending power to the compressor. Replace the board if confirmed.

Warning: Compressor replacement and refrigerant handling must be done by a licensed technician.
