Display shows E5 and the wine cooler may shut down or fail to cool after running briefly.

Safety warning: Unplug the unit before touching the compressor, fan, or wiring. Components may be hot.

Steps to address E5:

• Check ventilation: Ensure the wine cooler has adequate clearance around the sides, back, and top as specified in the Haier manual. Move it away from walls or heat sources if necessary.
• Clean condenser coils: Remove the rear lower panel to access the condenser. Use a soft brush and vacuum to remove dust and lint from the condenser fins.
• Verify condenser fan operation: With the rear panel off, briefly plug in the unit and observe whether the condenser fan starts when the compressor runs. Unplug again before touching anything.
• Inspect fan motor: If the fan does not run, check for obstructions and spin the blade by hand (with power off). If stiff or seized, the fan motor is likely bad.
• Check compressor start device: With power disconnected, remove the plastic cover on the side of the compressor. Inspect the PTC start relay and overload protector for burn marks or rattling pieces.
• Replace faulty components: Install a Haier-compatible condenser fan motor and/or compressor start relay/overload as needed. Ensure all connections are tight and correctly oriented.
• Reassemble and test: Refit the rear panel, restore power, and monitor operation. The E5 code should clear once the compressor runs without overheating.

Important: If the compressor is extremely hot to the touch and fails to start even with a new start device, the compressor itself may be failing and will require professional sealed-system service.
