Wine Enthusiast wine cooler displays E5 and may shut down or fail to cool.

Safety: Unplug the cooler before working near the compressor or electrical components. Allow hot components to cool.

• Check ventilation: Ensure there is adequate clearance around the sides, back, and top of the wine cooler as specified in the Wine Enthusiast manual. Remove any items blocking the rear grille.
• Clean condenser coils: Pull the unit away from the wall and remove the lower rear access panel. Use a soft brush and vacuum to clean dust from the condenser coils and fan area.
• Inspect condenser fan: Verify that the condenser fan (near the compressor) spins freely by hand. If it is seized or noisy, it may need replacement.
• Check start relay and overload: With power disconnected, remove the plastic cover on the side of the compressor. Inspect the start relay and overload protector for signs of burning or cracking. A rattling relay when shaken is often failed.
• Replace faulty components: Install a compatible Wine Enthusiast compressor start relay/overload kit if damaged. Ensure all connections are tight.
• Restart and monitor: Reassemble the rear panel, plug in the unit, and monitor for normal compressor start-up. The E5 code should clear once the compressor runs without overheating.

If the compressor hums and clicks off or E5 persists despite a good relay and fan, the compressor or control board may be failing. This requires a sealed-system technician.
