Wine cooler shows E5 and compressor may not start or may short-cycle.

Safety: Unplug the wine cooler before accessing the compressor compartment. Capacitors and compressor terminals can present shock hazards.

Troubleshooting steps:

• 1. Verify power supply: Ensure the outlet provides stable voltage (typically 120V in North America). Avoid extension cords and power strips.
• 2. Access compressor area: Remove the rear lower access panel to expose the compressor, start device, and overload protector.
• 3. Inspect start device: Check the Electrolux compressor start relay/PTC for burn marks, cracking, or a burnt smell. Gently shake it; if it rattles excessively, it may be failed.
• 4. Check connections: Ensure all spade connectors on the compressor terminals and overload are tight and not discolored from heat.
• 5. Replace start device/overload: If visibly damaged or suspected faulty, replace the start relay and overload protector as a set, using the correct Electrolux-specified parts for your model.

Important: If the compressor hums loudly and clicks off even with a new start device, the compressor itself may be seized or internally damaged. Compressor replacement requires specialized tools and refrigerant handling certification; contact a professional.
