Safety: Unplug the wine cooler and allow components to cool before touching. High voltages are present on inverter circuits.

Steps:

Basic checks: Verify that the outlet has power and that the power cord is intact. Confirm that the condenser fan runs briefly when the unit is powered on.
Access compressor compartment: Remove the rear lower panel to expose the compressor and any attached inverter or start module.
Inspect wiring: Look for loose or burned connectors at the compressor and inverter module. Reseat connectors if they appear loose.
Listen for compressor: When powered, the compressor should hum or vibrate slightly. If completely silent and EC appears, the inverter or compressor may be faulty.
Do not bypass safety devices: Do not attempt to hard‑wire the compressor or bypass the inverter. This can be dangerous and damage the unit.
Professional service: EC faults typically require diagnosis with proper tools. Contact a qualified technician to test compressor windings and inverter outputs and replace the inverter module or compressor as needed.
