Wine cooler not cooling at all; interior stays at room temperature and compressor is silent.

Safety: Unplug the cooler before accessing electrical components. Use caution around line-voltage wiring.

Steps:

• 1. Confirm power: Check that the outlet has power by plugging in another device. Inspect the power cord for damage.
• 2. Check control settings: Ensure the unit is switched on and not in standby mode. Verify that the set temperature is below room temperature.
• 3. Listen for any sounds: If fans run but the compressor is silent, suspect the compressor start components or control board.
• 4. Inspect compressor start relay and overload: Remove the rear panel, locate the compressor, and remove the start device. Look for burn marks or rattling parts. Replace with a compatible Kalamera start relay/overload if damaged.
• 5. Check wiring and fuses: Some models include inline thermal fuses or cutoffs. Inspect wiring harnesses for breaks or loose connectors between the control board and compressor.
• 6. Evaluate control board: If the compressor never receives power even when cooling is demanded, the main control board may be faulty and require replacement.
• 7. Professional help: If replacing the start components and control board does not restore compressor operation, the compressor itself may be failed and will need a licensed technician to replace.
