How to repair a sub-zero wine cooler that is not turning on?

To repair a Sub-Zero wine cooler that is not turning on, follow these steps:
1. Check the power supply: Ensure the wine cooler is properly plugged into a working power outlet and the power cord is intact.
2. Test the circuit breaker: Check the circuit breaker or fuse box to make sure the circuit hasn't tripped.
3. Inspect the control panel: Look for any error codes or issues on the control panel that may indicate a problem.
4. Clean the condenser coils: Dust and debris on the coils can cause cooling problems. Clean them using a coil brush or vacuum cleaner.
5. Verify the door switch: Ensure the door switch is engaging properly when the door is closed.
6. Call a professional: If the wine cooler still doesn't turn on, contact a certified Sub-Zero technician to diagnose and repair any internal electrical or component issues safely.
