Wine cooler has power (lights on) but compressor and fans do not run; interior warms up.

Safety first: Unplug the unit before accessing the control board or sensors.

• Step 1 – Verify temperature setting: Ensure the setpoint is below room temperature and that the unit is not in a demo or showroom mode (if applicable).
• Step 2 – Check for error codes: Look for any codes on the display and address them first.
• Step 3 – Test temperature sensor: If the sensor reads falsely cold, the board will not energize the compressor. Test the cabinet thermistor and replace if out of spec.
• Step 4 – Inspect main control board: Remove the rear panel and examine the board for burnt relay contacts or damaged traces. Lightly tap the relay area (with power disconnected) to check for loose components.
• Step 5 – Replace main control board: If the sensor is good and the board still does not send power to the compressor or fans, replace the Café-compatible main control board.

After replacement, set the desired temperature and monitor for proper cycling.
