Wine cooler interior light stays on even when the door is closed, causing excess heat inside.

Safety: Unplug the unit before adjusting or replacing the door switch.

Steps:

• Check door alignment: Ensure the door closes squarely and is not sagging. Adjust hinges if necessary so the switch or magnet aligns correctly.
• Inspect door switch: Locate the door switch and press it manually. If the light does not go off, the switch may be faulty.
• Replace switch or magnet: Replace the door switch or door magnet if they are damaged or misaligned.
• Control board check: If a new switch does not resolve the issue, the main control board may be misinterpreting the door signal and may need replacement.
