Wine cooler interior light stays on even when the door is closed, causing warming and condensation.

Safety: Disconnect power before working on the door switch or control board.

• Check door alignment: Ensure the door closes fully and is not sagging. Adjust hinges if necessary.
• Test door switch: Manually press the switch (if visible) and see if the light goes off. If not, the switch or control circuit is faulty.
• Inspect magnet and reed switch: For magnetic systems, confirm the magnet in the door is present and aligned with the frame sensor. Replace missing magnets or sensors.
• Temporary mitigation: Remove the light bulb or disconnect the LED module to prevent heating until the switch or PCB can be replaced.
