Interior light stays on even when the door is closed, causing the cabinet to warm up.

Safety: Unplug the unit before adjusting switches or wiring.

Steps:

• Check door closure: Ensure the door closes fully and is not obstructed by shelves or bottles.
• Inspect door switch: Locate the door switch (magnetic or mechanical). Press it manually to see if the light turns off. If not, the switch or control is faulty.
• Adjust magnet: If using a magnetic reed switch, ensure the magnet in the door aligns with the switch location. Reposition or replace the magnet if loose.
• Replace switch: Install a new door switch assembly if the existing one does not change state when actuated.
• Control board check: If the switch tests good but the light remains on, the main PCB’s light driver may be stuck and the board may need replacement.
