• Check door alignment: Ensure the doors close fully and are level. Adjust hinges if necessary so the gasket contacts the cabinet evenly.
• Inspect gasket: Look for twisted or damaged door seals that prevent full closure.
• Test door switch: Manually operate the switch and observe if the interior light turns on/off (when briefly powered). Replace if faulty.
• Magnet check: For magnetic reed systems, ensure the magnet in the door is present and correctly positioned.
• PCB input: If hardware is fine, the PCB input circuit may be defective and require board replacement.
