Freezer beeping intermittently with door-ajar alarm even when door is closed

Safety: Basic checks can be done with power on; unplug before electrical testing.

Steps:

• 1. Check alignment: Ensure the door is level and not sagging. Adjust hinges if the door rubs or does not close squarely.
• 2. Inspect gasket: Look for gaps, tears, or hardened sections of the gasket. Close the door on a strip of paper at several points; if it pulls out easily, the seal is weak.
• 3. Clean gasket: Wipe the gasket and mating surface with warm soapy water to remove grease and debris.
• 4. Test door switch: For mechanical switches, press and release to see if the interior light responds. For magnetic reed switches, use a magnet to test operation. Replace if faulty.
• 5. Check magnet: Ensure the door magnet (if used) is present and firmly seated in the door frame.
