Check door closure:

• Inspect for food packages or shelves preventing the door from closing fully.
• Ensure the unit is level so the door can swing closed properly.

Inspect gasket:

Door switch:

• Locate the door switch and press it manually; if the alarm does not stop or the light does not change, the switch may be faulty and should be replaced.
