LG Microwave DOOR Code — Door Not Closed or Latch Not Engaged
What this means
The DOOR message on an LG microwave means the door is not being detected as fully closed and latched. Microwaves have multiple safety interlocks that prevent operation unless the door is securely closed. This can be caused by food debris in the door seal area, a misaligned door, or a worn latch mechanism.
Step-by-step fix
3 stepsClose the door firmly
Open and close the microwave door with a firm push. Listen for the click of the latch engaging.
Check for obstructions
Inspect the door seal area for food debris or objects that prevent full closure. Clean the seal area with a damp cloth.
Check turntable and rack
Ensure the turntable and any rack inside the microwave are properly seated and not preventing the door from closing.
When to call a professional
If the door latch is worn or broken, a technician should replace it. Door interlock switches are safety-critical components.
