LG Microwave DOOR error code

Difficulty: Easy · Cost: $0–$80 · Duration: 2–5m

The DOOR error means your LG microwave detected that the door is not fully closed or the latch is not engaging correctly. Microwaves will not operate unless the door is completely shut as a safety requirement — microwave energy cannot be contained in an open or partially open cavity. This is commonly caused by an obstruction preventing the door from latching or a cooking rack sitting out of position. Closing the door firmly usually clears it. If the error persists the door latch may need professional inspection.

Common causes

  • Door was not closed firmly enough before starting
  • Packing material or a foreign object is preventing the door from latching
  • Cooking rack is out of position and blocking the door from closing fully
  • Door latch is worn, bent, or damaged

How to fix it

  1. 1

    Check around the door opening for any packing material, food debris, or foreign objects preventing the door from closing

  2. 2

    If a cooking rack is installed make sure it is correctly seated and not sticking out

  3. 3

    Close the door firmly until it clicks shut

  4. 4

    If the DOOR error persists after closing firmly contact a qualified technician to inspect the door latch assembly
