Step-by-Step Repair

  1. 1

    Try to release the door gently

    Press the door release button firmly several times while gently pulling the door. If the button feels mushy or doesn't click, the button spring or latch may be broken inside. Try pressing from slightly different angles. Do not yank the door.

  2. 2

    Use a thin tool to release the latch

    If the button doesn't work, slide a thin flathead screwdriver or putty knife into the gap between the door and the frame, near the latch. Gently push the latch mechanism to release it. Work slowly to avoid scratching the finish.

  3. 3

    Inspect the door button and spring

    Once the door is open, unplug the microwave. Examine the door button. On most LG models, you can pry off the inner door panel to access the latch mechanism. Check if the button spring is broken or if the plastic latch hook has snapped.

  4. 4

    Replace the door latch assembly

    Order a replacement latch assembly for your exact LG model number (on the sticker inside the door). Remove the inner door panel screws, swap out the old latch for the new one, and reassemble. Test the door open/close action multiple times before using the microwave.

If That Didn't Work

  • Warped door from heat damage
  • Misaligned door hinges
  • Child lock feature accidentally enabled — check the control panel

When to Call a Professional

If the door hinges are bent or the door frame is warped, a replacement door assembly may be needed. A pro can source and install this.
