How to Fix / Troubleshooting

Safety Warning: Do not force the door open with tools, as this can damage the interlock system.

Steps:

  • 1. Allow cooling: Let the microwave sit for a few minutes; slight vacuum or thermal expansion can temporarily make the door tight.
  • 2. Inspect latch area: Check around the door edges and latch openings for food debris or sticky residue. Clean thoroughly.
  • 3. Test release button: Press the door release button repeatedly to feel for sticking or grinding. If it feels loose or jammed, the internal lever may be broken.

Persistent door opening issues usually require replacement of the door latch assembly or release lever, which involves removing the outer cover and is best done by a technician.
