How to Fix / Troubleshooting

Safety first: Unplug the microwave before adjusting hinges or latches.

Steps:

Inspect door hooks: Open the door and examine the plastic latch hooks. If they are cracked, bent, or worn, the door may not stay closed. Replace the door latch assembly if damaged.
Check hinges: Gently lift the door up and down. Excessive play indicates loose hinges. Tighten hinge screws carefully.
Check cabinet alignment: Ensure the microwave is not twisted by uneven countertop surfaces. Level the unit using shims if necessary.
Test closure: Close the door firmly and check that it clicks and stays closed during a test run.

Warning: Do not operate the microwave with a door that does not close securely; this is a radiation safety risk.

Microwave door will not latch properly or pops open during cooking.
