Microwave door will not stay closed or pops open during cooking.

Safety first: Unplug the microwave.

• Check for obstructions: Ensure no food or debris is stuck around the door seal or latch area.
• Inspect latch hooks and catch: Look for broken plastic or missing springs in the latch mechanism. Replace the latch assembly if damaged.
• Check door seal: A deformed seal can push the door open. Inspect the gasket and replace if badly distorted.
• Test after repair: Close the door firmly and start a short cycle with a cup of water. Observe whether the door remains securely closed.
