Whirlpool Whirlpool WMH53521HZ 2.1 cu. ft. Over-the-Range Microwave MECH-DOOR Error Fix: Door Not Latching Properly

The microwave door does not close, latch, or seal properly. The door hooks (plastic latches that engage the interlock switches) may be worn, cracked, or broken. Inspect the hooks — they should snap firmly into the switch slots. Replace broken door hooks. The door hinge springs may be worn, not pulling the door tight. On over-the-range models, the door can sag if a hinge breaks. Check both hinges for damage. A door that does not seal can also cause microwave energy leakage — do not use the microwave if the door does not close firmly.
