Frigidaire FFCM0724LW 0.7 cu ft Countertop Microwave MECH-DOOR Error Fix: Door Latch or Switch Failure

The microwave will not start because the door latch does not engage the door switches properly. Microwaves have 2-3 interlock switches that must all close when the door is shut — this is a safety system to prevent radiation leakage. Check the door hooks for cracks or wear. Test each door switch for continuity. Replace damaged door hooks or failed switches. WARNING: Never bypass a door interlock switch.
