Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Microwave does not start even though the controls appear functional.
• Microwave displays a door or open/close-door message after the door is closed.
• Microwave stops unexpectedly when the door or latch position changes.
• Microwave may show inconsistent door-status detection.

Check Before Replacing

• Verify that the door closes fully and that no dishware, packing material, debris, or misaligned door hardware obstructs the latch area.
• With the microwave unplugged, visually inspect the switch actuator, latch interface, wiring connectors, and terminals for looseness, damage, or corrosion.
• If the appliance-specific service documentation permits it, check switch continuity with a meter only after disconnecting power and isolating the switch wiring; use the specified terminals and door-open/door-closed states for that model.
• Do not bypass the door-interlock switch or operate the microwave with its cabinet removed; door-switch symptoms can also be caused by latch alignment, wiring, control, or other interlock components.
