Whirlpool Microwave Door Error: Open/Close Door Message Fix

Quick Answer

Whirlpool microwaves have 3 door interlock switches that must all confirm the door is closed before the microwave will operate. The 'Open/Close Door' or 'Door' error means at least one switch is not engaging. The most common cause on Whirlpool over-the-range models is a worn door latch hook - the small plastic hook on the door that presses the interlock switches.

Whirlpool microwaves have 3 door interlock switches that must all confirm the door is closed before the microwave will operate. The 'Open/Close Door' or 'Door' error means at least one switch is not engaging. The most common cause on Whirlpool over-the-range models is a worn door latch hook - the small plastic hook on the door that presses the interlock switches. After thousands of open/close cycles, the hook wears down and no longer fully depresses the switch. The second cause is a failed interlock switch itself - the switch contacts corrode from steam exposure. On Whirlpool countertop models, the door may be slightly warped from being slammed, preventing the hooks from aligning with the switches. Before any internal repair, try cleaning the door latch area and closing the door firmly with extra pressure.

Frequently Asked Questions

Can I bypass the door switch to use my microwave?
NEVER bypass a microwave door interlock switch. These switches prevent the magnetron from operating with the door open. Microwave radiation exposure at close range causes burns and tissue damage. The switches also prevent a fire hazard. If a switch has failed, replace it - they cost $10-20.
My microwave door error comes and goes. Is it dangerous?
An intermittent door error means a switch is making inconsistent contact. This is not immediately dangerous (the microwave will not run when the switch is open), but it indicates a wearing component that will fail completely. Fix it now while it is intermittent rather than waiting for total failure.
KitchenAid microwave shows the same door error. Same fix?
Yes. KitchenAid over-the-range microwaves are manufactured by Whirlpool and share the same door interlock system, latch hooks, and switches. The diagnosis and repair procedure is identical.
