1. Kitchenaid Microwave Door Sensor (Or Switch) is Faulty
A KitchenAid microwave door sensor, also referred to as the door switch, is a simple function that prevents the microwave from operating immediately you open the door.
Microwave sensors are about 2CM long and black in color with protruding metal prong terminals.
A KitchenAid microwave can have 3 or 4 door sensors, depending on the model. Once the sensors prevent the microwave from operating, the magnetron antennas don’t energize and therefore don’t burn out.
With the door in closed state, the sensor and the door latch (sometimes referred to as the hook) come into contact thereby activating the door sensors.
Unfortunately, functionality fails if the door sensor or switch is faulty. In such a case, the best thing to do would be to replace the door sensor.
Kitchenaid Door Switch Replacement
You will need to replace the Kitchenaid microwave door switch if it fails the continuity test. Follow these steps to replace the faulty door switch:
- Turn the microwave off and unplug it from the power outlet.
- Unthread the screws that hold the microwave on the kitchen cabinet, pull the unit from the cabinet, and place it on a sturdy surface.
- With a screwdriver, unthread the screws securing the grill, slide the grill to release and remove, and remove the screws securing the control panel and pull the panel forward to detach.
- Unthread the screws securing the switch assembly, press the release tab, and actuator to release the defective door switch.
- Disconnect the wire connector to release the switch, install the new door switch by first installing the new wire connector, position the new door switch in the assembly, and snap it into place.
- Realign the switch assembly to the frame, thread the screws to secure, reposition the control panel, and tighten its screws to hold.
- Fix the grill back and re-thread the screws to secure.

With the repair complete, plug the unit is back to power, and the microwave oven should be ready for use.
2. Problem with the Door Latch
If your KitchenAid microwave door isn’t working as it should, there’s a high chance the door latch is faulty.
The common problems with the door latch are that:
- The door latch stuck.
- The door latch button is faulty.
- The door latch lever is faulty.
Here’s how to fix each issue:
The Door Latch Stuck
The first thing to do if your microwave’s door latch fails to work is to check whether the latch is stuck. Also, check the latch to ensure it can properly connect and disconnect from the microwave door.
To test whether the door latch is stuck:
Press the door button to open the door. If the door does not open, open it manually by pulling. If the door opens by means of manual pulling, it means it’s stuck.
The door latch is stuck because there is dirt and debris stuck within. Clean the door latch to fix this problem.
The Door Latch Button is Faulty
If your Kitchenaid microwave has a door button, it could be that a problem with the button is causing the door latch to fail.
Press the button to feel the resistance.
If the button presses with no resistance, it’s faulty. If the button presses with resistance but you hear a clicking sound, it indicates that the button is not making contact with the door release mechanism.
The only best fix in this case is to replace the door button by getting a new touchpad compatible with your model. To do this:
- Turn the microwave off and unplug it from power.
- Open the door, and remove the rack, turntable, and turntable support.
- Remove the unit from the cabinet and disassemble it to get to the faulty touchpad.
- Disconnect the touchpad.
- Install the new touchpad/control panels and assemble the unit.
- Put the microwave back into the cabinet and secure it.
- Restore power to the unit and test the new door button.
The Door Latch Lever is Faulty
Check the door latch lever to see if it has developed any damage. When the door latch button is pressed, it contacts the latch lever, which releases the door.
If the latch lever breaks, the whole door system becomes faulty. In this case, the best solution would be to replace the door latch lever. To do this:
- Unplug the unit from power.
- Remove the unit from the cabinet and place it on a sturdy surface.
- Open the door and remove the turntable and its support.
- Disassemble the area around the control panel to access the latch lever.
- Remove the broken latch lever and fit in the new lever.
- Assemble the control panel.
- Put the microwave back into the kitchen cabinet and secure it with screws.
- Open the door and place the turntable and its support back into the microwave.
- Restore power to the unit

Frequently Asked Questions
1. Does a KitchenAid Microwave Have a Door Switch?
Most Kitchenaid microwaves come with at least three door switches or sensors: the monitor switch, the primary switch, and the secondary switch.
The work of these door switches is to prevent the magnetron from energizing whenever you open the microwave’s door.
Switches and door latch in the Kitchenaid microwave are designed in a way that when everything works properly the switches don’t close at the same time as the interlock switches.

Your KitchenAid microwave stopped working because either it doesn’t have power or an internal component is broken.
The household circuit breaker may have tripped, the socket is defective, the power cord is faulty, or you may have forgotten to have the power cord properly plugged into a power outlet.
Speaking of inner components, your KitchenAid microwave may have stopped operating because the line fuse or thermal fuse blew because of excess current and heat respectively. It could also be that the main control board is dead, but it is a very rare scenario.

Your KitchenAid microwave’s door won’t close because there is loose debris stuck on the door, the door latch button is faulty, the door latch lever is broken or the torsion spring is broken.
