Manufacturer Part Number: W10211972

The Switch is an OEM part for Whirlpool microwaves. It controls the turning on and off of power to the microwave during cooking cycles as well as detects positions within cycles to signal appropriate actuations of the microwave's magnetron, fans, and lights. The switch is a crucial electrical component that facilitates the fully automatic operation of preset cooking programs.  

Causes of a bad switch can include wear and tear over time or unexpected surges that cause electrical component failure.

Symptoms of a bad switch include:

  • Cooking programs failing to advance properly or stopping mid-cycle unexpectedly
  • The microwave failing to turn on or experiencing power issues  
  • Random noises, humming, or lights occurring when the microwave is supposed to be idle
  • Buttons or controls acting intermittently unresponsive

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Julie, There is no way to trigger the latches to come back up and if they have gotten stuck in the down position they would need to be replaced.

Hello Stevie. It does sound like a door switch issue. Make sure the latches are good, and if so, test the switches. To access and replace them, you need to remove the microwave from the unit and remove the outer cover off the microwave. Then you can access the switches.

Rick, The issue would be with the monitor switch, You will want to make sure that the switch latch and the switch are making proper contact. If they are then you will need switch kit 4392027.

Suzette for Model Number KBMC14OHSSO3 - KitchenAid Microwave/Convection Oven

My built in KitchenAid Microwave/Convection Oven displays "door" when the START button is pushed. I'm guessing it's the door sensor but I don't know how to test it or which door sensor part is correct for my model. Also the light hasn't come on for a long time and I can't seem to unscrew it from the inside. How do I access the bulb and what bulb should I use? And lastly, there is no longer any door tension, which tension replacement part should I buy. Thanks so much - Suzette

Hi. On your microwave there are 2- latch assy. One on the left side, holder part # W10727408 and the one on the Rt side, holder part # W10727408. They have also the separate switch part # W10211972 that they use. The primary interlock "door" switch has one red, two browns and one black wire on the switch. You will need to remove the top to change the switch. The halogen light pulls out as it has 2 pins inserted into female sockets. Light part # WPW10440740. Thank You.

Mellisa, there are several possibilities, first open the door and check for both door catch tabs being present on the inner door liner closest to the control panel. If the catch tabs are there and operates properly, the issue will be in the door switches and door switch actuators, which may require removel of the microwave in order to access the actuators and switches, depending on the model number.

Hi Ken. Remove the power and disconnect the door switch wires off the switch part # W10211972. Then connect them together (temporarily) to see if the circuit completes now and the cavity light goes out. The Red,Black connects to the common of the switch and the brown wire and the blue wires feed the light transformer and the control board. This is the side of the switch/cam assy. you will need. I am unable to decipher by the parts breakdown which switch is what side so I will give you both. The lt. side switch/cam assy. is part # W10727408. The rt. side is part # W10727408. What is the rest of the model # after KEMC377..........? We will need this to help get the correct part #'s to you. Thank You.
