Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):
This switch monitor interlock is a critical safety component designed to ensure proper communication between the microwave door latch and the control board. When functioning correctly, it confirms that the door is securely closed before allowing the microwave to operate. A damaged or faulty switch may prevent the unit from starting, even if the door appears latched. Replacing this genuine part restores safe and reliable operation. Installation should be performed with care, and it's recommended to disconnect power before beginning any repair.
How Buying OEM Parts Can Save You Time and Money
Why buy the real thing?
OEM stands for Original Equipment Manufacturer. Simply put, this means that the company who made your appliance is also supplying the replacement part for it.

repair straight forward...problem not fixed
The part arrived as scheduled in a couple of days....it matched the part in the unit. After replacing it however the unit started for a second or two and then just went dead...no lights, nothing. The outlet was still live...so not sure if the fuse in the unit blew or what happened. I have replaced all three switches and the unit does not operate...time to buy another one.

The power was on but the Microwave would not start.
This is an above the range microwave, use 2 people to remove it. I set it on a table and removed the outer cabinet. I then used jumper leads to discharge the capacitor. I removed the control panel (taking a picture to ensure proper wiring on assembly), then I removed the latch board. Once I had the latch board out I removed the monitor sw

I tested the other two switches as well and found these (normally open) switches for continuity to be good and the monitor switch to have a short. This switch should show continuity when the door is open and should show no resistance when the door is closed. (Take care removing the switches) After I received the parts I installed them in the new Locker Holder and installed the latch board (ensure to follow the latch board adjustment steps located in the control board). I then attached the wiring to the control board and then plugged in the unit. I tested the unit to ensure it functioned correctly. I then installed the outer cabinet, and then installed the unit above the range (Use 2 people for this process). Overall an easy fix you just need to ensure you follow safety procedures (especially when dealing with capacitors. Take a lot of pictures of the wiring and of the components and take care with the latch board or you'll have to buy a new one when all you really needed is a monitor switch.
Remove upper grill, then control panel, then 2 screws hold door switch mounting bracket, that will let you roll the switches out to work on them. Remove each switch by carefully pushing back retainer clips. Diode a long pair of needlenose pliers is helpful. The control board in front of capacitor comes out with a flat screwdriver and pry

Hello Richard, thank you for your question. Your fan may be slow due to a clogged Grease Filter PS1022452. Unplug it and clean the filter. If same after plugging it back in, you may need to replace the Control Board PS12296777. We hope this helps.
