2 out od three isn't bad
November 21, 2021

I ordered all three microwave interlock switches from the schemitic on Sears websight. the new top switch had a rted switch lever and the bottom two had tan switch levers. The top switch was different than the two botton switches. After replacing all three switches (all having Tan switch levers), when I shut the door the light and fans came on when the microwave was supposed to be off. Had to take it all apart again. I used one of the old switches (tan switch lever)and took out the new one with the red lever. . The microwave worked like it should. In other words all three switches should be the same part number or the new top switch was no good. But in either case I bought a switch that should have worked but didn't.

Exactly what was required!

Far Cheaper and Easier than buying and installing a new overhead-range-type microwave oven. There are multiple YouTube videos which explain the replacement procedure. If your microwave is turning on as soon as you open the door, this is probably the part needed for the repair.

Easy fix. My fan in my microwave over the stove would come on every time we open the door. Replaced the switch. Took seconds to do. High quality part. Very satisfied. Thank you Sears!

The microswitch was direct replacement for the original switch. The oven had to be removed from the wall as it is located above the range.
