Great value and got the job done. Our 4 year old GE microwave kept tripping the house circuit breaker each time the door was opened. They are a bit of a pain to install but well worth the time and expense of having to have a repair man come out buy a new microwave. These switches are all grey. The original are two blacks and a grey. Two are normally closed switches, black and one is normally open grey on the original... The switches are shipped with the normally open one marked NO in marker on the replacement switches. Just be sure to place the marked one in the grey switch slot on the o original.

Easy, cheap fix. Microwave's light would turn on, but no spinning or noise. There are three switches that communicate with the door being closed. Usually one of the will fail and the microwave will not detect the door being closed, so no spinning or heating. Simply as taking outer case off and swapping out the appropriate switch. Might as well just do them all while you're at it.

Sasaqutch's microwave is a fridgedare but many have the two locking switches and this one i used for the monitor citrcuit - you can actually disconnect the monitor switch and the wicrowave will work. One of the 3 switches will be bad and not switching - there is a fuse in the upper right just above the input panel with a screw 3 inches down inside throught the top to release the control panel and get to the switches. My monitor switch cause the microwave to stop working - only after many times just opening the door on 1 second left then it starts to do it at any time. Sasquatch says, "good luck"

My breaker would kick once I close the Microwave door. It turned out one of the switches had a bad button. I got those and they worked fine for me.

These were the exact replacement switches for my Kenmore microwave. The same manufacturer as the old switches. 2 normally open and 1 normally closed. No more blown fuse.

My microwave suddenly started tripping breakers and blowing fuses. Replacing these simple door switches fixed that. Absolutely worth the try if you are popping breakers with your microwave.
