The Microwave is tripping the breaker !!! (Troubleshooting) 

THANK YOU! Everyone kept telling I was crazy for trying to fix our microwave and to just buy a new one. I spent $7 on the replacement part instead of $250 on a new microwave. Glad I saw the comment about the thermal switch being inaccurately diagnosed, but otherwise this was very helpful!

Exactly my problem/bad door micro switch. I’ve been holding on to cherry micro switches for years from my past line of work. Fit right in. Thanks for the info!!!!

When checking the second thermal switch, and you got no continuity, you said the switch was bad, and you were wrong. The second switch stays open until the microwave reaches a certain temperature and then it closes to prevent the oven from getting too hot.

Thanks I had a bad right side thermostat (I think that's what it's called). You made it easy to find.

Thanks for sharing your expertise. We'll done!

Great that you fixed the issue but what are those faulty parts called? If we dont know we dont know what to ask or look for in the hardware store

Isn’t the right bottom thermal fuse built purposefully not to have continuity ?

this the only video that shows it might not only be the door switches it can also be the 3 round black thermostat controls . TEST THEM ALL. Test the 20A tube fuses too.

Sr. Where did yuo buy the parts and switch??

So basically you replace the second thermostat which was good, and the door switch which was bad.

I have the same problem

One thermostat is open and other one should closed

2nd thermostat is normally open and closes to a certain temperature. You also didn't show that you've replaced the thermostat, why? Least you can do is make a follow-up video to rectify and prevent false information on RU-vid.
