Our microwave shut down and will not turn on. I tested the fuses and the two sensors. One of the sensors (KSD-40LC) did not have continuity. Can that be the problem or are there other tests I can do?

Over the range microwave. Intermittently shuts down (loses power). Power comes back (sometimes) when door is jiggled. After removing the cover I found a sensor on top whose connection was burnt. Bypassing the sensor allows the microwave to work correctly. The sensor has the number KSD-120LC stamped on it. I think it is AP4220155. Just want to confirm. Thanks.

There are two thermal fuses (thermostats). One checks good (shows continuity). The other shows open, which has markings ksd 40lc. I saw you gave the part number to that thermostat as de47-20059b, (in q/a section). I orderded that number, but on the part, it is marked ksd 120lc. What is the difference between 40lc and 120lc in terms of temperature and characteristics? By the way, I checked the markings on the other fuse (good fuse) and that reads ksd 120lc. If I replace 40lc with 120lc, will it work? Are these both normally closed? Thanks
