![]() To my chagrin, I discovered that this is a one-time, non-resettable switch. That's what prompted me to go searching online for a new switch and found this thread. However, the switch would not reclose even after cooling to room temperature. So when I followed the same method, the meter kept beeping until the switch got hot, the loud click sounded, and the meter went silent. The next temperature switch (the exact one mentioned in this thread) I checked the same way, but this one was NC (normally closed). I had to wait a surprisingly long time for the switch to cool down and reopen, but it did. Since it was an NO (normally open) switch, the meter was silent until I heard a loud click in the switch followed immediately by the beep of the meter. I checked one temperature switch by placing it on a hotplate burner while contacting the spade connectors with my multimeter set to beep for continuity. I was just checking the parts in my microwave as long as I had it open (the magnetron was clearly burnt). Hi All, I know this is a very old thread, but I found it useful, and I believe I have a solution to the problem of this "non-resettable" fuse.and so I post anyway. I am not sure what the part number refers to, if NT101 KIE is enough to go on, or if other brands exist, and what Nindicates. I see tons of sensors/thermistor oven cut offs for sale at various online repair shops but none match the model number. How am I supposed to understand what the numbers mean and if I can find a compatible component? The microwave is an old GE Model JES1142SMC 01 (manufacturing date July 2007). Therefore I need to simply change this sensor but the part is impossible to find. Anyways, after shorting across this sensor the microwave powered on, display was good, all ok. Either this is using non-resettable or it was damaged too far to go back. Manual said it opens at 212 F and closes at 32 F. I stuck it in the freezer, it did not click back. Checked continuity on the thermal cutout or "flame sensor" and it was open. As far as I reckon it went bad when his wife tried cooking for 20 minutes straight and there is no other flaw that caused this to get damaged. Hi, I'm helping to fix a friend's microwave and isolated the problem to the cavity TCO (it is labelled NT101 KIE on one side, and Non the silver cap side). ![]()
