How To Take Apart A Microwave

Step 15 Thermal fuses

Sometimes, you can find an thermal fuse(s) in a microwave - often found near the magnetron. They are used to break the circuit from the mains if the magnetron overheats...

 I have two questions regarding thermal fuses:
At what temperature do they cut power?
And can they be reset after they trip?
I have acquired two from an old microwave and would like to put them to use.

The temperature at which they cut varies. However, they do reset after they cool down.

if they have a number on them, try googling it to find a datasheet

 Thank you, but I have solved the problem. There were no datasheets, but I happened across another microwave, and it included a schematic. It had the same thermal fuses, and the schematic told me the trip temperatures. Thanks for the tip, though!
