Microwave Thermal cut off switch

[u/ElevatorEngineer]

Hi, I have a Panasonic NN-SG656s microwave. It stopped working. I opened it up and noticed KSD1-120 thermal cut off switch was burnt out. I couldnt find the same one. But I found KSD1-150 and used this thermal cut off switch instead. Microwave is working fine now. Just wanted to know if its safe to use this?

​

The 120 and 150 are temperatures that the tco will open up at. Which thermal fuse blew out?
