GE XL1800, need help identifying Thermostat fuse and if it is the iss

Hi, GE XL1800 doesn't power on. Did continuity test for all fuses.

ANSWERS:

@frenchmanfl okay so you have a few T.C.O' (Oven Thermal Cutout) All TCO's are normally closed but it the bottom TCO were to open the MW would be totally "dead". Check it with an ohmmeter for continuity. That is the one that is my prime suspect at this point . See if this document will help GE-Spacemaker-XL.pdf Slightly different model but identical principal

"Old thread but I was wondering if you fixed your microwave?

Usually thermostats are closed (they let the current going through). This particular blue painted maybe be the fan control. It is normally open (circuit is broken) until it reaches a certain temperature (40C or so) then it closes and the fan kicks in. To test it, you have to warm it up a bit then use a voltmeter in Ohm position. It should read a resistance then.

Hope that helps."
