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.
The schematic diagram, provided when pulling off the user touch pad, might as well be in an alien language because it doesn't help a novice like myself.
After researching possible causes of complete power outage, I ascertained (which makes sense) that it was likely a fuse issue. I started by conducting continuity tests of the traditional tubular fuses (both checked out fine) I then tested the two immediately accessible thermostat fuses. On is on the floor, in the component cavity behind the circuit board, when removing the microwaves touch pad control panel and one is located on the "back wall" that is parallel to the circuit board.
The fuse on the floor had continuity but the "back wall" fuse had no continuity. Aha, I thought, this is the problem child. Then after researching I was informed that there are thermo fuses that are closed, non continuous. The only identifier on this fuse was KSD-40LC & AC 250v/10A - AC125v/15A
So, color me lost. I found a couple of responses to no power and searched countless youtube videos. No one confirms why one thermostat fuse would be closed and that I should look at the diagram behind the touch pad, which I have done.
They are called TCO One is cavity, magnetron, hood, bottom. The drawings do not offer any physical representation that I can decipher. I have also looked into repair manuals ut they are only downloadable with subscriptions. Repairs are fortunately infrequent for me.
So, might a kind soul be able to advise why a thermo fuse might remain closed, intentionally? If this fuse sounds like it fits the "closed" bill? If so, could it be the problem? and if so, might anyone be able to help me narrow it down to a specific type so that I can order the correct part?
Honestly, these fuses aren't expensive so it isn't about the money so much as it is about trying my best to narrow it down so that time isn't wasted. My wife can't live without it. =) Thank you all for reading and for your very kind assistance.
