Lex for Model Number MCO165uw I mistakenly ran the microwave for some amount of time with nothing in it, I meant to set timer but i started the microwave, i know I set it for 15 minutes but I'm not sure how long it ran before it shut off. Once it shut off it initially would not show any indication of power. Then after about 30 minutes or so it mysteriously powered back up but if fails to heat now . Everything works , it just will not heat. all thermal fuses seem to be fine, ALSO .. how do i determine the state of the 2 thermal fuses behind the panel, mounted to the bottom ? NO . NC ??? i know one of them test with continuity and the other doesnt
Answer Lex, The 2 thermals behind the control panel one will be open and one will be normally closed. As for the heating issue you will want to check the magnetron to make sure that it is good and should have a resistance of less than one ohm to be good. Read More...
