I have a model no. FPBM3077RFB Frigidaire microwave
Microwave kept popping the breaker, then stopped working all together. So I took it all apart and checked for continuity in all the fuses, and the door switches. Everything checked out besides the thermostat fuse ( KSD1 40/70) (no continuity between the terminals) so I bought another one that was described as a "Frigidaire Microwave Transformer Thermostat" and says KSD 130 on the back, tested it and it was good. I also replaced the blown fuse 20amp 125v with a 20amp 250v replacement. I double checked my connections, I checked the fan fuse for continuity with my multimeter and its good. The microwave runs great now, operates as if normal but the fan wont turn off.
The fan will adjust from high, medium, and low, but once i press the off button it still stays on a low mode. I have no idea what to do from here? Any help appreciated. Thank you!
