Hello, I need some help with my microwave. Today when heating popcorn I got a sensor error and a very annoying beeping sound. Well come to find out everything seems to be working perfect but no heat, the turntable spins, blower works, etc.. I've done some searching on the internet and I've read it could be a thermostat or a magnatron (10 year warranty) How should I go about diagnosing it? I removed the microwave from the cabinets and pulled the covers / checked the fuses, no luck.
