The main component involved with microwave heating is called the magnetron (I used to work on microwaves many years ago). Mine stopped heating after 10+ years, so my first suspicion is the magnetron. A replacement magnetron is over $125. I had already replaced the control panel a few years ago, and the door switch was getting janky, so the math led me to just gettting a a whole new microwave.
