Fortunately, my brother-in-law suggested it might be the "cut out" switch. After unplugging the microwave, I opened it up and identified one of two cut outs and removed the wires from each side of the cut out. To test if that was the problem, I connected the two wires together, bypassing the cut out. When I plugged the unit back into the wall socket, the lights came back on, and i ran the microwave for a few seconds. It verified that this was the problem. I ordered the part and when it arrived, I removed it with a philips screw driver and replaced it with the new one. I replaced the screw, buttoned the unit back up, plugged it in, and saved a few hundred bucks on a replacement microwave, and as important, saved our landfills and planet a tiny but.
