Found a service manual on-line, and read some blogs that indicted the Thermal Cut Out devices that are basically thermal fuses. I removed the device from over the range, which turned out to be not 100% necessary, but made the repair much easier. Found that the Cavity TCO was certainly burnt, and tested bad with an Ohmmeter. The Hood TCO tested open, so I assumed that device was bad, which turned out not to be true. The TCO's are one shot, so I found PartSelect in a search engine, and entered my product model number. The parts were all clearly identified, so ordering was easy. Replaced the parts, bench tested the repair and re-installed the device. Way cheaper than a service call and I also replaced the long burnt out vanity light. This bulb burnt out in less than a year, but a serviceman had told me that the entire device had to be dis-assembled to replace the part, which is not true. This part can be replaced without removing the oven from the over-the-range mount, as can the three TCO's in the oven.
