Originally thought maybe a fuse but first thought to look on the internet. Found this website which was very helpful. Turned out the thermostat on top of the microwave was the problem. Ordered the thermostat and spares for the future. Replaced the thermostat and problem solved. This item is inside so the cover had to be removed. While removing the cover I found a wiring diagram inside the Display Module. It was helpful although I had to trace the wires to locate the thermostat. Turns out microwaves are not that complicated. Thanks AppliancePartsPros.com for your help

Replaced a thermocutoff devoice that was under the case and in contact with the top of the oven cavity. As an over the range vent\microve oven, the most difficult task was getting the oven unhooked from the vent tube and out of it's built in location over the range. Replacing the actual device didn't take more than a minute.
