Googled the problem and found Oven Temperature Sensor and Main Terminal Block to be the most likely problems. Turned out to be neither. No parts were needed. Oven has a thermal overload switch on the rear upper left. Thermal overload needed re-set. To do so you have to remove the oven, remove the back and press the red button on thermal overload. Biggest challenge was figuring out how to remove the oven. Even with the installation manual it was not easy to fgure out. The instructions are misleading. You need a special tool. I used two hacksaw blades as a substitute, and slid them in to release the clips. Once you figure out how to get the oven out the rest is simple.
