Troubleshooting thermal switch problems on a wall oven.

If your Kenmore, Frigidaire or Electrolux wall oven won’t heat after you run the self-cleaning cycle, the thermal switch might have tripped. Most Kenmore, Frigidaire and Electrolux electric wall ovens have a safety switch—called a thermal switch—on the back of the appliance that trips if temperatures in the oven get too hot.

Sometimes, the self-cleaning cycle in your oven can accidentally trip the thermal switch because it uses high temperatures to burn off grease and food residue. It's easy to reset the thermal switch, but getting to it is a bit trickier. Watch this video to see how to get to the switch, reset it and get baking again.
