Hi, this is Wayne from winnipeg-appliance-repair.ca. we’re going to talk about what to do if your wall oven won’t heat after you ran a self-cleaning cycle. The culprit in this situation is often a tripped thermal switch on the back of the oven. Most Kenmore, Frigidaire and Electrolux electric wall ovens have this safety switch to keep them from overheating. The problem is that this switch sometimes trips when you self-clean the oven because of the high temperature used during that cycle.
The self-clean cycle heats the oven to 800 degrees to burn off spills and residue, which the thermal switch can mistake for overheating. If this happens, you can reset the thermal switch by pressing this red reset button. Pressing the button is easy.
Getting to the back of the oven is a bit harder.
Disconnecting power to the oven by shutting off both circuit breakers. Most oven circuit breakers are double breakers, like this. Open the oven door.
Remove the mounting screw that secures the oven to the right side of the cabinet. Repeat the process to remove the mounting screw from the left side of the oven.
Some models use brackets like these to hold the oven in place.
In that case, you won’t see mounting screws.
If your oven has these brackets, use this special tool to release the mounting brackets. With someone’s help, carefully pull the oven out of the cabinet and rest it on a sturdy worktable.
Remove all of the screws that secure the back panel to the oven frame. Support the panel as you pull out the last screw to keep it from falling. Lift and remove the back panel from the cabinet. Here’s that thermal switch. Press the red button to reset it.
Before you put the oven back together, take a look at the wiring and make sure none of the wires are broken or damaged. This article explains how to repair wires in an oven correctly. Reinstall your oven in the cabinet and restore power. See if the oven heats.
If it does, you’ve probably fixed the problem.
Keep in mind that repeated tripping of the thermal switch will weaken this component. Replace the thermal switch if it won’t reset or if it trips repeatedly during normal oven operation. Here’s a article explaining you how.
Keep an eye out for burned cookies to make sure that oven’s not overheating. If the oven overheats in the normal baking mode or doesn’t heat after resetting the thermal switch, then you’ll need to have a service technician examine the oven and repair the problem.
