If your KitchenAid wall oven is producing a burning smell, stop using it and disconnect power if you suspect an electrical burning smell. The most likely cause is a defective temperature control thermostat, which regulates broiler temperature and may prevent the broil element from heating correctly. Next, a faulty oven control board or main control board may have damaged relays that fail to send voltage to the heating components. A burned-out bake element is another common cause of a burning smell from the oven. Inspect it for holes or blisters, and test it for continuity with a multimeter. Check the broil element the same way, since visible damage or no continuity indicates replacement is needed. On an electric KitchenAid wall oven, loose power cord connections at the terminal block can overheat, burn the connectors, and melt wire insulation. Do not operate the oven if the terminal block or wiring is damaged. Enter your model number to find the exact thermostat, control board, bake element, broil element, or terminal block replacement part for your specific KitchenAid wall oven.
01 - KitchenAid Range/Stove/Oven Temperature Control Thermostat
The temperature control thermostat regulates the broiler temperature. If the thermostat is defective, it may fail to heat the broiler element. The oven thermostat is not repairable—if the thermostat is defective, you must replace it.

The control board has relays that send voltage to the surface element circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
03 - KitchenAid Range/Stove/Oven Main Control Board
The control board has relays that send voltage to the surface element circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.
The broil element may have burned out. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.
If the power cord connections in the terminal block on your electric range are not secure the wire can overheat, burning the connections on the terminal block, and melting the coating on the wires. Check to ensure the connections are tight and not burnt. If the terminal block connectors are burnt, the terminal block should be replaced. If the power cord terminal connectors are burnt or damaged, the power cord should be replaced. If the power cord prongs are burnt, a new power cord should be installed and the receptacle checked and replaced if necessary by a licenced electrician.
