If your Frigidaire wall oven has a burning smell from the oven, stop using it until you identify the source. The most likely cause is a faulty temperature control thermostat, which can improperly control the broiler and overheat components. Next, inspect the oven control board and main control board. Failed relays may send incorrect voltage to the heating components, creating an electrical burning smell. A damaged bake element or broil element is also common. When working correctly, each element glows red hot, so look for holes, blisters, or other visible damage, then use a multimeter to test for continuity. If an electric Frigidaire wall oven has loose or burned wiring at the terminal block, the connections can overheat, melt wire insulation, and produce a burning odor. Turn off power at the circuit breaker before inspecting wiring, and have damaged electrical connections evaluated by a qualified electrician. Replace any defective thermostat, control board, main control board, bake element, broil element, or terminal block with the correct part. Enter your model number to find the exact replacement part for your specific Frigidaire wall oven.
01 - Frigidaire 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 - Frigidaire 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.
