If your Americana wall oven has a burning smell, stop using it until you identify the source, especially if you notice an electrical burning smell, smoke, melted insulation, or scorching. The most likely cause is the temperature control thermostat, which regulates broiler temperature and may malfunction or overheat. Because this thermostat is not repairable, replace it if testing confirms failure. Next, check the oven control board and main control board. Their relays control voltage to the heating components, and a failed relay can create excess heat or prevent proper control. Inspect the bake element and broil element for holes, blisters, cracks, or darkened areas. A damaged element may smell as it fails and should be tested for continuity with a multimeter. Finally, inspect the terminal block and power connections for loose or burnt wires, melted insulation, or scorched connectors. Disconnect power before inspecting or testing electrical parts, and have damaged wiring or the receptacle evaluated by a licensed electrician. Enter your Americana wall oven model number to find the exact replacement thermostat, control board, element, or terminal block for your appliance.
01 - Americana 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 - Americana 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.
