LG Wall oven is producing a burning smell

If your LG wall oven is producing a burning smell, unplug it or switch off the circuit breaker before inspecting it, especially if the odor is an electrical burning smell from the oven. The most likely cause is a defective temperature control thermostat, which regulates broiler temperature and must be replaced if it fails. Next, an LG control board or main control board may have a failed relay that sends power incorrectly or prevents the heating components from operating properly. A burned-out bake element or broil element can also cause an oven burning smell. Check both elements for holes, blisters, or areas that do not glow red during operation, then test them for continuity with a multimeter. On an electric LG wall oven, inspect the terminal block for loose or burned power cord connections, melted wire insulation, or damaged terminals. Replace damaged wiring or parts, and have a licensed electrician check a burned receptacle or power cord prongs. Enter your LG wall oven model number to find the exact replacement thermostat, control board, main control board, bake element, broil element, or terminal block for your appliance.

04 - LG Range/Stove/Oven Bake Element

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.

06 - LG Range/Stove/Oven Terminal Block

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.
