If your LG electric stove burner is not working, the most likely cause is a failed surface element switch, which sends voltage to the coil or radiant surface element. If your LG range has another burner of the same size, switch the elements to help narrow down the problem. If the burner still does not work, the switch may need replacement. When two or more burners stop working at the same time, a defective surface element board is more likely because its relays regulate power to the burners. The range may also have an incoming power problem. LG electric ranges require 220 volts, so use a multimeter to check the voltage at the wall outlet. If only one burner is affected, inspect the coil or radiant surface element or radiant element for damage, confirm it is seated fully in the receptacle, and test it for continuity. A coil or radiant surface element without continuity has burned out and must be replaced. These steps can help diagnose an electric stove burner not working, a stove element not working, or one burner not heating. Enter your LG range model number to find the exact replacement part for your appliance.

The surface element switch sends voltage to the surface element coil. If the switch is defective, the surface element will not work. If there is another element of the same size on the stove, try switching the elements. If the surface element still doesn’t work, the surface element switch is likely defective. The surface element switch cannot be tested or repaired—if you suspect the switch is defective, replace it.
The surface element board has relays that regulate the power supply to the burners. If one or more of the relays fails, the surface element won’t work. If two or more burners fail at the same time, this indicates that the surface element board is likely at fault. If only one surface element won’t work, use a multimeter to test the element for continuity. If the surface element has continuity, the surface element board might be defective.
It is possible that the range is not receiving proper voltage. Electric ranges require 220 volts of alternating current. If the range is receiving significantly less voltage, the surface element won’t work. To determine if the electrical outlet has sufficient voltage, use a multimeter to test the incoming power at the wall socket.

First, make sure that the element is pushed all the way into the socket. Second, inspect the surface element for damage. If the element appears to be damaged, replace it. Lastly, use a multimeter to test the surface element for continuity. If the surface element does not have continuity, replace it.
The most common cause when the surface element won't work is the radiant surface element itself. The radiant surface element - or heating element - can burn out similar to a light bulb. If the surface element won't work and it doesn't have continuity, it will need to be replaced. The radiant surface element is not repairable.
