LG Electric stove burner won't turn off
When your LG electric stove burner won't turn off, the surface element may still be receiving continuous voltage even when the control is set to Off. Start by inspecting the control knob, since a damaged knob may not rotate the surface element switch stem far enough to disconnect power. A cracked or broken knob can also prevent the switch from reaching the Off position and should be replaced. If the knob is intact, the surface element switch is the next likely cause. Its internal contacts may have fused together, allowing the coil element to remain energized. On LG ranges with touch controls, a faulty oven control board, control panel, or touchpad may send constant voltage to the burner. Finally, a shorted surface element board or damaged wiring can keep the element on. If your electric stove burner is not turning off, switch off the range's circuit breaker immediately and avoid using it until the problem is repaired. Enter your LG range model number to find the exact replacement knob, surface element switch, control board, control panel, or surface element board for your appliance.
01 - LG Range/Stove/Oven Knob
If a range's surface element won't turn off, you should first inspect the control knob for damage. A broken knob may be unable to rotate the surface element switch stem to stop voltage being sent to the element.

02 - LG Range/Stove/Oven Surface Element Switch
The surface element switch sends voltage to the surface element coil. Sometimes, when the surface element switch fails, the electrical contacts inside the switch fuse together, causing the switch to send continuous voltage to the surface element. If the surface element switch is defective, replace it.

03 - Broken or cracked control knob
If the control knob is cracked or broken it may not be turning the stem on the switch. Inspect the control knob and confirm the switch is in the off position. If the control knob is damaged, it will need to be replaced.

04 - LG Range/Stove/Oven Oven Control Board
On some range models, the control board provides voltage to all of the appliance's electrical components. If the board is defective, it might send continuous voltage to a surface element even after the element has been turned off. If you've confirmed the surface element itself has not shorted and the element is controlled by a touchpad, it's likely the control board is faulty. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance's wiring diagram.

05 - LG Range/Stove/Oven Control Panel
A range's control panel can allow the user to select the heating functions for both a stovetop and an oven. If the control panel is defective, one or more of the buttons may have shorted and you will not be able to turn off the element. If you've confirmed the surface element itself has not shorted and the element is controlled by a touchpad, it's likely that touchpad or control panel is faulty.
Highly Likely
06 - LG Range/Stove/Oven Surface Element Board
If a range's surface element is controlled by a touchpad, it's possible the surface element board has a shorted component that is sending continuous voltage to the element. You can inspect the board for signs of burning or a shorted component. If the surface element and wiring are not shorted it is likely the surface element board is damaged and will need to be replaced.
