LG Stove turns off on its own

When your LG stove turns off by itself, the problem is usually a failing touchpad, especially when some buttons respond intermittently or not at all. A damaged or loose power cord is another likely cause on an electric range. Inspect the terminal block and cord connections for looseness, overheating, burnt connectors, or melted insulation. A faulty control board may also shut the stove down, particularly if a surface element works again after you turn its dial off and back on or select another heat setting. Loose, broken, or burned wire connectors can cause intermittent power loss, so inspect the wiring from the main power cord. Less commonly, a failed relay board can interrupt power to the heating elements and other components, while a defective main control board may have loose connections or a bad relay. Disconnect power before inspecting electrical parts, and have an electrician replace a damaged receptacle. Whether your LG stove turns off by itself during cooking or the electric stove turns off by itself at random, enter your model number to find the exact touchpad, power cord, terminal block, control board, wire connector, relay board, or main control board for your range.

01 - LG Range/Stove/Oven Touchpad

If a stove turns off on its own, determine if some of the buttons on the touchpad respond intermittently or not at all. If so, it's likely the touchpad is faulty and should be replaced.

02 - LG Range/Stove/Oven Power Cord

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.

03 - LG Range/Stove/Oven Control Board

If the stove surface element starts working again when the surface element dial or control is turned off and back on or to a different heat setting, it's likely that the control board is the cause of the stove turning off on its own. You should confirm that the surface element control is functioning normally and the appliance's power cord and terminal block are in good condition before considering a control board replacement.

05 - LG Range/Stove/Oven Relay Board

Some ovens are equipped with a relay board. The relay board has several relays which control the electrical current to the heating element, and other components of the stove. If one or more of the relays on the relay board has failed, the oven may shut off. If the relay board is defective, replace it.

06 - LG Range/Stove/Oven Main Control Board

The main control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
