The part(s) or condition(s) listed below for the symptom Stove turns off on its own are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
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.
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.
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.
Inspect the wiring and connectors, especially coming from the main power cord. A loose connection can cause intermittent power failure. Inspect the wiring for breaks or burn marks. Repair wiring as needed.
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.
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.
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 control panel is faulty and should be replaced.
If a stove turns off on its own, check to see if the appliance's terminal block connections are burnt or melted. If so, the terminal block should be replaced with a new one.
If the stove surface element does not start working again when the surface element switch or control is turned off and back on or to a different heat setting, it's likely the radiant surface element itself is defective and should be replaced. You can use a multimeter to test the element for electrical continuity to confirm the diagnosis.
A stovetop surface element turning off on its own could be caused by a faulty surface element switch. Try turning the element switch all the way off then back on to a different heat setting. If the surface element begins working again, the switch is likely defective and should be replaced.
