If the connections of the power cord in your electric range's terminal block aren't secure, the wire can get too hot. This can lead to burnt connections on the terminal block and melted wire coating. It's important to make sure these connections are tight and not burnt. If the connectors on the terminal block are burnt, the terminal block needs to be replaced. If the connectors of the power cord are burnt or damaged, you should replace the power cord. If the prongs of the power cord are burnt, a new power cord should be installed. Also, the receptacle should be checked and, if needed, replaced.
If a stove switches off by itself, try to see if some of the buttons on the touchpad sometimes work or don't work at all. If that's the case, it's probable that the touchpad is not working properly and needs to be replaced.
If the stove's surface element begins to work again when you turn the dial or control off and back on, or adjust to a different heat setting, it's probable that the control board is causing the stove to shut off by itself. Before thinking about replacing the control board, you should first check that the surface element control is working properly and that the power cord and terminal block of the appliance are in good condition.
If the stove's surface element doesn't begin to work again when you turn the switch or control off and back on, or change to a different heat setting, it's likely that the radiant surface element itself is faulty and needs to be replaced. You can use a tool called a multimeter to test the element and check if electricity can flow through it, which will help confirm the problem.
If a stovetop surface element switches off by itself, the cause might be a broken surface element switch. Try completely turning off the element switch and then turning it back on to a different heat setting. If the surface element starts working again, it's probable that the switch is not functioning properly and needs to be replaced.
Check the wires and connectors, particularly those connected to the main power cord. A connection that isn't secure could lead to power cutting out occasionally. Look for any wires that are broken or have burn marks. If you find any, they should be repaired as needed.
Some ovens come with a relay board. This board has multiple relays that manage the electric current going to the heating element and other parts of the stove. If one or more of these relays on the board stop working, the oven might switch off. If the relay board is faulty, it should be replaced.
The main control board is responsible for providing power to all parts of the stove. If the connections of this board are not secure, burnt, or if the board itself is shutting off independently, it's possible that one of the relays or other components is faulty. In this case, the control board will need to be replaced.
If a stove switches off by itself, try to see if some of the buttons on the touchpad sometimes work or don't work at all. If that's the case, it's probable that the control panel isn't functioning correctly and needs to be replaced.
If a stove switches off by itself, inspect the connections of the appliance's terminal block for any signs of being burnt or melted. If you notice such signs, the terminal block needs to be replaced with a new one.
