SOURCE: Kenmore electric stove heating element how to replace

A replacement is usually around $40. There are usually 2 screws holding the element in the back of the stove. Turn off the power and remove the element. There are usually only 2 wires. It really doesn't matter which goes where. Install the new element and see if it will shut off when oven reachers temp. If it continues to heat, there is another piece that needs to be replaced. If there is a contactor or relay replace it, If not the thermostat needs to be replaced. Sometimes when the element burns out it shorts to the ground and fuses the contacts forcing the element to stay on. Sometimes you actually have to turn off the power to the stove.
