How To Fix A Cooktop Element That's Not Heating

Surface burners are typically either a coil type, solid type or a ribbon coil as used in smooth top ranges. All of these consist of a heating wire that uses electric current to produce heat. Coil type elements can be checked for continuity by removing them from the terminal block and testing them with a multi-meter. You should also inspect the terminal ends for signs of heat damage or corrosion, and if present, you should replace the terminal block or receptacle at the same time. You will need to remove power from the range to change the terminal block. Solid elements and smooth top elements require raising or removing the main top to gain access. You will need to remove power from the range before lifting the main top. Continuity can then be checked with a multi-meter, once you have removed the wires from the element terminals.

The burner receptacle or terminal block is used to connect coil elements to the internal wiring. The receptacle is located underneath the cooktop and is mounted to it by one or two screws. If the elements are not heating up then the receptacles may be faulty. Check the element terminals for signs of corrosion, arcing or overheating and, if present, replace both the terminal block and the element.

The infinite switch on the control panel controls the power to each element. If you have no heat at an element and the element and terminal block check ok, then you may have a defective infinite switch. Disconnect power to the range and remove the console back panel. Locate the switch and check for overheated wires or faulty terminals first. Test the switch’s contacts for continuity with a multi-meter. If defective, replace the switch. If the infinite switch does not appear to be defective, then you should check for proper voltage to the switch. This is a live high voltage test and should only be performed by qualified persons!
