Range: Surface element doesn't heat properly
When a cooktop heating element on an electric range fails to heat, the problem could be a failed surface burner element, a wiring failure or a bad infinite burner switch. If a burner element is on and can't be turned off or adjusted, the problem is usually a failed infinite burner switch.
These repairs may help solve your Range problem:
Replace the range radiant surface element
The radiant surface element is mounted on the underside of a ceramic glass cooktop. Replace the element if it fails to heat or has a faulty limiter.
Replace the range coil surface element
The coil surface element, also known as the coil element, plugs into the terminal block in an electric cooktop. It's controlled by a surface element switch (also called an infinite burner switch) and sits above a drip pan. It provides the heat for that location on the cooktop. Replace the coil surface element if it's physically damaged or won't heat.
Replace the range surface element switch
The surface element switch (also called a surface burner switch or infinite burner switch) is used to turn on the heating elements on an electric cooktop. If the switch's electrical contacts fail, the switch might not turn the surface burner on or off, or it might not control the heat level of the burner.
Replace the range relay control board
Some ranges have a relay control board that's separate from electronic control board. The relay board has electrical relays that control voltage going to major loads such as the bake element or a surface element, based on signals from the control board. Replace the relay control board if it fails to properly control voltage to a component.
Replace the range limiter on a radiant surface element
The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating. That limiter is included with the element on some radiant surface elements, while on others it can be replaced as a separate component. If a surface element fails to heat, or the limiter is not regulating the maximum temperature properly, replace it.
Replace the range solid surface disc heating element
A solid surface disc element is a solid metal surface element that's mounted on the top an electric cooktop or range for surface cooking. Ribbon heating coils under the solid metal disc transmit heat to the surface of the disc and then to the cookware. Replace the element if it doesn't heat up even when it’s receiving power.
