Help! I can’t get my range to turn off!

While it may seem a bit irregular, stovetop heating elements have been known to get stuck in the high position. If that is the symptom your range is experiencing, there is no need for further troubleshooting. The infinite-heat switch is your problem and should be replaced.
A range that uses single-coil surface heating elements is controlled with a rotary infinite-heat switch.  An infinite switch has no stops between the warm and hi settings. The stops are unnecessary because an infinite number of heat settings are available between the two levels. The switch is designed to send the electrical current to the surface element.
Inside the switch are two metal arms that help control the amount of current by opening and closing the circuit. Sometimes the switch malfunctions and the circuit becomes stuck in a closed position.
No matter where you set the desired temperature, the element will be stuck on high. This problem is usually solved by replacing the infinite-heat switch.
The following repair is for a Kenmore electric range but will be found to be adaptable to most electric ranges.

Safety First

  • Remember to unplug your range from its power source before working on it.

How to Remove the Infinite-Heat Switch

  • Remove the control knobs. If the knobs are difficult to remove, try using a rubber band or piece of sturdy string to pop them off their cams.
  • Remove the knob retainers that help hold the switches in place.
  • Remove the top panel.
  • Remove the screws holding the control bracket, lift and set aside.
  • Remove the two screws holding the switch you want to replace.

How to Replace the New Infinite-Heat Switch

  • Hot Tip: Only remove one wire off at a time from the old switch and plug into the corresponding terminal on the new switch.
  • Slide cam into the appropriate hole and replace the two screws that hold the new switch in place.
  • Return the control panel and secure with its screws.
  • Realign the top panel and replace the screws.
  • Replace the control knobs.
The repair is complete. All you need to do now is plug the range back into its designated electrical outlet and test your work.
