Electric Stove Burner Temperature is Erratic

Troubleshooting and Solutions

If your electric stove burner’s temperature is erratic, it can make cooking difficult and inconsistent. Here are some common reasons for erratic temperature control and steps to troubleshoot and fix the issue:

Common Causes:

  1. Faulty Infinite Switch:

    • The infinite switch, which controls the burner's heat levels, might be defective.
  2. Loose or Damaged Burner Element:

    • The burner element might be loose, damaged, or not making proper contact with the socket.
  3. Burner Socket Issues:

    • The socket that holds the burner element might be faulty or have loose connections.
  4. Wiring Problems:

    • There might be issues with the wiring connections inside the stove.
  5. Faulty Control Board:

    • The control board, which regulates the temperature settings, might be malfunctioning.

Troubleshooting Steps:

  1. Check the Infinite Switch:

    • The infinite switch controls the power levels sent to the burner.
    • Turn off the stove and unplug it from the electrical outlet.
    • Remove the control panel to access the infinite switch for the affected burner.
    • Use a multimeter to test the switch for continuity. If there is no continuity, the switch is likely defective and needs replacement.
  2. Inspect the Burner Element:

    • Turn off the stove and let it cool completely.
    • Remove the burner element from the socket and inspect it for any visible damage, such as burns, breaks, or blistering.
    • Ensure the element is properly seated in the socket. If the element is damaged, replace it.
  3. Check the Burner Socket:

    • While the burner element is removed, inspect the socket for any signs of damage or burn marks.
    • Ensure the prongs inside the socket are not corroded or bent out of shape.
    • If the socket appears damaged or the connections are loose, it might need to be replaced.
  4. Inspect the Wiring:

    • Check the wiring connected to the burner, socket, and infinite switch for any signs of damage or loose connections.
    • Ensure all connections are tight and secure.
    • Repair or replace any damaged wiring as necessary.
  5. Test the Control Board:

    • If the infinite switch, burner element, and socket are all functioning correctly, the control board might be the issue.
    • Turn off power to the stove at the circuit breaker.
    • Access the control board and inspect it for any visible signs of damage or burn marks.
    • Use a multimeter to test the board. If the control board is faulty, consider having it repaired or replaced.
