Common Symptoms
- Triple burner stays on high despite a lower knob setting
- Heat level does not respond correctly to knob adjustments
- Triple surface burner does not turn on or does not heat
- Burner does not turn off when the control is set to Off
- Only part of the triple element operates
- Intermittent operation of the triple surface burner
Check Before Replacing
- With power disconnected, inspect the switch wiring terminals and harness for burning, looseness, corrosion, or heat damage.
- Verify that the control knob engages the switch shaft correctly and is not cracked or slipping.
- Compare operation with another appropriate surface element, if the appliance design permits, to help distinguish an element problem from a control-switch problem.
- Confirm the range has the correct electrical supply and that the circuit breaker is fully on.
- If the burner remains energized in the Off position, disconnect range power until the fault is diagnosed.
Pro Tip
A burner stuck on high or failing to regulate can also be caused by the radiant element, damaged wiring, a faulty knob, incorrect supply voltage, or an incorrect switch configuration; verify the triple-element switch and burner position before ordering.
