Burner cannot be adjusted and remains at full power regardless of dial position — the infinite switch has lost its ability to regulate current.
One or both heating zones on the dual-element burner produce no heat at any setting, indicating internal switch failure or open circuit.
The hot surface indicator stays illuminated after the burner is switched off, signaling the switch is not breaking the circuit properly.
Burner temperature fluctuates unpredictably or does not respond to dial changes, caused by worn internal contacts or a failed variable resistor inside the switch.




💡 Pro Tip: Is Your Infinite Switch the Culprit?
Your part is likely the culprit if you notice any of the following:
⚠️ Burner stays locked on HIGH and cannot be turned down
⚠️ Burner produces no heat at any dial setting
⚠️ Hot surface indicator light remains on after burner is turned off
⚠️ Erratic or inconsistent heating — temperature jumps between settings without input
Before replacing, use a multimeter to test the switch for continuity: with the switch OFF, check L1 to P — if continuity is present, the switch is defective. Also inspect terminals for burn marks or cracked housing as visual confirmation of failure.
