Dual burner cannot be turned down — switch contacts are fused or worn, locking output at maximum power regardless of knob position.
Front-left dual element produces no heat when switched on; switch has failed open and no longer sends voltage to the surface element coil.
Unable to toggle between the inner small element and outer large element; switch mechanism no longer routes power correctly between the two coils.
Burner cycles on and off unpredictably or temperature jumps between settings, indicating worn internal contacts inside the infinite switch.
Control knob spins freely or does not engage the switch shaft, resulting in no change in burner output even when the knob is turned.
💡 Pro Tip: How to Diagnose a Faulty Dual Element Control Switch
Your part is likely the culprit if you notice any of the following:
⚠️ Burner stays stuck on HIGH no matter what position the knob is turned to
⚠️ Unable to switch between the inner (small) and outer (large) heating element
⚠️ Burner produces no heat even when the switch is turned on
⚠️ Temperature knob feels loose, spongy, or does not engage properly
🔍 Diagnostic Tip: The surface element switch cannot be tested with a multimeter in the traditional sense — if swapping the element to another burner position still shows the same problem, the switch is the confirmed cause. Replace it directly. Never attempt to repair the internal contacts; always install a new switch for safe operation.
