✅ Cross Reference Information
Common Symptoms
- Dual burner does not heat.
- Dual burner remains on high or does not respond properly to the control setting.
- Surface-element temperature is erratic.
- Only one portion or size of the dual element operates when the control is selected.
- Burner will not turn off.
Check Before Replacing
- With the range unplugged or the range circuit breaker switched off, confirm that the control knob is properly seated and engages the switch shaft.
- Compare the affected element with another element of the same size, if the range design permits; if the problem follows the element, the element may be involved rather than the switch.
- With power disconnected, inspect the switch and its wiring for loose, discolored, or heat-damaged connections. Do not probe energized terminals unless qualified to perform electrical testing.
- If the element remains energized, will not heat, or has erratic heat control after basic checks, use the model-specific wiring diagram or have the circuit diagnosed by a qualified technician.
