The spark module sends high voltage to each igniter. When it fails, burners stop clicking or click continuously, and the fault is often shared across all burners rather than one.
Appliance part
Infinite Switch
The infinite switch cycles power to an electric element to hold a heat setting.
A failed switch can leave the burner on full, dead at every setting, or stuck on when the knob is off.
Symptoms of a failed infinite switch
- Burner only works on high
- Burner does not heat at any setting
- Burner stays on with the knob off
Fitment
Switches are matched by voltage, amperage and shaft style; confirm the model before ordering.
Before you buy
Confirm the model and serial plate before ordering — two parts can look identical and still not fit. If you would rather not fit it yourself, request a repair quote and we will route it to an independent technician.

Coil elements plug into a receptacle under the drip pan. They fail open or shorted, and a burned receptacle can take a new element out with it, so inspect both before replacing.
