JennAir Infinite Switch or Burner Control Failure

JennAir electric cooktop element heats only on high or does not regulate temperature (no error code)

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed infinite switch contacts, Shorted control knob shaft, Loose wiring at switch, Faulty electronic burner control

Safety: Turn off power at the breaker.

Symptom check: If the burner only works on high regardless of knob position, the infinite switch is likely stuck closed.
Access switch: Remove the back panel or control panel to access the burner switch.
Inspect wiring: Check for burned or loose wires at the switch terminals. Repair as needed.
Replace switch: Transfer wires one at a time from the old JennAir-compatible infinite switch to the new one, matching terminal labels, and reinstall.
