Fagor Temperature Control / Infinite Switch Failure

Electric cooktop or range surface elements overheat or do not regulate temperature properly.

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

Stuck infinite switch contacts, Faulty simmer control, Shorted wiring, Defective electronic power regulator

Safety first: Disconnect power before accessing control knobs or internal wiring.

Identify affected element: Note which burner does not respond to knob adjustments.
Inspect switch: Remove the control panel to access the infinite switch for that element. Look for signs of overheating or burning.
Test switch: Use a multimeter to check continuity between switch terminals in different knob positions according to the wiring diagram.
Replace switch: If the switch is stuck closed or does not change state, replace it with the correct Fagor part.
