Ilve Hot Surface Sensor or Switch Stuck Closed

Cooktop hot surface indicator stays on even when cool

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 hot surface thermostat on element, Shorted indicator wiring, Faulty indicator circuit on control board

Safety: Disconnect power before testing sensors.

Allow full cool-down: Ensure the cooktop has been off for several hours and is completely cool to the touch.
Identify zone: Determine which zone's use triggers the indicator. That element's sensor is likely faulty.
Access element: Lift the cooktop and locate the hot surface sensor or thermostat attached to the element.
Test sensor: With the cooktop cool, test the sensor for continuity. It should be open when cool. If closed, replace the sensor or element assembly (depending on design).
