Ilve Selector Switch / Thermostat Shaft Wear

Control knobs on the oven are stiff, hard to turn, or do not click into positions 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

Grease or debris in knob shaft, worn selector switch detents, damaged thermostat spindle, melted knob from overheating

Safety first: Turn off power before removing control panel components.

Knob and switch checks:

Pull off the knobs and clean the shafts and knob bores with a mild degreaser; dry thoroughly.
Inspect knobs for cracks or deformation; replace if they no longer grip the shaft properly.
If the selector switch or thermostat is stiff internally, replace the switch/thermostat assembly.
Ensure the control panel is not warped and pressing against the knobs.
