Ilve Flame Failure Device / Thermocouple Fault

On dual-fuel Ilve ranges, the gas oven burner will not stay lit or goes out shortly after ignition.

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

Weak or misaligned thermocouple, dirty burner ports, low gas pressure, faulty flame failure valve

Safety first: Turn off gas and power. Gas work must comply with local regulations; often requires a licensed gas technician.

Basic checks:

Clean the oven burner and ports to ensure an even flame that fully envelops the thermocouple tip.
Ensure the thermocouple tip is correctly positioned in the flame.
If the flame goes out as soon as you release the knob, the thermocouple may be weak; replace it.
If a new thermocouple does not resolve the issue, the flame failure valve may be defective and should be replaced by a qualified technician.
