How to Fix / Troubleshooting
Safety first: Turn off power. The thermostat is connected to live circuits.
Thermostat replacement:
- Remove the control panel and locate the thermostat behind the temperature knob.
- Carefully trace the capillary tube into the oven cavity and note its routing and clip positions.
- Disconnect wiring from the thermostat, remove mounting screws, and gently withdraw the capillary bulb from the cavity.
- Install the new Ilve thermostat, routing the capillary exactly as original and securing with clips away from elements.
- Reconnect wiring and test temperature with an oven thermometer.
