Ilve Gas Cooktop Error F3

DIY Fix Verify context and basic reset

1. If the appliance is part of a combined range with an oven, power off the appliance at the breaker for a few minutes and restore to see if the code clears.
2. Ensure you are referencing the correct model’s documentation — stand‑alone Ilve gas cooktops typically do not display oven sensor codes unless part of a range with electronic display.
3. Check that all knobs are in the correct position and no other error indicators are present.

Technician Only Inspect temperature sensing circuit (for range/oven models)

1. Disconnect power at the breaker before service.
2. Access the oven/combined unit’s temperature sensor and wiring harness.
3. Check sensor continuity with a multimeter; replace sensor if open circuit detected.
4. Inspect wiring and connectors for damage; repair/replace as necessary.
5. If sensor and wiring are intact but the F3 persists, inspect/replace the control board temperature sensor interface section.

Parts needed: Oven temperature sensor/NTC probe, Harness connectors, Control board (if required)
