Etna electric range oven display shows F0 and beeps; oven may not start.

Safety: Turn off power at the breaker before accessing the oven cavity or rear panel.

• Locate sensor: Inside the oven, find the thin metal probe (NTC sensor) usually mounted on the rear wall.
• Check connection: Remove the rear panel and verify the sensor wires are firmly connected to the harness and control board.
• Measure resistance: Disconnect the sensor and measure its resistance with a multimeter at room temperature (typically around 1000–1100 Ω at 20–25°C; check Etna specs). An open circuit indicates a bad sensor.
• Inspect wiring: Look for cuts, burns, or pinched sections in the sensor wiring.
• Replace sensor: If resistance is out of range or open, replace the oven temperature sensor with the correct Etna part.
