Etna oven produces excessive smoke or burning smell during normal cooking.

Safety: Ensure good ventilation. If smoke is heavy or acrid, turn off the oven and investigate.

• Initial burn-in: For new ovens, run an empty cycle at high temperature (e.g., 250°C) for 30–60 minutes with good ventilation to burn off residues.
• Clean cavity: Remove racks and clean grease from the bottom, walls, and elements using oven cleaner suitable for your Etna model.
• Check temperature: Use an oven thermometer to verify the oven is not overheating beyond the set temperature.
• Thermostat/sensor: If the oven overheats, test and replace the thermostat or sensor as needed.
