On gas Bertazzoni ovens, burner ignites but goes out after a few seconds.

Safety first: Turn off gas and power before cleaning or adjusting burner components.

• Clean flame sensor: Gently clean the metal flame sensor rod with fine steel wool to remove oxidation.
• Check sensor position: Ensure the sensor is in the flame path when the burner is lit.
• Inspect ground connection: Verify that the burner and sensor bracket have a solid metal-to-metal connection to chassis ground.
• Ignition module: If the flame still drops out, the ignition control module may not be detecting flame and should be tested or replaced by a qualified technician.
