Gas range shows Er02 and gas burners shut off shortly after ignition

Safety first: Turn off gas and power before accessing burner assemblies.

Steps:

• Observe flame: Light the burner and watch whether the flame properly envelops the thermocouple tip. Adjust the burner cap if needed.
• Clean thermocouple: Gently clean the thermocouple tip with fine steel wool to remove oxidation.
• Check connections: Under the cooktop, ensure the thermocouple nut is tight at the gas valve and that the wire is not kinked or damaged.
• Replace thermocouple: If the flame goes out as soon as you release the knob, replace the thermocouple for that burner.
• Gas valve: If a new thermocouple does not hold the flame, the safety gas valve may be defective and should be replaced by a qualified gas technician.

Warning: Gas work must comply with local regulations. If you are not licensed, use a professional.
