Gas oven will not ignite; no flame and no heat, but control appears to function

Safety first: Turn off electrical power and close the gas shutoff valve before working on gas components. If you smell strong gas, ventilate the area and contact your gas supplier immediately.

• Verify gas supply: Ensure the manual gas shutoff valve to the range is fully open and that other gas appliances in the home are working.
• Observe ignition: Restore power, set the oven to bake, and look through the oven window or remove the bottom panel to see if the igniter glows. If it does not glow at all, the igniter or its circuit is likely faulty.
• Test igniter: With power OFF, inspect the hot surface igniter for cracks or damage. Measure resistance; an open circuit indicates failure. Replace with the correct La Cornue igniter for your burner type.
• Check wiring and valve: Inspect the harness from the igniter to the gas valve and control. If the igniter glows but the burner never lights, the igniter may be too weak to open the gas valve or the valve itself may be defective. Replace the igniter first; if the problem persists, have a technician test and replace the gas valve.
