This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty gas control valve, Blocked main burner orifice, Low gas pressure, Tripped high limit/ECO

Safety: Turn gas control to OFF and shut off gas supply before removing burner components.

Verify pilot: Confirm the pilot is strong and stable.
Inspect burner: Remove the burner assembly and check for rust, debris, or spider webs in the burner ports and orifice. Clean with compressed air.
Check ECO: On models with a separate ECO, verify it has not tripped. Replace if open and not resettable.
Gas control: If the burner still does not light, the gas control valve may be defective and should be replaced by a qualified technician.
