Uneven flame on the big burner? Check the cap

The burner cap sits on top of the crown and spreads the gas evenly out through the ports, so the flame forms a neat ring. A cap that's chipped, warped or worn through its coating won't seat properly. You'll see flames lifting on one side, yellow tips, a burner that's hard to light or keeps going out, and soot on the bottom of pans. Caps also get lost or swapped between burners during cleaning, which upsets the flame. Make sure the right size cap is on each burner before suspecting anything else.

Seating the new burner cap

Turn the gas off at the control knobs and let the burner cool. Lift off the old cap and clean the crown and ports with a soft brush, keeping water away from the ignition electrode. Sit the new cap squarely on the crown so it's level and doesn't rock. Light the burner and look for a clean, even blue flame. If problems continue, have a licensed gas fitter look at it.

Questions about this part
