Rapid burner lighting badly or burning yellow

The rapid burner is the large, high output burner used for boiling and fast frying. Its cap sits on the burner head and directs gas out through the ports in an even crown of flame. Constant high heat, boil-overs and harsh cleaners wear away the enamel, and a cap that has been dropped can warp. A damaged cap may give a patchy, lifting or yellow flame, slow ignition, or flames that go out when a heavy pan is put down.

Replacing the rapid burner cap

With the burner off and cool, lift off the pan support and the old cap. Brush out the burner ports, wipe the head clean and let it dry before fitting the new cap. Check it sits flat and fully seated, then light the burner to confirm an even flame. Never force a cap into place or try to adjust gas parts yourself, as any gas work needs a licensed gas fitter.

Questions about this part

Is this the large cap or the small one?

This is the large 100mm cap for the rapid burner. Smaller burners on the same cooktop take different caps, so measure your old cap across the top before ordering to be sure you get the right size.
