8583540139216 Genuine Rapid Burner Top Cap Black for Electrolux Group Gas Cooktops, Replacement Burner Cap for Uneven Flame

Part 8583540139216 is a genuine Electrolux burner top in black, made for the rapid burner on a gas cooktop. The rapid is the high output burner used for boiling and searing. Its burner top, or cap, sits on the burner crown and spreads the flame evenly around the ports. Replace it if the enamel has chipped, the cap has warped or it no longer sits flat.

Uneven flame on a gas cooktop burner

A burner cap has to sit level and centred on the crown for the flame to come out evenly from every port. A cap that's warped, cracked or missing its enamel can leave gaps, giving a lopsided or yellow flame, a burner that's slow to light, or flames that lift and lick up the side of the pan. Spills that bake onto a damaged cap make things worse. Caps also get swapped between burners after cleaning, which is worth checking before buying a new one, since each burner size takes its own cap.

Fitting the burner cap

Turn off all burners and let the cooktop cool before handling caps. Make sure the burner crown is clean and dry, with no blocked ports. Lower the new cap onto the crown and turn it gently until it drops into position and sits flat. Light the burner and check the flame is even, blue and steady all the way around.

Questions about this part

How do I know which burner is the rapid?

The rapid is normally the largest single-ring burner on the cooktop, bigger than the semi-rapid and auxiliary burners. Measure your old cap and compare it with your parts list if you're unsure.
