4055538880 Genuine Semi Rapid (SR) Burner Cap Matt Black Enamel for Electrolux Gas Cooktops

4055538880 is a genuine Electrolux burner cap for the semi rapid (SR) burner on Electrolux group gas cooktops, finished in matt black enamel. The cap sits on top of the burner head and spreads the flame evenly around the ports. Cooktops usually have burners of several sizes, so make sure the cap you're replacing is on a semi rapid burner, and match the part number to your parts list.

Uneven flame or yellow tips? Check the burner cap

The burner cap closes off the top of the burner head so gas leaves only through the ports around the edge. If the cap is chipped, warped, cracked through the enamel or not sitting flat, the flame can lift, burn unevenly, go yellow, or fail to light all the way around. A missing or wrong size cap can also stop the ignition and flame safety from working properly. Caps that have been dropped or scrubbed with harsh abrasives are the usual candidates for replacement.

Seating the new burner cap

Turn every burner off and let the cooktop cool. Lift off the trivet, remove the old cap and wipe the burner head clean, making sure the ports are clear. Set the new cap down so it sits flat and centred on the head. Light the burner and check for an even blue flame. If it won't light or the flame stays uneven, have a licensed gas fitter inspect it.

Questions about this part

How do I tell which burner is semi rapid?

On many four burner cooktops there are two medium sized burners alongside the small auxiliary and the large rapid or wok burner, and these are usually the semi rapid ones. Your parts list will confirm which cap fits each position.
