3540166018 Genuine Upper Burner Crown for Electrolux Group Gas Cooktops, Defendi Burner Flame Spreader Ring

Part 3540166018 is the genuine upper crown for a Defendi gas burner used on Electrolux group cooktops. The crown is the slotted ring the flame burns from, and this one sits on the upper level of the burner. We don't have a model list for it yet, so compare it closely with your old crown, or send your cooktop's model and PNC through the parts enquiry form and we'll confirm the fit.

When a gas cooktop burner crown needs replacing

Gas leaves the injector, mixes with air in the burner body and exits through the ports around the crown, where it lights into an even ring of flame. Over years of boil-overs and cleaning, crowns warp, crack or corrode, and the ports clog with burnt-on food. Typical signs are a patchy or yellow flame, flames lifting away from the ports, a burner that is slow to light or goes out on low, and a crown that no longer sits flat. A soft brush can clear blocked ports, but a distorted crown has to be replaced.

Swapping the burner crown

Turn off the gas supply to the cooktop and let the burner cool completely. Lift off the cap and the old crown, noting how the locating lugs line up with the burner body and the ignition electrode. Seat the new crown flat, refit the cap and check every burner lights to an even blue flame. If the burner body, injector or any gas fitting needs attention, call a licensed gas fitter.

Questions about this part

Will this crown fit any burner on my cooktop?

No. Crowns are made to suit a particular burner size and position, so an upper crown won't swap with one from a different burner. Check the crown you're replacing against 3540166018, or send your cooktop's model and PNC so we can confirm.
