4055997730 Genuine LPG Gas Injector Nozzle 0.72mm for Auxiliary and Semi-Rapid Burners, Electrolux Group Gas Cooktops

This genuine Electrolux injector nozzle, part 4055997730, is sized 0.72mm for LPG and suits the auxiliary or semi-rapid burner positions on Electrolux group gas cooktops. The injector is the small jet that controls how much gas enters the burner, so its size has to match both the burner and the gas type. Check the size stamped on your old injector and the gas type on the cooktop's data plate before ordering.

Why the correct gas injector matters

Each burner on a gas cooktop has an injector with a precisely drilled hole. Gas pressure pushes fuel through that hole and the burner mixes it with air to make a clean blue flame. An injector that's too large for LPG gives tall, yellow, sooty flames, while one that's too small gives weak flames that may go out. Blocked or damaged injectors cause lazy flames, burners that won't light properly and slow cooking. Injectors are also changed when a cooktop is converted between natural gas and LPG.

Licensed gas fitter required

Changing a gas injector is work for a licensed gas fitter only. They'll isolate the gas and power, remove the burner parts to reach the injector, fit the new one with the right tool, then leak test and check the flame picture. If the cooktop is being converted to LPG, the fitter will also set the simmer adjustments and update the conversion label.

Questions about this part

Can I use this injector on a natural gas cooktop?

No. Part 4055997730 is an LPG injector. Natural gas burners use larger injectors, and fitting an LPG size on natural gas would starve the burner of gas. A licensed gas fitter should confirm the right injector for your gas type and burner.
