4055565248 Genuine Burner Thermocouple 275mm for Electrolux Group Gas Cooktops, Flame Failure Device

Part 4055565248 is a genuine Electrolux group burner thermocouple, 275mm long. It is the flame safety sensor that sits beside a gas burner and keeps the gas valve open only while a flame is present. If a burner lights but goes out as soon as you release the knob, a worn thermocouple is a common reason. Measure your old one and check your parts list for 4055565248.

Gas burner won't stay lit? The thermocouple may be worn

The thermocouple tip heats up in the flame and produces a tiny voltage that holds the safety magnet in the gas valve open. If the flame goes out, the tip cools and the valve shuts off the gas. Over time the tip burns away, gets coated in residue or is knocked out of position, and that voltage drops. You will notice the knob needs holding in for longer before the burner stays lit, or the flame goes out on low. Cleaning the tip and checking it sits in the flame can help, but a worn thermocouple should be replaced.

Replacing the thermocouple

In Australia, repairs to gas appliances must be carried out by a licensed gas fitter. The gas supply is turned off and power to the cooktop isolated before the thermocouple is unclipped at the burner and unscrewed from the valve. The new lead is routed the same way as the original, clear of hot surfaces, then leak tested and flame tested before use.

Questions about this part

Does the thermocouple length matter?

Yes. The lead needs to reach from the burner to the gas valve without being stretched or bunched up. This one is 275mm, so compare it with your old thermocouple and check your parts list shows 4055565248.
