4055529137 Genuine Thermocouple 400mm for Electrolux Group Gas Cooktops, Dual 5kW Burner Flame Failure Thermocouple

This is a genuine Electrolux thermocouple, part 4055529137, with a length of 400mm. Its description links it to a dual 5kW gas burner, the large multi-ring burner found on some cooktops. The thermocouple sits in the flame and keeps the gas flowing only while the burner is alight. Check the burner rating, the length and the number on your old thermocouple before ordering 4055529137.

Gas burner won't stay lit when you let go of the knob

A thermocouple produces a tiny voltage when its tip is heated by the flame. That voltage holds the safety valve in the gas tap open. If the flame goes out, the tip cools, the voltage drops and the valve shuts, so unburnt gas cannot escape. When a thermocouple weakens, the burner lights while the knob is held in but goes out as soon as you release it. A tip that is bent out of the flame or caked with spills can cause the same fault.

Having the thermocouple replaced

In Australia, gas safety parts like this are a job for a licensed gas fitter. Before they arrive, turn the cooktop off and let it cool. The fitter will isolate the gas, connect the new thermocouple to the tap, position the tip correctly in the flame path and test that the burner shuts off when the flame goes out.

Questions about this part

Can I use a thermocouple of a different length?

Length matters because the lead has to reach from the burner to the tap without strain or tight bends. Match the 400mm length and the 4055529137 number, and ask your licensed gas fitter to confirm the part if unsure.
