30401800054 Genuine Wok Burner Thermocouple for Glen Dimplex Group Gas Cooktops, Flame Failure Safety Thermocouple

Part 30401800054 is a genuine Glen Dimplex thermocouple for the wok burner on gas cooktops. The thermocouple is the flame failure safety device that lets gas keep flowing only while the burner is alight. Wok burners usually take a different thermocouple from the standard burners, and lengths and fittings vary between models, so confirm 30401800054 on your parts list or old thermocouple before ordering.

Wok burner won't stay lit?

The tip of the thermocouple sits in the flame. When it heats up it produces a tiny voltage that holds open a magnet valve in the gas tap, keeping gas flowing to the burner. If the flame goes out, the tip cools, the voltage drops and the valve shuts. When the thermocouple wears out or its tip is bent away from the flame, the burner lights while you hold the knob in but goes out a few seconds after you let go. Clean the tip and check its position before deciding the part has failed.

Part details

• Thermocouple for the wok burner
• Flame failure safety device
• Gas safety part, installation by a licensed gas fitter only

Installation by a licensed gas fitter

Gas safety devices must be replaced by a licensed gas fitter under Australian rules. Before work starts, the gas supply is turned off and the cooktop isolated from power. The fitter will route the new thermocouple along the same path as the old one, connect it to the gas tap without overtightening, position the tip correctly in the flame, then leak test and check the burner holds its flame.

Questions about this part

Can I fit this thermocouple myself?

No. In Australia, work on gas appliances, including flame failure devices like this one, must be done by a licensed gas fitter. They will fit it, check the connection for leaks and confirm the burner shuts off safely when the flame goes out.
