CC40600Z Generic Thermocouple Kit 600mm, Universal Pilot Flame Thermocouple for Gas Appliances with a Standing Pilot

CC40600Z is a generic 600mm thermocouple kit for gas appliances that use a standing pilot flame. The thermocouple sits in the pilot flame and proves to the gas valve that the pilot is alight, so the valve stays open. This is a universal style kit, not tied to one appliance brand. Measure the old thermocouple and check how it connects to your gas valve before ordering, as both the length and the fitting need to suit.

Pilot light won't stay lit? Check the thermocouple

Heat from the pilot flame makes the thermocouple generate a tiny voltage. That voltage holds a magnet in the gas valve open, and if the flame goes out the voltage drops away and the valve shuts off the gas. It's a key safety device. When the tip burns out or the lead is damaged, the pilot will light while you hold the knob in but goes out the moment you let go. A pilot flame that's weak or not touching the tip can cause the same fault, so check the flame first.

Who can fit a thermocouple

Gas work in Australia must be done by a licensed gas fitter, so arrange one to install this thermocouple. They'll turn off the gas supply, swap the thermocouple, position the tip correctly in the pilot flame and leak test the connections. A thermocouple that sits outside the flame will drop out again, so tip position matters as much as the part itself.

Questions about this part

Is 600mm long enough for my appliance?

Measure the old thermocouple along its lead, from the tip to the valve connection. If it's around 600mm or a little shorter, this length should suit, as spare lead can be looped neatly away from the burner. A much longer original needs a longer kit.
