It is the flame failure sensor that keeps the gas valve open while the burner is alight. Several similar looking lengths and types exist, so match the 600mm length, the 106 reference and the fitting at the valve end. No models are on file, so send your model number through the parts enquiry form for a check.\u003c\/p\u003e\n\u003ch2\u003eBurner won't stay lit after releasing the knob\u003c\/h2\u003e\n\u003cp\u003eA thermocouple sits in the flame and generates a tiny voltage when heated. That voltage holds a magnet in the gas valve open. If the flame goes out, the thermocouple cools and the valve shuts, stopping unburnt gas escaping. When a thermocouple weakens, the burner lights but goes out as soon as you let go of the knob, or after a few seconds. A tip that's dirty or bent out of the flame can do the same, so check its position before replacing it.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Fisher \u0026amp; Paykel part 577618\u003c\/li\u003e\n\u003cli\u003eCoaxial thermocouple\u003c\/li\u003e\n\u003cli\u003e600mm length\u003c\/li\u003e\n\u003cli\u003eType 106\u003c\/li\u003e\n\u003cli\u003eGas safety part, licensed gas fitter to fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eCoaxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e600mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReference\u003c\/th\u003e\n\u003ctd\u003e106\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eFitting a thermocouple\u003c\/h2\u003e\n\u003cp\u003eTurn off the gas supply and isolate the power first. In Australia, thermocouple replacement on a gas appliance is a job for a licensed gas fitter. Route the new lead the same way as the old one, without sharp bends or contact with hot burner parts, and tighten the valve connection firmly but not hard. Check the burner stays lit and that the flame failure works.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eCan I use a shorter thermocouple?\u003c\/h3\u003e\u003cp\u003eNo. The lead must reach from the burner to the valve along the original route. A different length or type may not fit the burner bracket or the valve, so match the 600mm length and type 106.\u003c\/p\u003e","brand":"Fisher \u0026 Paykel","offers":[{"title":"Default Title","offer_id":44551419560014,"sku":"577618","price":21.48,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/partsshop.com.au\/products\/577618-genuine-fisher-and-paykel-coaxial-thermocouple-600mm-type-106","provider":"My Store","version":"1.0","type":"link"}
