Bifilar means the lead carries two separate wires instead of the usual single core and outer sheath, so it isn't interchangeable with a standard thermocouple. Check your old thermocouple for the 0290023 number, a twin wire lead and the 510mm length before you order.\u003c\/p\u003e\n\u003ch2\u003eWhen to replace a Blanco bifilar thermocouple\u003c\/h2\u003e\n\u003cp\u003eLike any thermocouple, this probe heats in the burner flame and produces a small voltage that holds the gas safety valve open. If the flame goes out, the voltage collapses and the valve closes. After years in the flame the tip deteriorates and its output drops. The usual sign is a burner that won't stay alight once the knob is released, or one that goes out by itself on low. Damaged insulation on the twin wires can also cause intermittent dropouts, so inspect the full length of the lead.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Blanco part 0290023\u003c\/li\u003e\n\u003cli\u003eBifilar (twin wire) thermocouple\u003c\/li\u003e\n\u003cli\u003e510mm length\u003c\/li\u003e\n\u003cli\u003eGas safety part for licensed gas fitter installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e510mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eBifilar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eFitting a bifilar thermocouple\u003c\/h2\u003e\n\u003cp\u003eBook a licensed gas fitter, as Australian rules require gas work to be done by one. Isolate the gas and switch the appliance off at the wall first. Take note of how both conductors of the old lead connect, as a bifilar lead terminates differently from a standard one. Mount the tip in the same position at the burner, route the lead away from heat and test the burner shuts off correctly.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eCan I use a standard thermocouple instead?\u003c\/h3\u003e\u003cp\u003eNo. This is a bifilar thermocouple, with a different lead and connection from a standard single core type. Replace it with the same type and length. If your old thermocouple is marked 0290023 or measures 510mm with a twin wire lead, this is the match.\u003c\/p\u003e","brand":"Blanco","offers":[{"title":"Default Title","offer_id":44551223181390,"sku":"0290023","price":19.34,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/partsshop.com.au\/products\/0290023-genuine-blanco-bifilar-gas-thermocouple-510mm","provider":"My Store","version":"1.0","type":"link"}
