It's the set of small switches, wired together in a chain, that sit behind the control knobs and trigger the ignition spark when a knob is pushed in and turned. No models are on file, so compare the number of switches and the connector with the old chain before ordering.\u003c\/p\u003e\n\u003ch2\u003eBlanco cooktop igniter not sparking or clicking non-stop?\u003c\/h2\u003e\n\u003cp\u003eEach burner valve has a microswitch fitted to it, and all the switches connect along one harness to the spark generator. Pressing a knob closes its switch and the generator fires the electrodes. If a switch sticks closed, often after a boil-over gets moisture or food into it, the igniters click constantly even with every knob off. A switch that won't close leaves one or all burners without a spark. Drying out the cooktop sometimes stops the clicking, but a corroded or cracked switch needs replacing.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Blanco part 50070\u003c\/li\u003e\n\u003cli\u003eAlso listed as 0050070 and 050070\u003c\/li\u003e\n\u003cli\u003eIgnition microswitches linked in a daisy chain harness\u003c\/li\u003e\n\u003cli\u003eFor Blanco gas cooktops\u003c\/li\u003e\n\u003cli\u003eCheck the switch count and plug against the old chain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eMicroswitch daisy chain\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eWho should fit the microswitch chain\u003c\/h2\u003e\n\u003cp\u003eThis part goes inside a gas appliance, so have a licensed gas fitter do the work. Switch the cooktop off at the wall and turn off the gas before the knobs and top are removed. Each switch clips onto its valve, and the harness plugs into the ignition module. Route the wiring clear of hot surfaces and test that each burner sparks only while its knob is pressed.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eMy igniters keep clicking after cleaning. Is it this part?\u003c\/h3\u003e\u003cp\u003eVery often, yes. Water or cleaning spray can get into a switch and hold it closed. Let the cooktop dry out fully for a day or two first. If the clicking carries on, one of the switches has failed and the chain should be replaced.\u003c\/p\u003e","brand":"Blanco","offers":[{"title":"Default Title","offer_id":44551367721038,"sku":"50070","price":80.06,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/50070-genuine-blanco-gas-cooktop-ignition-microswitch-daisy-chain.jpg?v=1792026465","url":"https:\/\/partsshop.com.au\/products\/50070-genuine-blanco-gas-cooktop-ignition-microswitch-daisy-chain","provider":"My Store","version":"1.0","type":"link"}
