Switches like this sit behind the control knob on an electric cooktop and set the power level for a cooking zone. If one hotplate won't heat, only works on certain settings or won't turn off, the switch is a common culprit. Check the number on the side of your old switch before ordering.\u003c\/p\u003e\n\u003ch2\u003eSigns a Blanco cooktop control switch has failed\u003c\/h2\u003e\n\u003cp\u003eEach step on the switch changes how power is fed to the element, giving more or less heat as you turn the knob. Over time the contacts burn and pit, especially on the high settings, and the terminals can overheat where they connect to the wiring. Common symptoms are a cooking zone that stays cold, heats on high only, runs flat out on every setting or won't switch off. Melted or discoloured terminals, a burning smell under the cooktop or a knob that no longer clicks firmly between steps also point to the switch.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Blanco part H3530200040\u003c\/li\u003e\n\u003cli\u003eEGO rotary step switch\u003c\/li\u003e\n\u003cli\u003eOff plus 9 heat steps\u003c\/li\u003e\n\u003cli\u003eFor Blanco electric cooktops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePositions\u003c\/th\u003e\n\u003ctd\u003eOff plus 9 steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003ctd\u003eEGO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eReplacing the rotary switch\u003c\/h2\u003e\n\u003cp\u003eElectric cooktops are hard-wired, so isolate the circuit at the switchboard and have a licensed electrician carry out the replacement. Before disconnecting the old switch, photograph or label every terminal, as step switches carry several wires and the order matters. Transfer each wire to the same terminal on the new switch, refit the knob and check every step from 1 to 9 heats correctly.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eCan I use any 9 step switch?\u003c\/h3\u003e\u003cp\u003eStick with the same part. Step switches with the same number of positions can have different internal wiring and terminal layouts. If your old switch shows H3530200040, this is the direct replacement for your Blanco cooktop.\u003c\/p\u003e","brand":"Blanco","offers":[{"title":"Default Title","offer_id":44551223443534,"sku":"H3530200040","price":148.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/h3530200040-genuine-blanco-cooktop-rotary-switch-0-9-step.jpg?v=1792026598","url":"https:\/\/partsshop.com.au\/products\/h3530200040-genuine-blanco-cooktop-rotary-switch-0-9-step","provider":"My Store","version":"1.0","type":"link"}
