Thermal Switch","description":"\u003cp\u003ePart 85805410012702 is a genuine Electrolux thermal cut-out rated at 50 degrees, with normally open contacts. It comes from the Electrolux group cooking range and responds at a far lower temperature than a typical oven safety cut-out, so it suits circuits that need to react as soon as things start to warm. Make sure the rating and contact type stamped on your old switch match before ordering.\u003c\/p\u003e\n\u003ch2\u003eSigns a low temperature thermal switch has failed\u003c\/h2\u003e\n\u003cp\u003eMost thermal switches of this kind use a bimetal disc that flips when its mounting surface reaches the set point, here 50 degrees, changing the state of the contacts. Over many cycles the disc can weaken and the contacts can pit, so the switch may stop responding, react at the wrong temperature, or chatter on and off. The symptom depends on what it controls. A fan or indicator might never come on, or might run constantly. A multimeter check across the terminals, cool and then warm, shows whether it still switches.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Electrolux part 85805410012702\u003c\/li\u003e\n\u003cli\u003eThermal cut-out rated 50 degrees\u003c\/li\u003e\n\u003cli\u003eNormally open (N.O.) contacts\u003c\/li\u003e\n\u003cli\u003eFrom the Electrolux group cooking range, no models on file\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature\u003c\/th\u003e\n\u003ctd\u003e50 degrees C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eContacts\u003c\/th\u003e\n\u003ctd\u003eNormally open (N.O.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eReplacing the 50 degree switch\u003c\/h2\u003e\n\u003cp\u003eTurn power off at the switchboard before opening any panel, and have a licensed electrician handle hard-wired appliances. Photograph the leads, remove the old switch from its bracket and clean the mounting face so the new one makes full contact.
