This auto-reset switch monitors supply air or heat exchanger temperatures and interrupts the burner circuit when temperatures exceed the set limit range of 185 to 215 degrees F, then automatically resets once conditions return to normal. The switch features a 3 inch insert length and is identified by its pink and white color coding. It is installed by licensed HVAC technicians as part of routine furnace service or component replacement.\u003c\/p\u003e\u003cp\u003eThis limit control switch is intended for use in residential and light commercial gas furnaces where overtemperature protection is required. The auto-reset function makes it suitable for applications where nuisance lockouts from brief temperature spikes must be minimized. It is a direct-replacement style component used during furnace tune-ups, heat exchanger service, or limit switch failure diagnostics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAuto-reset operation returns the switch to normal function once temperatures drop below the limit threshold\u003c\/li\u003e\n\u003cli\u003eOperating range of 185 to 215 degrees F suits a wide variety of residential furnace applications\u003c\/li\u003e\n\u003cli\u003e3 inch insert length for proper depth placement in the furnace plenum or heat exchanger compartment\u003c\/li\u003e\n\u003cli\u003ePink and white color coding aids identification and replacement verification in the field\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement limit control switch for residential and light commercial gas furnaces requiring a 3 inch insert, auto-reset style limit with a 185 to 215 degrees F operating range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLimit control switches are installed by qualified HVAC technicians.
