The switch opens at 195 degrees F and closes at 165 degrees F, interrupting the burner circuit when the supply-air temperature exceeds the setpoint and automatically restoring operation once temperatures drop back to the close threshold. Licensed HVAC technicians install this component as a direct OEM replacement during routine service or after a no-heat diagnostic points to a failed or out-of-spec limit device.\u003c\/p\u003e\u003cp\u003eThis limit switch is suited for residential gas furnaces where automatic-reset high-limit protection is required. It mounts in the supply-air plenum or heat exchanger compartment, where it monitors discharge air or heat exchanger temperature. The auto-reset design eliminates the need for a manual reset after a nuisance trip, provided the root cause of the overtemperature event has been corrected before returning the unit to service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpens at 195 degrees F to interrupt the burner circuit on overtemperature\u003c\/li\u003e\n\u003cli\u003eCloses at 165 degrees F for automatic circuit restoration\u003c\/li\u003e\n\u003cli\u003eAuto-reset operation — no manual reset required after the temperature normalizes\u003c\/li\u003e\n\u003cli\u003eOEM YORK part, built to match original furnace specifications\u003c\/li\u003e\n\u003cli\u003eDirect replacement for failed or out-of-spec high-limit switches in applicable YORK equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement high-limit switch for YORK residential gas furnace and air handler systems where a 195 degrees F open \/ 165 degrees F close auto-reset limit device is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed HVAC technician should perform this replacement. Shut off all power to the furnace at the disconnect and set the thermostat to the off position before beginning work. After installing the new limit switch, verify that airflow restrictions, dirty filters, or blocked registers are corrected to prevent repeat tripping. Refer to applicable local mechanical codes and the unit service manual for mounting orientation and wiring termination requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature\u003c\/strong\u003e: 195 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClose Temperature\u003c\/strong\u003e: 165 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Automatic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YORK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: s1-02533325000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51200307429682,"sku":"S1-02533325000","price":116.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307152463.jpg?v=1779688865","url":"https:\/\/voomisupply.com\/products\/york-s1-02533325000-limit-switch-auto-reset-195-165f","provider":"Voomi Supply","version":"1.0","type":"link"}
