Limit switches are critical safety components in any furnace. They monitor the temperature inside the heat exchanger or plenum. When the temperature rises above a set threshold, the switch opens and shuts off the burner. This protects the heat exchanger from overheating and prevents damage to the system. Once temperatures return to a safe level, an auto-reset limit switch closes again automatically, restoring normal operation without requiring a manual reset by a technician. The SOURCE1 2533325000 features an open temperature of 195 degrees Fahrenheit and a close temperature of 165 degrees Fahrenheit. This 30-degree differential is a standard range found in many residential and light commercial gas furnace applications. HVAC technicians will recognize this as a common specification for high-limit controls used in upflow, downflow, and horizontal furnace configurations. The auto-reset function means the switch will cycle back to the closed position on its own once the system cools down. This makes it suitable for applications where nuisance lockouts need to be minimized while still providing reliable overheat protection. Replacing a faulty limit switch is one of the most common furnace service calls. A failed limit switch can cause a furnace to short-cycle, run continuously on the blower, or fail to ignite. Using a direct replacement like the SOURCE1 2533325000 ensures proper temperature calibration and reliable performance. This part is compatible with a wide range of gas furnace brands and models that use a standard limit switch with these open and close ratings. HVAC service professionals and wholesale parts suppliers stock this type of component for routine maintenance and emergency repair work.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAuto-reset design restores normal furnace operation automatically after the heat exchanger cools to the close temperature\u003c\/li\u003e\n\u003cli\u003eOpen temperature of 195 degrees Fahrenheit and close temperature of 165 degrees Fahrenheit for precise overheat protection\u003c\/li\u003e\n\u003cli\u003eStandard limit switch form factor fits a wide range of residential and light commercial gas furnace applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe SOURCE1 2533325000 limit switch provides dependable high-temperature safety control in gas furnace systems, with a 195 degree open and 165 degree close rating and a convenient auto-reset function that eliminates the need for manual intervention after a thermal trip event.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOURCE1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2533325000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Limit Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature\u003c\/strong\u003e: 195 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClose Temperature\u003c\/strong\u003e: 165 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Auto Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Gas Furnace Overheat Protection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51121032692018,"sku":"2533325000","price":92.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304884719.jpg?v=1778043701","url":"https:\/\/voomisupply.com\/products\/source1-2533325000-limit-switch-195-165-open-close-auto-reset","provider":"Voomi Supply","version":"1.0","type":"link"}
