{"product_id":"120-823","title":"120-823","description":"This high-performance 140-degree automatic reset limit switch is a critical safety component designed for HVAC systems and furnace units. Functioning as a high-limit control, it monitors internal temperatures to protect your heating equipment from overheating. When the system reaches the 140°F threshold, the switch automatically opens to disrupt the heating circuit, preventing potential damage or safety hazards. As the unit cools back down to a safe operating temperature, the switch automatically resets to restore system functionality. This fan disc limit switch is a reliable replacement part for ensuring consistent airflow and thermal protection in residential and commercial climate control systems.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Commonly used in furnaces, air handlers, and packaged heating and cooling units to monitor plenum temperature and prevent overheating.\u003cbr\u003e\nSpecifications: Temperature Trip Point: 140°F; Reset Type: Automatic; Contact Configuration: Normally Closed (Opens on temperature rise)","brand":"BCFurnace","offers":[{"title":"SWITCH,LIMIT 140,AUTO \/ 120-823","offer_id":50216974057757,"sku":null,"price":37.63,"currency_code":"CAD","in_stock":true},{"title":"SWITCH,LIMIT 140,AUTO \/ S1-02546403000","offer_id":50216974090525,"sku":null,"price":37.63,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/120-823","provider":"BCFurnace","version":"1.0","type":"link"}
