{"product_id":"020-780","title":"020-780","description":"This L145-30F high limit control switch is a vital safety component for residential gas furnaces and HVAC heating systems. Designed as a disc-style thermostat, this part monitors the internal temperature of the heat exchanger to prevent overheating. If the temperature reaches the safety threshold of 145°F, the switch opens to interrupt the heating cycle, protecting your appliance from potential damage. It features an automatic reset with a 30°F differential, meaning it will close again once the temperature drops to 115°F. This replacement part is ideal for fixing issues where a furnace is short-cycling or failing to stay on due to a faulty safety sensor.\u003cbr\u003e\nType: High Limit Control Switch \/ Thermostat\u003cbr\u003e\nSize: Standard furnace disc size\u003cbr\u003e\nApplication: Used primarily in gas furnaces, electric heaters, and HVAC air handlers to provide over-temperature protection and fan motor control.\u003cbr\u003e\nSpecifications: Cut-out temperature: 145°F; Differential: 30°F; Switch logic: Normally Closed (NC), opens on temperature rise; Reset type: Automatic.","brand":"BCFurnace","offers":[{"title":"Limit Switch\/Thermostat, L145-30F \/ 020-780","offer_id":50216184938781,"sku":null,"price":54.56,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch\/Thermostat, L145-30F \/ SWT03940","offer_id":50216184971549,"sku":null,"price":54.56,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/e833e22c797a410d95ea44565a2a7e88.webp?v=1773962575","url":"https:\/\/bcfurnace.myshopify.com\/products\/020-780","provider":"BCFurnace","version":"1.0","type":"link"}
