{"product_id":"543-205","title":"543-205","description":"The 3\" High Limit Switch L205-30F is a vital safety component engineered for modern heating systems and residential furnaces. This thermal sensor acts as a fail-safe by monitoring internal temperatures within the heat exchanger. Designed to protect your HVAC equipment from overheating, the switch automatically opens the circuit when the temperature reaches 205°F and resets once it cools down by 30°F. If your furnace blower runs continuously or the burner fails to ignite, a faulty limit control switch may be the cause. This high-quality replacement part ensures your heating unit operates within safe thermal parameters, extending the lifespan of your appliance and maintaining home safety.\u003cbr\u003e\nType: HVAC High Limit Control Switch\u003cbr\u003e\nSize: 3-inch insertion depth\u003cbr\u003e\nDimensions: 3 in\u003cbr\u003e\nApplication: Used in forced-air gas furnaces, air handlers, and various residential heating systems to monitor heat exchanger temperatures and provide thermal protection.\u003cbr\u003e\nSpecifications: Temperature Rating: Opens at 205°F, Closes at 175°F (30°F Differential); Configuration: Normally Closed (NC); Mounting style: Flange-mount for duct or cabinet installation.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ 543-205","offer_id":47251215909149,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ 1416448676","offer_id":47251216007453,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ 38M68","offer_id":47251215941917,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ 38M6801","offer_id":47251215974685,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ 47505","offer_id":47251216105757,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ A1416","offer_id":47251216072989,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L205-30F \/ L205-30F..","offer_id":47251216040221,"sku":null,"price":85.77,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/cf9527c5eb394b28ae02d38d700709d8.webp?v=1773957774","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-205","provider":"BCFurnace","version":"1.0","type":"link"}
