{"product_id":"000-227","title":"000-227","description":"Ensure the safety and efficiency of your HVAC system with this high-quality Lennox Limit Switch. Designed as a high-limit thermal control, this L140-30F fan disc switch acts as a critical safety mechanism by monitoring the internal temperature of your furnace or heating unit. If the system exceeds a safe operating temperature of 140°F, the switch opens to interrupt the circuit, preventing potential damage or hazards caused by overheating. Once the unit cools by a 30°F differential, the switch resets to restore normal operation. This reliable white-label replacement part is essential for resolving issues like furnace short-cycling or thermal cutout failures, providing peace of mind and maintaining consistent climate control in residential or commercial settings.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Commonly used in residential and commercial heating units, gas furnaces, and rooftop HVAC systems as a primary or secondary safety limit control.\u003cbr\u003e\nSpecifications: Cut-out temperature: 140°F; Differential: 30°F; Cut-in temperature: 110°F; Logic: Opens on temperature rise (Normally Closed).","brand":"BCFurnace","offers":[{"title":"LENNOX LIMIT SWITCH\/THERMOSTAT, WHITE LABEL, L140-30F \/ 000-227","offer_id":50215780450589,"sku":null,"price":51.99,"currency_code":"CAD","in_stock":true},{"title":"LENNOX LIMIT SWITCH\/THERMOSTAT, WHITE LABEL, L140-30F \/ 97J67","offer_id":50215780483357,"sku":null,"price":51.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/559f7bbeb37f4170ab7a000d842dab04.webp?v=1773960634","url":"https:\/\/bcfurnace.myshopify.com\/products\/000-227","provider":"BCFurnace","version":"1.0","type":"link"}
