{"product_id":"040-687","title":"040-687","description":"The L165-20F High Limit Switch is a critical safety component designed for furnace and residential heating systems. As a snap-action fan disc control, this thermal switch monitors the internal temperature of your HVAC unit to prevent overheating. If the temperature exceeds the safe operating threshold of 165°F, the switch interrupts power to the heating element or gas valve, protecting your equipment from damage and ensuring home safety. This replacement part is ideal for repairing furnaces where the blower runs constantly or the system cycles off too quickly. Engineered for reliability, this high-limit sensor automatically resets once the temperature drops, restoring normal operation to your heating system.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: Standard snap-disc size\u003cbr\u003e\nDimensions: not specified × not specified × not specified\u003cbr\u003e\nApplication: Gas furnaces, electric heaters, blowers, and HVAC forced-air systems requiring high-temperature safety monitoring.\u003cbr\u003e\nSpecifications: Temperature Open: 165°F; Temperature Close: 145°F (20°F differential); Switch Type: Normally Closed; Reset Type: Automatic.","brand":"BCFurnace","offers":[{"title":"L165-20F LIMIT SWITCH \/ 040-687","offer_id":50216000880925,"sku":null,"price":31.6,"currency_code":"CAD","in_stock":true},{"title":"L165-20F LIMIT SWITCH \/ 338096-703","offer_id":50216000913693,"sku":null,"price":31.6,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/040-687","provider":"BCFurnace","version":"1.0","type":"link"}
