{"product_id":"120-783","title":"120-783","description":"This premium 5-inch insert high limit control switch is a vital safety component for residential and commercial heating systems. Engineered as an L240F-30 thermal limit, this thermostat monitors internal furnace temperatures to prevent hazardous overheating. When the system reaches the critical 240°F threshold, the switch automatically opens to interrupt the heating cycle, protecting the heat exchanger and surrounding components from damage. Once the temperature cools by its 30°F differential, it resets to restore normal operation. Ideal for HVAC maintenance and furnace repair, this durable limit control ensures your heating equipment operates within safe temperature parameters.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 5-inch probe depth\u003cbr\u003e\nDimensions: 5 inches\u003cbr\u003e\nApplication: Gas furnaces, electric heating units, and HVAC air handlers requiring a thermal safety cut-off.\u003cbr\u003e\nSpecifications: Cut-out temperature: 240°F; Differential: 30°F (Resets at 210°F); Configuration: Normally Closed; Mounting: Flange mount with 5-inch probe insert.","brand":"BCFurnace","offers":[{"title":"Limit Switch\/Thermostat, 5\" Insert, L240F-30 \/ 120-783","offer_id":50341992431901,"sku":null,"price":136.29,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch\/Thermostat, 5\" Insert, L240F-30 \/ S1-02532694000","offer_id":50341992464669,"sku":null,"price":136.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d055eebc5ddf4e05873976ae4b216b63.webp?v=1773966270","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-783","provider":"BCFurnace","version":"1.0","type":"link"}
