It senses negative pressure created by the inducer motor and proves the flue is clear, protecting against dangerous flue-gas spillage. A stuck or failed switch commonly causes the furnace to lock out with the inducer running but no ignition, often flagged by a pressure-switch error code. Manufactured to exact factory specifications, this switch matches the original trip point, port configuration, and electrical terminals for a direct fit on the Carrier GB3AAV024050AEJA gas furnace. Installation is easy and DIY-friendly: shut off power, disconnect the rubber hose and two spade terminals, remove the mounting screws, and install the replacement in minutes. Be sure the hose is free of condensate or blockage, a frequent cause of nuisance trips. Every switch is tested to its rated set point before shipping. In stock and ready to ship same-day when you order before 3 PM CST, getting your heat restored quickly.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB3AAV024050AEJA.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62942743134579,"sku":"carrier-pressure-switch-gb3aav024050aeja","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-gb3aav024050aeja.jpg?v=1781469595","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-gb3aav024050aeja","provider":"National HVAC Parts","version":"1.0","type":"link"}
