It senses the negative pressure produced by the inducer motor and blocks ignition when a clogged flue, weak inducer, or blocked condensate line is present. A failed pressure switch commonly triggers ignition lockouts, no-heat calls, or repeated safety cycling. Made to exact Carrier specifications, this genuine replacement provides the correct trip pressure and port setup for safe, code-compliant operation. It is a direct-fit replacement for the GB3AAV024070ACJA, no modification needed. Installation is relatively easy for a handy homeowner or HVAC tech: disconnect power, pull the hose and spade connectors, and install the new switch. Confirm the breaker is off before you begin. OEM guarantees the precise pressure rating your furnace requires for safe combustion, unlike generic alternatives. In stock and ships same-day on orders before 3PM CST. Restore safe, reliable heat with genuine Carrier parts you can count on.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB3AAV024070ACJA.\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":62942739530099,"sku":"carrier-pressure-switch-gb3aav024070acja","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-gb3aav024070acja.jpg?v=1781470606","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-gb3aav024070acja","provider":"National HVAC Parts","version":"1.0","type":"link"}
