It monitors draft inducer airflow and venting pressure, closing only when proper combustion airflow is confirmed and locking out ignition if a blocked vent, failing inducer motor, or condensate restriction is detected. Installing the correct factory-spec switch restores reliable ignition sequencing and prevents nuisance lockouts and short cycling. Because it is the genuine Carrier component, the pressure setpoint, port configuration, and tube connections match your furnace exactly—no guesswork or universal adapters. This is a moderate DIY repair for handy homeowners: shut off power and gas, photograph the wiring, transfer the hose and spade terminals, and mount the new switch in roughly 20 to 30 minutes. HVAC technicians can complete it even faster. Pairs perfectly with a fresh hose and grommet if yours show cracking. All in-stock OEM Carrier parts ship same-day when your order is placed before 3PM CST, so you can get heat back fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GA1AAD066105ACJA.\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":62942847172979,"sku":"carrier-pressure-switch-ga1aad066105acja","price":54.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-ga1aad066105acja.jpg?v=1781469724","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-ga1aad066105acja","provider":"National HVAC Parts","version":"1.0","type":"link"}
