When the board fails you may see no response at all, a blower that won't shut off, erratic cycling, or a flashing error LED. This board is the correct direct-fit replacement for the Carrier GB1AAV036045AGJA gas furnace, with matching relay layout, connector pinouts, and firmware so your existing wiring harness plugs right in. Replacement is moderate in difficulty—best for confident DIYers or a technician: photograph the wiring, cut power, transfer connectors one at a time to the identical terminals, and remount. Installing the OEM board preserves Carrier's exact timing and safety logic that generic boards often approximate incorrectly, which can cause nuisance faults. Each board is tested to OEM specification. In stock and ships same-day when you order before 3PM CST. Restore full furnace control and clear those fault codes with the board Carrier built for your unit.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV036045AGJA.\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":62942820991347,"sku":"carrier-control-board-gb1aav036045agja","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-gb1aav036045agja.jpg?v=1781469446","url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-gb1aav036045agja","provider":"National HVAC Parts","version":"1.0","type":"link"}
