When this board fails, the furnace may fail to ignite, short-cycle, throw error codes, or stop responding to the thermostat entirely. Replacing a faulty board restores reliable, safe automatic operation. This factory-spec integrated furnace control is matched to the GA2AAD036055ABJA's sequencing and sensor inputs, so you get plug-in compatibility and proper diagnostics. Installation is moderate difficulty—plan 30 to 45 minutes. Label and transfer the wiring harnesses one at a time, set any DIP switches to match the original, and confirm the flame-sense and limit connections. Always shut off power and gas before servicing. Genuine OEM ensures correct firmware and timing that generic boards can't guarantee. In stock and ships same-day when ordered before 3PM CST. Order now to bring heat back to your home quickly with a trusted factory replacement.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GA2AAD036055ABJA.\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":62942845436275,"sku":"carrier-control-board-ga2aad036055abja","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-ga2aad036055abja.jpg?v=1781467715","url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-ga2aad036055abja","provider":"National HVAC Parts","version":"1.0","type":"link"}
