When a furnace won't ignite, short-cycles, runs its blower continuously, or flashes error codes, a defective control board is a common cause. Installing the exact factory replacement restores correct communication between the thermostat, gas valve, hot-surface igniter, pressure switch, and limit circuits. This is an intermediate repair for confident DIYers and technicians; allow 30 to 60 minutes and transfer each connector one at a time to prevent miswiring. Always shut off power at the breaker first and confirm the board's pin layout matches your original. OEM guarantees correct firmware, ignition timing, and connector fit for the GA2AAD036070ABJA, protecting both performance and warranty. In stock and ready to go. Order before 3PM CST for same-day shipping so you can restore heat quickly. Trusted by HVAC professionals for factory-correct Carrier boards and backed by our fit guarantee.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GA2AAD036070ABJA.\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":62942845010291,"sku":"carrier-control-board-ga2aad036070abja","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-ga2aad036070abja.jpg?v=1781467719","url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-ga2aad036070abja","provider":"National HVAC Parts","version":"1.0","type":"link"}
