It interprets the flame sensor, pressure switch, and limit inputs, then fires the igniter and stages the blower with the correct timing. When this board fails you'll see a completely dead furnace, flashing diagnostic LEDs, or a blower that runs nonstop. This genuine Carrier board ships with the correct firmware and matches the GB1AAV060155AGJA harness so every connector and terminal lines up exactly. Installation is moderate — power down, photograph the existing wiring, move the labeled plugs over one at a time, and remount on the factory standoffs in about 30 minutes. The OEM board avoids the timing and miswiring faults that plague generic substitutes. Replacing it restores full, safe, code-compliant operation and clears persistent lockouts. Order before 3PM CST for same-day shipping from our in-stock inventory and minimize downtime. Genuine OEM quality gives you dependable, safe heating control you can rely on.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV060155AGJA.\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":62942747361651,"sku":"carrier-control-board-gb1aav060155agja","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-gb1aav060155agja.jpg?v=1781467728","url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-gb1aav060155agja","provider":"National HVAC Parts","version":"1.0","type":"link"}
