OEM Carrier Furnace Control Board for Model GB3AAV036050AFJA

This genuine OEM Carrier integrated furnace control board is the brain of your GB3AAV036050AFJA gas furnace. It manages the entire ignition sequence—monitoring the pressure switch, energizing the igniter and gas valve, verifying the flame sensor signal, and controlling blower timing and safety lockouts. When a control board fails, symptoms range from a completely dead furnace and no response to the thermostat, to erratic blower operation, repeated lockouts, or fault LED error codes. This board is programmed and pinned for the GB3AAV036050AFJA, so the connector layout and ignition logic match the original exactly. Installation takes about 30-45 minutes and is best for an experienced DIYer or technician: photograph the wiring first, transfer harnesses one at a time to the new board, and confirm the dip-switch settings match. Always shut off power and gas before servicing. Restore full, reliable furnace operation with a true OEM replacement rather than a risky aftermarket board. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB3AAV036050AFJA?
Yes. This is the factory-specified OEM control board for the Carrier Model GB3AAV036050AFJA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier Model GB3AAV036050AFJA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
