OEM Carrier Control Board for Model GB3AAV036050AGJA Furnace

This OEM Carrier furnace control board is the factory-matched integrated board that runs the complete heating sequence on the GB3AAV036050AGJA gas furnace. It governs ignition timing, inducer and blower operation, safety interlocks, and flame sensing, and it flashes diagnostic fault codes to speed troubleshooting. When the board fails, symptoms include a completely dead furnace, no blower, intermittent heat, or erratic short-cycling. Selecting the genuine Carrier board guarantees the correct firmware, relay ratings, and connector layout so your existing wiring harness plugs straight in. Installation is moderate: kill power at the disconnect, photograph the wiring for reference, move connectors one at a time to the new board, and mount it in the original location. Most installs run 30–45 minutes, and using the OEM board avoids the cross-reference and compatibility issues common with aftermarket units. Genuine parts protect your warranty and keep full diagnostics intact. In stock and ready to ship—orders before 3PM CST go out same-day. Restore code-correct, reliable operation to your Carrier GB3AAV036050AGJA with the correct factory control board.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB3AAV036050AGJA Furnace?
Yes. This is the factory-specified OEM control board for the Carrier Model GB3AAV036050AGJA Furnace. 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 GB3AAV036050AGJA Furnace?
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?
