Goodman B1809913S Integrated Furnace Control Board

The B1809913S is a genuine Goodman integrated furnace control board, shipped with the matching 9-pin wiring harness for a clean, direct-fit replacement on the GMT045-3B and compatible Goodman/Amana gas furnaces. This board is the brain of the furnace: it manages the ignition sequence, blower and inducer timing, safety-circuit monitoring, and diagnostic fault codes. A failed board typically shows up as a no-heat condition, blinking LED error codes, or a furnace that will not initiate ignition.

Specifications

Function: Integrated ignition / blower control board
Includes: 9-pin wiring harness
Onboard diagnostics: LED fault-code indication
Fit: Direct OEM replacement for GMT045-3B
Brand: Goodman genuine OEM part

OEM vs. Generic

The genuine Goodman OEM board is programmed with the exact ignition and timing logic this furnace requires, and the included harness eliminates wiring adaptation. Aftermarket or re-flashed boards can introduce timing mismatches, erratic blower behavior, or premature failure. For the furnace's core control, OEM protects the whole system.

Installation Difficulty

Moderate (3 of 5). Photograph every connection, transfer wires one at a time, and seat the 9-pin harness fully. Cut power at the disconnect first. Because this is a line-voltage combustion control, professional installation by a licensed HVAC technician is recommended.

Frequently Asked Questions

Does this Control Board fit my Goodman GMT045-3B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMT045-3B — B1809913S. 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 Goodman GMT045-3B — B1809913S?

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 Goodman 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 Goodman 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.
