The Goodman B1809913S Integrated Furnace Control (IFC) Board is a genuine OEM replacement engineered for the GMNT080-4B gas furnace.

Specifications

Part Number: B1809913S
Compatible Model: GMNT080-4B (80,000 BTU furnace)
Harness: 9-pin quick-connect included
Function: Ignition control, blower timing, safety monitoring, LED diagnostics
Brand: Goodman (OEM)

OEM vs. Generic

Unlike universal aftermarket boards that require reprogramming jumper settings and manual timing configuration, this OEM B1809913S is pre-matched to the GMNT080-4B ignition and blower profile. That means correct heat-rise, verified safety-circuit logic, and no guesswork. Generic boards may save a few dollars but risk short-cycling, nuisance lockouts, and voided equipment warranties.

Installation Difficulty: Moderate

Rated 3/5. Replacement involves shutting off power and gas, photographing the existing wiring, transferring the harness plugs, and mounting the board on the standoffs. Most experienced DIYers complete it in 30–45 minutes; if you are unsure about wiring or fault-code interpretation, we recommend a licensed HVAC technician. Always confirm power is disconnected at the breaker before servicing.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT080-4B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMNT080-4B — 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 GMNT080-4B — 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.
