The Goodman B1809913S Integrated Furnace Control Board is the genuine OEM brain of your GMNT100-4B gas furnace, supplied complete with the 9-pin wiring harness for a direct replacement. This board sequences the entire heating cycle — inducer startup, ignition, gas valve timing, flame sensing, and blower on/off delays — while continuously monitoring the limit, rollout, and pressure safety switches. It is compatible with the GMNT100-4B and select Goodman/Amana furnaces using the same control platform.

Specifications

Function: Integrated furnace control (ignition + blower + safety logic)
Includes: 9-pin plug-in wiring harness
Onboard diagnostics: LED fault-code output
OEM Part Number: B1809913S
Compatibility: GMNT100-4B and select Goodman/Amana furnaces
Type: Direct-replacement factory board

OEM vs. Generic

The genuine OEM B1809913S is flashed with Goodman's exact ignition sequence and safety timings and includes the correct 9-pin harness for a true plug-and-play swap. Aftermarket or 'universal' boards can require rewiring, may not honor the original blower delays, and often void diagnostic LED functionality. For a control this central to safe operation, OEM is the reliable choice.

Symptoms of a Failed Control Board

No ignition, no inducer, or no blower response
Furnace locks out with erratic or no LED flash codes
Burners fire but blower never engages (or runs constantly)

Installation Difficulty: Moderate

Cut power at the disconnect, photograph the existing wiring, and transfer connectors one at a time to the identical terminals — the included 9-pin harness makes the main plug foolproof. Allow 30–45 minutes. If you are unsure about wiring or the furnace still won't cycle, we recommend a licensed HVAC technician to verify flame sensing and gas-valve timing.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT100-4B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMNT100-4B — 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 GMNT100-4B — 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.
