The Goodman B1809913S Integrated Furnace Control Board is the genuine OEM ignition control module for the GMNT070-4B gas furnace and compatible Goodman/Amana units. This board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower, reads the flame sensor and safety limits, and flashes diagnostic error codes. It ships with the matching 9-pin wiring harness for a clean, correct connection. Symptoms of a failed board include no ignition, blower running constantly, no response to the thermostat, or repeated diagnostic lockout codes.

  • Type: Integrated furnace control (IFC) with ignition sequencing
  • Harness: Includes 9-pin plug-in wiring harness
  • Diagnostics: On-board LED fault codes for troubleshooting
  • Controls: Inducer, blower, gas valve, safety circuits
  • Fits: GMNT070-4B and select Goodman/Amana furnaces

OEM vs. Generic: The genuine B1809913S is pre-programmed with the exact ignition timings, blower delays, and safety logic Goodman engineered for this furnace family. Universal aftermarket boards require field configuration of jumpers and timings and can misbehave with the factory harness. Because the control board governs combustion safety, the OEM board with its included harness is the reliable choice.

Installation difficulty: Moderate (⭐⭐⭐☆☆). Photograph existing connections, transfer wiring to the new board, and seat the 9-pin harness. Plan for 45–60 minutes. Cut power at the disconnect first. Professional installation is recommended if you are not comfortable with furnace wiring.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT070-4B — B1809913S?
Yes. This is the factory-specified OEM control board for the Goodman GMNT070-4B — 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 GMNT070-4B — 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.
How fast does National HVAC Parts ship?
