The Goodman B1809913S Integrated Furnace Control Board is the genuine OEM "brain" of the GMNT070-3B gas furnace, supplied complete with its 9-pin wiring harness. This circuit board manages the entire heating sequence — inducer startup, igniter warm-up, gas-valve timing, flame sensing, blower on/off delays, and safety-limit monitoring — and reports fault codes through its onboard diagnostic LED.

Specifications

Type: Integrated furnace control (IFC) circuit board
Includes: 9-pin wiring harness
Functions: Ignition sequencing, flame sensing, blower timing, diagnostics
Diagnostics: Onboard LED fault-code display
OEM part number: B1809913S
Primary fit: Goodman GMNT070-3B furnace

OEM vs. Generic

Control boards are firmware-specific, so a genuine Goodman OEM board is strongly recommended. It ships with the matching 9-pin harness and factory-programmed timings that align exactly with your furnace's gas valve, igniter, and blower. Universal or aftermarket boards can require rewiring and may not replicate Goodman's ignition and delay sequences, risking short-cycling or lockouts.

Install Difficulty

Moderate (3/5). Kill power at the furnace disconnect and label every wire (or photograph the board) before disconnecting. Transfer connections one at a time to the new board, seat the 9-pin harness fully, and confirm the DIP-switch / jumper settings match the original. Plan on 30–45 minutes. If you're unsure about the wiring, have a licensed HVAC technician perform the swap.

Genuine Goodman reliability, complete with harness and backed by our warranty. Confirm your model number before ordering.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT070-3B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMNT070-3B — 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 GMNT070-3B — 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.
