The genuine Goodman B1809913S Integrated Furnace Control Board is the brain of your GMNT090-5B gas furnace, managing the complete ignition sequence, blower timing, safety lockouts, and diagnostic fault codes.

Specifications

OEM Part Number: B1809913S
Type: Integrated ignition & blower control board
Includes: 9-pin main wiring harness
Fits: Goodman GMNT090-5B gas furnace
Functions: Ignition sequencing, blower on/off delays, safety monitoring, LED diagnostic codes
Brand: Goodman (genuine OEM)

OEM vs. Generic

Aftermarket "universal" boards require field jumper configuration and rarely reproduce the exact blower timing profiles and fault logic of the original. Mismatched firmware can cause short cycling, poor comfort, and confusing diagnostics. The OEM B1809913S is factory-flashed for the GMNT090-5B and includes the correct harness, eliminating guesswork and warranty risk.

Installation Difficulty

Moderate (3/5). Photograph all wire connections first, cut furnace power, then transfer connectors one at a time from the old board to the new one to avoid errors. The 9-pin harness keys in a single orientation. Budget 30–45 minutes. Line-voltage and gas-appliance work is involved — if you are unsure, hire a licensed HVAC technician.

Disconnect all electrical power before servicing to prevent shock or board damage.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT090-5B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMNT090-5B — 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 GMNT090-5B — 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.
