Goodman B1809913S Integrated Furnace Control Board (9-Pin Harness)

The B1809913S is the genuine OEM integrated furnace control (IFC) board for the Goodman/Amana GMNT090-4B gas furnace, supplied with the 9-pin wiring harness for a complete replacement. This board is the furnace's brain: it manages the ignition sequence, inducer and blower timing, safety-circuit monitoring (limits, rollout, pressure switch), and thermostat calls. Symptoms of a failed board include no ignition, blower running constantly, LED fault codes, or a dead furnace.

Harness: Includes 9-pin connector harness

Fits: Goodman/Amana GMNT090-4B and compatible furnaces

OEM vs. Generic

Control boards are model-specific — the OEM Goodman board ships with the correct firmware, relay ratings, connector layout, and 9-pin harness so timing and safety logic match your furnace exactly. Generic or cross-referenced boards risk incorrect blower timing, ignition faults, or connector mismatches. For a control board, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Power off at the breaker and photograph all connections first. Remove the blower-compartment panel, unplug each labeled harness, transfer wiring one plug at a time to the new board, and mount. Verify ignition sequence on startup. Allow 30–45 minutes; professional installation recommended if unsure.

Frequently Asked Questions

Does this Control Board fit my Goodman GMNT090-4B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMNT090-4B — 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 GMNT090-4B — 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.
