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

The B1809913S is a genuine OEM integrated furnace control board, supplied with its 9-pin wiring harness, for the Goodman GMTH070-4B gas furnace and compatible Goodman/Amana models. This is the furnace's brain — it manages the ignition sequence, times the inducer and blower, monitors the flame sensor and limit circuit, and drives the gas valve. Symptoms of a failing board include no ignition, short-cycling, blower running constantly, or diagnostic fault codes on the onboard LED. Replacing it with the correct OEM control restores full, reliable operation.

Specifications

Part Number: B1809913S
Type: Integrated ignition control module (IFC)
Includes: 9-pin main wiring harness
Function: Ignition, blower/inducer timing, safety monitoring, diagnostics
Brand: Goodman (Amana compatible)
Equipment: Gas furnace — fits GMTH070-4B

OEM vs. Generic

The OEM Goodman B1809913S guarantees matched firmware timing, connector pinout, and the included 9-pin harness for a true plug-and-play swap. A generic/aftermarket equivalent can offer significant savings, but verify pinout and timing compatibility — for a critical ignition control, OEM is the safest choice.

Installation Difficulty

Moderate (3/5). Plan for 30–45 minutes. Photograph every wire connection first, then transfer plugs one at a time to the new board. Always disconnect power at the breaker before servicing. Because this control governs gas ignition and safety timing, a licensed HVAC technician is recommended if you're not experienced with furnace wiring.

Frequently Asked Questions

Does this Control Board fit my Goodman GMTH070-4B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMTH070-4B — 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 GMTH070-4B — 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.
