OEM vs. Generic

The genuine B1809913S is pre-flashed with the exact ignition timing, blower delays, and safety logic Goodman certified for this furnace. Aftermarket or unbranded boards can mismatch fan on/off delays, misread the flame signal, or void warranty coverage. For a heating appliance, the OEM board is the safe, reliable choice.

Installation Difficulty

Advanced (4 of 5). Shut off power and gas. Photograph all connections, transfer wiring one lead at a time to the new board, and mount using the existing standoffs. Verify line polarity and ground, then run a full heat cycle and confirm no fault codes. Professional installation recommended for anyone unfamiliar with furnace control wiring.

Restore reliable, safe operation to your GMTH090-5B with genuine Goodman control electronics.

Frequently Asked Questions

Does this Control Board fit my Goodman GMTH090-5B — B1809913S?

Yes. This is the factory-specified OEM control board for the Goodman GMTH090-5B — 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 GMTH090-5B — 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.
