The Goodman B1809904S Integrated Furnace Control Board is the genuine OEM brain of the GUS125-5 gas furnace. This board manages the ignition sequence, blower timing, safety limits, and flame sensing. When it fails, symptoms range from no heat and a dead blower to erratic short-cycling or blinking diagnostic LEDs. Replacing it with the factory-matched control restores full, safe furnace operation.

OEM Part Number: B1809904S
Brand: Goodman
Fits Model: GUS125-5 (gas furnace)
Type: Integrated furnace control (IFC) board
Functions: Ignition timing, blower on/off delays, safety limit monitoring, flame sense
Diagnostics: Onboard LED fault codes for quick troubleshooting
Fit: Direct OEM replacement with matching harness plugs

OEM vs. Generic: The genuine B1809904S is pre-loaded with the exact firmware, relay ratings, and connector pinout the GUS125-5 expects. Aftermarket or cross-referenced boards may need jumper changes or adapter harnesses and can mis-time the blower, causing nuisance limit trips. For a safety-critical control, the OEM board is the reliable, warranty-safe choice.

Install Difficulty: Moderate (3 of 5). Cut power at the breaker first. Photograph the wiring, transfer each plug one at a time to the new board, and confirm the model-specific settings. Basic electrical familiarity recommended; budget 30–45 minutes. If unsure, use a licensed HVAC technician.

Frequently Asked Questions

Does this Control Board fit my Goodman GUS125-5 — B1809904S?

Yes. This is the factory-specified OEM control board for the Goodman GUS125-5 — B1809904S. 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 GUS125-5 — B1809904S?

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.
