The Goodman B1393803 Single Wing PCB Support is the genuine OEM mounting standoff used to secure the integrated furnace control board in the GDH80403AXBB. Its single-wing profile clips one edge of the PCB where a full double-wing support won't fit, keeping the board firmly spaced off the cabinet to prevent electrical shorts and vibration wear. It is commonly used together with the double-wing support (B1393802).

  • Part number: B1393803
  • Type: Single-wing control board (PCB) support / standoff
  • Fits: Goodman GDH80403AXBB (verify by serial)
  • Function: Retains one edge of the furnace control board
  • Material: High-temp molded nylon

OEM vs. Generic: The OEM B1393803 is dimensioned to Goodman's factory panel slots and board thickness. Generic clips seldom seat cleanly, leaving the board loose — the OEM part guarantees correct alignment.

Install difficulty: Easy (2/5). Snap the support into the panel and clip the board edge; no tools required. Cut power before servicing and confirm compatibility before ordering.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman GDH80403AXBB — B1393803?
Yes. This is the factory-specified OEM circuit board support for the Goodman GDH80403AXBB — B1393803. 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 circuit board support on my Goodman GDH80403AXBB — B1393803?
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 circuit board support 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 circuit board support?
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.
How fast does National HVAC Parts ship?
