Goodman B1393803 Single Wing PCB Support Bracket

The B1393803 is a genuine Goodman single wing PCB (printed circuit board) support bracket built for the ADV81155CXA furnace and compatible Goodman/Amana gas furnace models. It works alongside the double wing bracket to anchor the integrated furnace control board, keeping the module rigid, correctly spaced, and properly grounded inside the control compartment.

Specifications

OEM Part Number: B1393803
Type: Single wing PCB support bracket
Fits Model: ADV81155CXA (and compatible Goodman/Amana furnaces)
Function: Control board mounting / standoff support

OEM vs. Generic

The single wing B1393803 is designed to pair with its matching double wing counterpart for a balanced, factory-correct mount. OEM brackets align with the original standoffs and hole pattern so the board sits flat with no flex. Generic substitutes typically need modification and can leave the board vibrating or improperly grounded, risking premature control failure.

Installation Difficulty

Easy (1/5). A basic mechanical replacement using a nut driver or screwdriver — no special tools required. Disconnect electrical power and shut off the gas supply before servicing. When in doubt about the control board wiring, call a qualified HVAC professional.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman ADV81155CXA — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman ADV81155CXA — 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 ADV81155CXA — 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.
