Goodman B1393803 Single Wing PCB Support

The B1393803 is a genuine OEM single-wing PCB (printed circuit board) support used to mount the integrated furnace control board in Goodman and Amana ADSS800403AXAA gas furnaces. The single-wing standoff pairs with the double-wing support to hold the control board securely along one edge, keeping it clear of the metal chassis and dampening vibration. A broken support lets the board flex and can produce intermittent, hard-to-diagnose control faults; the OEM part restores a solid mount.

Specifications

Part number: B1393803
Type: Single-wing PCB / control board support standoff
Compatibility: Goodman/Amana ADSS800403AXAA furnace
Material: Molded nylon, non-conductive
Mounting: Snap-in, single-side board retention

OEM vs. Generic

This genuine OEM support is dimensioned to the ADSS800403AXAA control panel and works together with the B1393802 double-wing support. Generic parts rarely match the clip height, so the board can sit unevenly. For correct board seating, use the OEM component.

Installation Difficulty

Easy (1/5). Snap-in replacement with the furnace powered off. No special tools required.

Frequently Asked Questions

Does this Control Board Support fit my Goodman ADSS800403AXAA — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman ADSS800403AXAA — 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 control board support on my Goodman ADSS800403AXAA — 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 control 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 control 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.
