Goodman B1393803 Single Wing PCB Support

The Goodman B1393803 is a genuine OEM single wing PCB support built as a direct-fit replacement for the Goodman ADSH800804BXAA gas furnace and other compatible models. This nylon standoff anchors one edge of the integrated furnace control board, holding it firmly against vibration while keeping the required air gap from the metal cabinet. It is commonly paired with the double wing support (B1393802) to fully secure the board.

Specifications

OEM Part Number: B1393803
Brand: Goodman
Component: Single wing circuit board support / standoff
Compatible Model: ADSH800804BXAA (and select Goodman furnaces)
Style: One-wing snap-lock retainer
Material: Heat- and flame-rated nylon
Fit Type: Direct OEM replacement

OEM vs. Generic

Genuine OEM supports match the exact standoff height and wing profile so the board seats flush and locks without stressing the plastic. Generic alternatives often crack during installation or fail to grip, allowing the board to rattle loose over time. Choosing OEM guarantees a proper, lasting mount.

Installation Difficulty

Very Easy (1/5) — Unclip the failed support, discard it, and press the new B1393803 into the mounting slot before reseating the board edge. No tools required. Always disconnect power before servicing.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman ADSH800804BXAA Furnace — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman ADSH800804BXAA Furnace — 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 ADSH800804BXAA Furnace — 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.
