Goodman B1393803 Single Wing PCB Support

This genuine OEM single-wing PCB support secures the control board in your Goodman/Amana AMS80805CXAB furnace. The nylon standoff snaps into the chassis and holds the integrated furnace control board at the proper height, isolating it from the metal panel to prevent shorts and vibration wear. The single-wing profile is used at board edges and tighter locations where the double-wing support won't fit. Cracked supports are a common cause of a loose or buzzing control board — this inexpensive part restores a solid mount.

Specifications

Part Number: B1393803
Type: Single-wing snap-in PCB support / standoff
Fits Model: AMS80805CXAB and compatible Goodman/Amana furnaces
Function: Secures and spaces the furnace control board
Material: Heat-resistant nylon

OEM vs. Generic

The OEM B1393803 is molded to the exact single-wing geometry and hole spacing of this chassis so it snaps in and grips reliably. A generic standoff can substitute, but OEM ensures correct fit and retention where board clearance is tight. Often paired with the B1393802 double-wing support.

Installation Difficulty

Very Easy (1/5). Snap-in — no tools required. Swap the broken support and re-seat the board in under 5 minutes. Disconnect power before servicing.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman AMS80805CXAB — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman AMS80805CXAB — 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 AMS80805CXAB — 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.
