The Goodman B1393803 Single Wing PCB Support is a genuine OEM mounting standoff for the Amana/Goodman AMS81005CXAA furnace. This single-wing snap-in support secures one edge of the integrated furnace control board (PCB) within the control box, maintaining proper standoff height and keeping the board isolated from the metal chassis. When a support cracks or is lost during service, the board can flex or vibrate, leading to intermittent electrical faults or damaged traces.

Specifications

Part type: PCB mounting support / standoff
Style: Single wing (one retention tab)
Function: Locates and isolates one edge of the control board
Material: Heat-resistant nylon
OEM part number: B1393803
Primary fit: Amana/Goodman AMS81005CXAA furnace

OEM vs. Generic

The genuine OEM B1393803 is dimensioned to the factory board and chassis slots. Generic standoffs may not retain the tab securely or match the hole size, leaving the board loose. Given the low cost, the OEM part is the reliable choice for a solid board mount.

Install Difficulty

Easy (1 of 5). Cut power to the furnace, release the worn support, and snap the new single-wing support into its chassis slot. No tools are normally needed. Frequently paired with the double-wing support (B1393802) — replacing both at once ensures the control board is fully and evenly seated.

Frequently Asked Questions

Does this Control Board Support fit my Goodman AMS81005CXAA — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman AMS81005CXAA — 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 AMS81005CXAA — 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.
