The Goodman B1393803 Single Wing PCB Support is a genuine OEM standoff that anchors one edge of the integrated furnace control board in your Goodman/Amana AMS80403AXAB gas furnace. It is typically used together with the double-wing support (B1393802) to fully brace the board within the control compartment. The single-wing profile fits tighter corner locations where a two-sided bracket will not clear surrounding wiring.

Specifications

Part Number: B1393803
Type: Single Wing PCB Support
Material: Molded thermoplastic standoff
Fits Model: AMS80403AXAB (multi-position gas furnace)
Function: Integrated control board (PCB) edge retention

OEM vs. Generic

Factory-original Goodman tolerances ensure the board seats flush and the snap tab locks securely. Off-brand supports frequently sit proud of the cabinet, allowing the board to flex under vibration and eventually fail. OEM is the reliable, drop-in choice.

Installation Difficulty

Easy (1/5) — Press-fits into the factory mounting hole; no tools needed. Cut power at the breaker before opening the control panel.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman AMS80403AXAB — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman AMS80403AXAB — 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 AMS80403AXAB — 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.
