The Goodman B1393803 Single Wing PCB Support is a genuine OEM standoff clip used to mount the integrated control board in the AMS81405DNBA and compatible Goodman/Amana gas furnaces. The single-wing design snaps into an edge slot on the control panel and supports one side of the board, working alongside double-wing supports (such as B1393802) to hold the PCB flat and away from the chassis.

Specifications

Part type: Single-wing PCB standoff / support clip
OEM Part Number: B1393803
Fits: Goodman/Amana AMS81405DNBA gas furnace
Configuration: One-sided (single wing) retention
Material: Non-conductive nylon
Brand: Goodman (OEM)

OEM vs. Generic

OEM single-wing supports match the panel slot spacing exactly, so the control board seats without flexing. Generic clips can be a hair off, leaving the board rocking and vulnerable to vibration cracks and nuisance faults. For a low-cost part that protects an expensive control board, OEM is the smart pick.

Install Difficulty

Easy (2/5). Snap-in replacement using basic hand tools. Disconnect furnace power before servicing and photograph the board layout first.

Frequently Asked Questions

Does this Control Board Support fit my Goodman AMS81405DNBA — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman AMS81405DNBA — 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 AMS81405DNBA — 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.
