Goodman B1393803 Single Wing PCB Support

The Goodman B1393803 is a genuine OEM single-wing PCB support (circuit-board standoff/mounting clip) for the Goodman/Amana AMS80603AXAB gas furnace. This snap-in nylon standoff raises and secures the integrated furnace control board against the sheet-metal chassis, keeping the electronics insulated from the metal and free of vibration that could crack solder joints or cause shorts. The single-wing design provides a one-tab capture point, typically used alongside double-wing supports to fully seat the board. Cracked or missing standoffs are a frequent cause of a loose, rattling control board and intermittent faults.

Specifications

OEM vs. Generic

Genuine Goodman standoffs match the factory board-hole spacing and panel thickness for a secure snap fit. Generic substitutes may sit loose or become brittle in the furnace's heat, allowing the board to move and risking electrical faults. Replace paired supports together for balanced board mounting.

Installation Difficulty

Easy (2/5). Disconnect power, unclip the control board, remove the failed support, press in the new B1393803, and reseat the board. About 10–15 minutes.

Frequently Asked Questions

Does this Control Board Support fit my Goodman AMS80603AXAB — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman AMS80603AXAB — 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 AMS80603AXAB — 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.
