The Goodman B1393802 Double Wing PCB Support is a genuine OEM mounting standoff for the integrated furnace control board on the AMS80403AXAA gas furnace and compatible Goodman and Amana models. This double-wing clip snaps into the control panel and holds the printed circuit board at the correct standoff height, keeping traces and solder joints isolated from the metal chassis and preventing vibration damage or short circuits. Broken or missing supports let the board flex, which can crack solder joints and cause intermittent control faults.

Specifications

OEM Part Number: B1393802
Compatible Model: AMS80403AXAA (and related Goodman/Amana furnaces)
Type: Double-wing PCB support / standoff
Function: Mounts and spaces the integrated control board
Material: Heat-resistant nylon

OEM vs. Generic

The OEM B1393802 matches the exact locking-tab spacing and standoff height of the AMS80403AXAA control panel, so the board seats securely without stress. Generic standoffs may not lock into the factory slots or hold the correct height. For proper board support, use the genuine OEM clip.

Installation Difficulty: Easy

Rated Easy — the support snaps into the panel and the board clips onto it, no tools required, in just a few minutes. De-energize the furnace before handling the control board to avoid static or shock damage.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman AMS80403AXAA — B1393802?

Yes. This is the factory-specified OEM circuit board support for the Goodman AMS80403AXAA — B1393802. 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 AMS80403AXAA — B1393802?

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.
