Goodman B1393803 Single Wing PCB Support

The Goodman B1393803 Single Wing PCB Support is the genuine OEM standoff that anchors one corner or edge of the integrated furnace control board. It is used alongside the double-wing support to hold the board securely in the control box of the Goodman GDH80403ANBA and related 80% AFUE gas furnaces built on the same Goodman/Amana chassis. When a support snaps, the board can flex during cycling, stressing solder joints and connectors and causing intermittent no-heat faults.

Specifications

OEM Part Number: B1393803
Type: Single wing PCB / control board support
Material: Molded insulating standoff
Fits Model: GDH80403ANBA (and compatible Goodman/Amana furnaces)
Equipment: Gas Furnace, 80% AFUE
Brand: Goodman (genuine OEM)

OEM vs. Generic

Choosing the genuine Goodman OEM B1393803 ensures the retaining wing lines up with the board's mounting hole and clips positively into the cabinet. Aftermarket substitutes often use a mismatched wing height that leaves the board loose or bowed. Given the low price and safety role, OEM is the smart choice.

Installation Difficulty

Easy (1/5). Disconnect power, open the control panel, release the old support from the board and cabinet, and snap the replacement in. About 10 minutes with common tools. Verify the disconnect is off before starting.

Compatibility note: confirm your model/serial before ordering. Questions? info@nationalhvacparts.com.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman GDH80403 — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman GDH80403 — 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 GDH80403 — 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.
