The Goodman B1393803 Single Wing PCB Support is a genuine OEM standoff clip used to mount the integrated furnace control board inside the GDH80403ANBB gas furnace. Unlike the double-wing version, this single-wing support grips one edge of the circuit board and is used at panel locations where only one-sided retention is needed, working together with the other standoffs to hold the PCB flat and off the metal chassis.

A cracked or missing single-wing support allows the control board to sag or shift, which can stress the board's connectors and traces and lead to intermittent operation. Fitting fresh supports whenever you replace a control board is inexpensive insurance against comeback service calls.

OEM vs. Generic

The OEM Goodman support delivers the precise snap-in fit intended for the GDH80403ANBB control panel. Our generic-equivalent alternative provides the same single-wing hold at a reduced price, perfect for stocking your service truck.

Installation Difficulty

Easy (1/5). No tools needed — release the old clip's tabs, pull it out, and press the new support into the sheet-metal slot until it locks. Always cut power to the furnace first, then seat the board edge into the wing.

Frequently Asked Questions

Does this Control Board Support fit my Goodman GDH80403ANBB — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman GDH80403ANBB — 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 GDH80403ANBB — 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.
