The Goodman B1393803 Single Wing PCB Support is the genuine OEM mounting bracket that secures the integrated furnace control board inside the AMS80804BXAC multi-speed furnace. This small but critical part keeps the printed circuit board rigidly positioned so its wiring harness connectors, terminals, and standoffs stay properly aligned and free from vibration during blower operation. A cracked or missing support can let the board flex, leading to intermittent connections and nuisance fault codes.

Specifications

Part Number: B1393803
Type: Single wing PCB / control board support bracket
Fits Model: AMS80804BXAC (80% AFUE, 80,000 BTU multi-speed furnace)
Material: Formed galvanized steel

OEM vs. Generic

The OEM B1393803 is stamped to the exact factory dimensions, so the board's mounting holes line up on the first try and the wing engages the furnace panel cleanly. Aftermarket brackets are often close but not identical, forcing you to bend tabs or re-drill — extra time and a weaker hold. For a part this inexpensive, the genuine Goodman piece is the smart choice.

Installation Difficulty

Easy (1/5). Power down the furnace, unclip the control board, swap the bracket, and remount. No wiring changes required. Typically a 10-minute job with a nut driver. Always disconnect power before servicing.
