Goodman B1393803 Single Wing PCB Support

The B1393803 single-wing PCB support is a genuine OEM standoff bracket used to mount the integrated control board inside the Goodman/Amana AMS80403AXAC gas furnace. Paired with the double-wing support, this single-wing standoff anchors the opposite edge of the printed circuit board, keeping it rigid and electrically isolated from the metal cabinet. Replacing a broken or missing support with the exact OEM part prevents board flex, connector fatigue, and nuisance faults caused by a loose control board.

Specifications

OEM Part Number: B1393803
Part Type: Single-Wing PCB Support / Board Standoff
Fits Model: AMS80403AXAC and compatible Goodman/Amana furnaces
Brand: Goodman (Amana family)
Application: Integrated furnace control board mounting
Configuration: One-wing (single) mount

OEM vs. Generic

Aftermarket standoffs often miss Goodman's clip pitch and can sag under heat, letting the board shift against the cabinet. The genuine B1393803 uses factory geometry and high-temp material so the board stays fixed and correctly spaced.

Installation Difficulty

Easy (2/5). Snap-in replacement; a nut driver may help access the control panel. Disconnect power before servicing.
