The Goodman B1393803 Single-Wing PCB Support is the genuine OEM nylon standoff that mounts and isolates the integrated furnace control (circuit) board inside the ADSH800403AXAA and compatible Goodman/Amana models. The single-wing locking design snaps into the chassis and grips the board at one point, and is typically used alongside the double-wing support (B1393802) to fully secure the board off the metal panel. Broken or missing supports let the board sag, vibrate, or short against the cabinet.

Specifications

Part number: B1393803
Type: PCB / control board support standoff
Style: Single-wing locking clip
Fits model: ADSH800403AXAA furnace
Brand: Goodman (OEM)
Material: Heat-resistant nylon

OEM vs. Generic

This is a genuine OEM Goodman support sized to the exact panel cutout and board hole spacing. Generic standoffs rarely match the locking geometry and can leave the board loose. Use the OEM part — and pair it with the double-wing B1393802 — for a secure, rattle-free mount.

Installation Difficulty

Very easy (1/5). Power off the furnace, release the old support, snap the new one into the chassis, and seat the board onto it. No tools required, under 5 minutes.
