Goodman B1393803 Single Wing PCB Support Bracket

The Goodman B1393803 is a genuine OEM single wing PCB (printed circuit board) support bracket designed to securely mount the integrated furnace control board inside Goodman GMTH045-3 furnaces and compatible models. This small but critical component keeps the control board rigidly positioned, preventing vibration damage, loose connections, and intermittent electrical faults that can cause no-heat conditions.

Specifications

Part Number: B1393803
Type: Single wing PCB / circuit board support bracket
Material: Formed steel with insulating standoff
Fits: Goodman GMTH045-3 gas furnaces
Function: Secures integrated furnace control module
Brand: Goodman (OEM)

OEM vs. Generic

The genuine Goodman OEM bracket is stamped to exact factory tolerances so the mounting tabs and standoff heights line up perfectly with the original board and cabinet holes. Aftermarket brackets often require bending or drilling and can leave the board improperly grounded. For a reliable, drop-in repair we recommend the OEM part.

Installation Difficulty

Easy (1/5) — Disconnect furnace power, slide the old bracket out, and seat the replacement. Typically a 5–10 minute job requiring only a nut driver. Always shut off power at the disconnect before servicing.

Compatible with Goodman GMTH045-3. Confirm your model and existing part number before ordering.
