The B1393802 is a genuine OEM double-wing PCB support for the Goodman/Amana ADV80905CXA gas furnace and compatible models. This molded standoff/bracket snaps into the control-board cavity and holds the integrated furnace control (PCB) at the correct height and spacing away from the sheet-metal cabinet. The dual-wing design locks the board on two edges, preventing flex, vibration cracks, and shorting against the chassis.
The OEM support matches the exact snap geometry and standoff height of the ADV80905CXA control cavity, so the board seats flush and its mounting holes line up. Generic plastic standoffs rarely match the two-wing footprint, leaving the board loose or improperly grounded. The genuine Goodman part restores a secure, factory-correct mount.
Cut power to the furnace before servicing the control board. Release the board from the old supports, unclip or unscrew the damaged standoff from the cabinet, press the new B1393802 into place, and re-seat the PCB until the wings lock. No wiring changes are required — about 10–15 minutes. Confirm the board is firmly retained before restoring power.
