The Goodman B1393803 is a genuine OEM single wing PCB support that mounts and secures the integrated furnace control board in the AMS80603AXAA and compatible Goodman/Amana furnaces. The single-wing standoff snaps into the chassis and locks one corner or edge of the circuit board at the correct height, working alongside the double-wing supports to hold the board rigid. This keeps the board off the sheet metal, prevents shorts, and absorbs blower vibration that would otherwise crack solder joints.

  • Part number: B1393803
  • Type: PCB support / control board standoff
  • Style: Single wing (single-point locking)
  • Fits: Goodman & Amana AMS80603AXAA and compatible furnaces
  • Material: High-temp nylon standoff
  • Sold as: Single support

OEM vs. Generic: The OEM B1393803 is molded to Goodman's exact board-hole and chassis dimensions for a firm, rattle-free grip. Generic standoffs often sit loose or snap during installation. For a secure board mount, choose the OEM part. Pairs with the double wing support (B1393802) on the same board.

Install difficulty: Easy (2/5). Power off, release the control board, pull the old support from the chassis, push in the new B1393803, and clip the board back onto the wing. About 10–15 minutes with no special tools. Confirm the board is held firmly before re-energizing.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman AMS80603AXAA Furnace — B1393803?
Yes. This is the factory-specified OEM circuit board support for the Goodman AMS80603AXAA Furnace — B1393803. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the circuit board support on my Goodman AMS80603AXAA Furnace — B1393803?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this circuit board support compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman circuit board support?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
