Goodman B1393803 Single Wing PCB Support

The B1393803 is a genuine OEM single-wing circuit-board support (standoff) for the Goodman/Amana AMS80804BXAB gas furnace. This nylon standoff snaps into the control panel and retains one edge of the integrated ignition control board, holding it firmly while insulating it from the metal cabinet. The single-wing design is used at board edges or where a one-sided clip is needed alongside double-wing supports.

Specifications

OEM Part Number: B1393803
Type: PCB standoff / control-board support, single wing
Material: High-temperature nylon
Function: Retains and isolates the furnace control board edge
Fits: Goodman & Amana AMS80804BXAB furnaces
Brand: Genuine Goodman OEM

OEM vs. Generic

As with all board standoffs, exact post height and snap geometry matter. This OEM single-wing support pairs correctly with the B1393802 double-wing supports used on the same panel, giving the board a secure, vibration-free mount. Generic substitutes rarely match the barb and wing profile.

Install Difficulty: Easy (⭐☆☆☆☆)

Hand-installed snap-in part — pop out the old support and press in the new one after freeing the board. Roughly 5–10 minutes. Always disconnect power before servicing.

Compatible with model AMS80804BXAB. Genuine OEM part, in stock and ready to ship.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman AMS80804BXAB Furnace — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman AMS80804BXAB 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 AMS80804BXAB 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.
