The Goodman B1393803 Single-Wing PCB Support is a genuine OEM mounting standoff that helps secure the integrated furnace control board (PCB) inside the ADV80703BXA gas furnace and compatible Goodman/Amana models. This single-wing bracket snaps into the control box and retains one edge of the circuit board, working alongside the double-wing support (B1393802) to hold the board flat and isolated from the metal chassis. A missing or broken standoff lets the board vibrate and flex, which can fatigue solder joints and cause intermittent control faults.

Specifications

Part type: Single-wing PCB / control board support standoff
OEM part number: B1393803
Fits: Goodman ADV80703BXA furnace
Material: Molded nylon, non-conductive
Style: Single-wing (one-sided) snap retainer

OEM vs. Generic

The OEM Goodman support is molded to the exact clip geometry and standoff height of the original so the board sits at the correct clearance from the chassis. Generic standoffs often won't lock into the Goodman control box or match the board slot — OEM ensures a secure, insulated hold.

Installation Difficulty

Easy (1 of 5) — 10 minutes. Cut furnace power, release the board from the old support, press the new B1393803 into place, and re-seat the PCB. Typically no tools required.

Frequently Asked Questions

Does this Control Board Mount fit my Goodman ADV80703BXA — B1393803?

Yes. This is the factory-specified OEM control board mount for the Goodman ADV80703BXA — 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 control board mount on my Goodman ADV80703BXA — 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 control board mount 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 control board mount?

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.
