The Goodman B1393803 Single Wing PCB Support is a genuine OEM mounting standoff for the ADSS800603AXAA furnace and compatible Goodman/Amana control assemblies. This single-wing support snaps into the control panel and holds one edge of the integrated furnace control board off the metal chassis, maintaining correct clearance to prevent electrical shorts, vibration, and fatigue on the board.

Specifications

Type: PCB mounting support / board standoff
Style: Single wing (one-tab locking base)
Function: Isolates and secures one edge of the control board
OEM Part Number: B1393803
Fits: Goodman ADSS800603AXAA and related furnace control boards

OEM vs. Generic

The OEM B1393803 is molded to the precise post height and hole diameter this furnace requires, so the control board seats flat and stays locked. Generic standoffs often differ in dimensions, leaving the board loose or under stress. The OEM part guarantees a secure, correctly spaced fit.

Install Difficulty

Easy (1/5). Snap-in replacement — disconnect power, release the old support's locking tab, press the new support into the panel, and clip the board onto it. No tools required. Commonly used together with the double wing support (B1393802) to fully mount the board.

Verify your furnace model number before ordering to ensure the correct mounting pattern.

Frequently Asked Questions

Does this Circuit Board Support fit my Goodman ADSS800603AXAA — B1393803?

Yes. This is the factory-specified OEM circuit board support for the Goodman ADSS800603AXAA — 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 ADSS800603AXAA — 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.
