Goodman B1393803 Single-Wing PCB Support Bracket

The B1393803 is a genuine Goodman single-wing PCB support bracket engineered to hold the integrated furnace control board (IFC) firmly in place inside the control compartment. It is a direct-fit replacement for the AMS81405DNBC gas furnace and shares tooling across many Goodman and Amana multi-position air handlers and furnaces. A cracked, warped, or missing board support lets the control PCB flex under vibration, which can loosen edge connectors and cause intermittent no-heat faults.

Specifications

Type: Single-wing control board (PCB) support
OEM Part Number: B1393803
Primary Fit: Goodman AMS81405DNBC furnace
Material: Molded thermoplastic with integrated snap tabs
Brand: Goodman / Amana OEM

OEM vs. Generic

This is a true OEM Goodman component molded to the exact mounting-boss spacing of the original chassis. Generic or 3D-printed brackets often miss the snap-tab geometry, sit loose, and let the board rattle. Choosing OEM guarantees the board seats flush and the standoffs align on the first try.

Installation Difficulty

Easy (1 of 5). Power down the furnace at the disconnect, unclip the old support, transfer the control board, and snap the new bracket into place. No wiring changes and typically under 15 minutes. Always confirm 24V power is off before servicing the control board.

Frequently Asked Questions

Does this Control Board Bracket fit my Goodman AMS81405DNBC — B1393803?

Yes. This is the factory-specified OEM control board bracket for the Goodman AMS81405DNBC — 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 bracket on my Goodman AMS81405DNBC — 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 bracket 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 bracket?

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?
