The Goodman B1393803 single wing PCB mounting support is a genuine OEM bracket that secures the integrated furnace control board inside AMS80603AXAC gas furnaces. When a control board is replaced, cracked mounting tabs or a missing support can leave the board loose and prone to vibration damage and intermittent electrical faults. This exact-fit bracket restores solid, factory-correct mounting.

Part number: B1393803
Type: Single wing PCB / control board mounting support
Fits: Goodman/Amana AMS80603AXAC and related 80% AFUE furnaces
Material: Molded thermoplastic standoff
Compatibility: OEM direct replacement

OEM vs. Generic

The OEM B1393803 is molded to exact factory dimensions so the board's mounting holes and locking tabs align on the first try. Generic universal standoffs may fit loosely, require drilling, or fail to lock, risking a shifting board. For a reliable, no-modification repair we recommend the genuine OEM part.

Installation Difficulty

Easy (1/5). Snaps into the sheet-metal chassis; no tools beyond disconnecting power. A 5-minute job for most homeowners and technicians. Always shut off power at the furnace switch before servicing.

Frequently Asked Questions

Does this Circuit Board Accessory fit my Goodman AMS80603AXAC — B1393803?

Yes. This is the factory-specified OEM circuit board accessory for the Goodman AMS80603AXAC — 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 accessory on my Goodman AMS80603AXAC — 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 accessory 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 accessory?

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.
