Goodman B1393803 Single Wing PCB Support

The Goodman B1393803 is a genuine OEM single wing PCB mounting support designed for the GMTH115-5 gas furnace and compatible Goodman/Amana units. It is typically used together with the double-wing support (B1393802) to fully secure the integrated furnace control board along a single edge, maintaining proper standoff clearance from the cabinet.

Specifications

Type: Single wing PCB standoff / mounting support
OEM Part Number: B1393803
Brand: Goodman
Fits Model: GMTH115-5 (and compatible furnace platforms)
Material: High-temp molded nylon standoff
Pairs With: B1393802 double wing support

OEM vs. Generic

OEM Goodman standoffs match the exact snap height and wing width required to hold the control board level and secure. Aftermarket generics are cheaper but inconsistent in fit, risking a board that rattles or seats at an angle. For reliable control-box mounting, OEM is recommended.

Installation Difficulty

Easy (1/5). Tool-free snap-in installation into the control-box knockout; the board edge clips onto the wing. Disconnect furnace power before servicing.

Frequently Asked Questions

Does this Control Board Support fit my Goodman GMTH115-5 — B1393803?

Yes. This is the factory-specified OEM control board support for the Goodman GMTH115-5 — 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 support on my Goodman GMTH115-5 — 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 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 control 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.
