The genuine Goodman B1393803 is a single-wing PCB support, a molded standoff used to mount and isolate the integrated furnace control board in the GMTH070-4 and compatible Goodman/Amana furnace control boxes. It works alongside the double-wing supports (such as B1393802) to hold the PCB securely off the cabinet, preventing electrical shorts and vibration-related board damage.

Specifications

OEM Part Number: B1393803
Type: Single wing PCB / control board support standoff
Function: Secures and isolates the integrated furnace control board
Material: High-temperature nylon
Fits: Goodman GMTH070-4 and compatible furnace platforms
Brand: Goodman (OEM)

OEM vs. Generic

The OEM single-wing support matches the board's hole diameter and the exact standoff height Goodman engineered for this control box, so the PCB sits level and latches firmly. Aftermarket universal standoffs often fit loosely or sit too tall, leaving the board unsupported at one corner. For reliable long-term mounting, OEM is recommended.

Installation Difficulty

Very Easy (1/5) — Shut off power to the furnace, release the worn support, and snap the new B1393803 into the board and cabinet until the wing locks. No tools or rewiring needed. Inspect neighboring supports and replace any that are brittle or cracked.

Always de-energize the furnace before servicing the control box. Contact us with your model and serial number to confirm fit.

Frequently Asked Questions

Does this Furnace Control Board Support fit my Goodman GMTH070-4 — B1393803?

Yes. This is the factory-specified OEM furnace control board support for the Goodman GMTH070-4 — 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 furnace control board support on my Goodman GMTH070-4 — 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 furnace 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 furnace 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.
