The genuine Goodman B1393802 is a double-wing PCB support, a molded mounting standoff that secures the integrated furnace control (circuit) board inside the GMTH070-4 and compatible Goodman/Amana furnace control boxes. Its two locking wings snap into the board's mounting holes and the cabinet, holding the PCB rigidly off the sheet metal to prevent shorts, vibration, and cracked solder joints.

Specifications

OEM Part Number: B1393802
Type: Double wing PCB / control board support standoff
Function: Isolates and secures the integrated furnace control board
Material: High-temperature nylon
Fits: Goodman GMTH070-4 and compatible furnace platforms
Brand: Goodman (OEM)

OEM vs. Generic

OEM supports are dimensioned to the exact board hole spacing and cabinet thickness so the PCB seats flush and the wings latch positively. Generic snap-in standoffs frequently have the wrong shoulder height or wing spread, leaving the board loose or under stress. Because a poorly supported board can crack and fail intermittently, matching the OEM part is the safe choice.

Installation Difficulty

Very Easy (1/5) — Power down the furnace, gently release the old support wings, and press the new B1393802 into place until both wings lock. No tools or wiring changes required. Replace supports in pairs if others show fatigue.

De-energize the furnace before opening the control box. Provide your full model and serial number if you need help confirming fit.

Frequently Asked Questions

Does this Furnace Control Board Support fit my Goodman GMTH070-4 — B1393802?

Yes. This is the factory-specified OEM furnace control board support for the Goodman GMTH070-4 — B1393802. 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 — B1393802?

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.
