Goodman PCBFM103S Time Delay Relay Board

The Goodman PCBFM103S is a genuine OEM fan time-delay relay control board for the ATUF374316AA air handler and compatible Goodman/Amana units. It manages blower on/off timing, providing the built-in delay that improves comfort and efficiency by clearing residual heating/cooling from the coil before the blower stops.

Specifications

Function: Fan blower time-delay relay control
Type: Printed circuit control board (PCB)
Equipment: Air Handler
Fits model: ATUF374316AA
OEM part number: PCBFM103S

OEM vs. Generic

The OEM PCBFM103S guarantees correct timing logic, terminal layout, and voltage handling for your exact unit. Generic boards may require rewiring or jumper changes and can mis-time the blower, leading to short cycling or comfort complaints. OEM drops in without guesswork.

Install Difficulty

Moderate — Plug-in connectors make swaps straightforward, but you must photograph and match wiring exactly. Disconnect all power before replacing. Recommended for a qualified technician.

Frequently Asked Questions

Does this Control Board fit my Goodman ATUF374316AA — PCBFM103S?

Yes. This is the factory-specified OEM control board for the Goodman ATUF374316AA — PCBFM103S. 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 on my Goodman ATUF374316AA — PCBFM103S?

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 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?

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.
