The Goodman PCBFM103S Time Delay Relay Board is a genuine OEM control component engineered for the ATUF182416AA air handler and compatible Goodman/Amana fan-coil units. This integrated fan control board manages blower motor operation, providing the timed on/off delay that improves comfort and protects the blower motor from short-cycling. When your air handler's fan fails to start, runs continuously, or stops responding to thermostat calls, a failed relay board is one of the most common causes.

OEM vs. Generic

The OEM PCBFM103S guarantees exact terminal pinout, relay timing, and amperage ratings validated by Goodman for the ATUF series — eliminating guesswork and warranty risk. Lower-cost generic boards may approximate the form factor but can introduce timing mismatches and inconsistent relay quality. For control electronics, we strongly recommend OEM.

Installation Difficulty: Moderate

Replacement requires disconnecting power at the breaker, photographing and transferring the low-voltage and line-voltage harness connections to the matching terminals, and securing the board to its standoffs. Most experienced DIYers complete this in 30–45 minutes; if you are not comfortable working with 24V and 120/240V wiring, hire a licensed HVAC technician. Always confirm power is off before servicing.

Frequently Asked Questions

Does this Relay Board fit my Goodman ATUF182416AA — PCBFM103S?

Yes. This is the factory-specified OEM relay board for the Goodman ATUF182416AA — 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 relay board on my Goodman ATUF182416AA — 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 relay 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 relay 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.
