The Goodman PCBFM103S Time Delay Relay Board is a genuine OEM blower control board for GPC1342H21A packaged air conditioners. This board manages the indoor blower motor's timed fan-on and fan-off delays, improving comfort and efficiency by allowing the coil to fully energize before airflow starts and by purging residual conditioned air at the end of a cycle. A failed board commonly shows up as a blower that won't start, won't stop, or short-cycles.

Specifications

Part type: Fan/blower time-delay relay control board
OEM part number: PCBFM103S
Brand: Goodman (genuine OEM)
Fits: GPC1342H21A package air conditioner

Onboard relay for indoor blower motor switching

OEM vs. Generic

The OEM PCBFM103S arrives pre-programmed with Goodman's exact delay timing and uses connectors that match the factory wiring harness for a true plug-and-play swap. Generic or rebuilt boards may use different timing logic or relay ratings, leading to nuisance trips and premature blower wear. For a reliable, warranty-grade repair, install the genuine board.

Installation Difficulty

Moderate — Disconnect power at the breaker, photograph the existing wiring, transfer connectors one at a time to the new board, and mount it in the original location. Basic electrical knowledge required. If you are not comfortable working around live line voltage, have a licensed HVAC technician perform the replacement.

Frequently Asked Questions

Does this Control Board fit my Goodman GPC1342H21A — PCBFM103S?

Yes. This is the factory-specified OEM control board for the Goodman GPC1342H21A — 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 GPC1342H21A — 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.
