Goodman PCBFM103S Time Delay Relay Board

The Goodman PCBFM103S is the OEM blower fan time-delay relay control board for the GPC1336H21A packaged air conditioner. This board manages indoor blower operation and the on/off fan delay that improves efficiency and prevents abrupt temperature swings. When the blower won't start, runs continuously, or ignores the thermostat fan call, a failed control board is a leading cause. The factory board restores correct timing and reliable fan sequencing.

Specifications

Type: integrated fan / time-delay relay control board
Function: blower control with on/off fan delay timing
Voltage: 24V control with line-voltage blower relay
Mounting: OEM stand-off / connector layout
Fit: Goodman GPC1336H21A air conditioner
OEM part number: PCBFM103S

OEM vs. Generic

The OEM PCBFM103S matches Goodman's exact connector pinout, relay ratings, and delay logic for plug-and-play replacement. Generic or rewired boards risk incorrect timing, connector mismatches, and damage to the blower motor. The OEM board is the dependable, warranty-safe fit.

Installation Difficulty

Intermediate (3/5). Disconnect power, photograph wiring, transfer connectors one at a time to the new board, and confirm the fan delay operates on a thermostat call. A licensed HVAC technician is recommended for diagnosis and wiring verification.

Frequently Asked Questions

Does this Control Board fit my Goodman GPC1336H21A — PCBFM103S?

Yes. This is the factory-specified OEM control board for the Goodman GPC1336H21A — 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 GPC1336H21A — 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.
