The Goodman B1141702 is a genuine OEM fan center relay for the Goodman GUI100-2 gas furnace. A fan center combines the blower relay with a 24V control transformer, switching the indoor blower on a call for heat or fan. If the blower won't energize, runs continuously, or the furnace has no 24V control power, a failed fan center is a common cause.

Specifications

Part number: B1141702
Type: Fan center relay with integral 24V control transformer
Function: Switches line-voltage blower from low-voltage thermostat/control signal
Coil: 24V
Fits: Goodman GUI100-2 furnace
Brand: Goodman OEM

OEM vs. Generic

The genuine Goodman OEM fan center matches the original transformer VA rating, contact ratings, and terminal layout, so it drops in without re-wiring or load concerns. Universal fan centers can work but often differ in mounting and terminal arrangement, adding wiring time and the risk of an under-rated transformer that overheats. The OEM part is the clean, reliable swap.

Installation Difficulty

Moderate. Involves both line-voltage and 24V low-voltage connections. Photograph existing wiring, cut power at the disconnect, and transfer leads one at a time to the matching terminals. Verify the transformer secondary reads 24V after power-up. Plan on 30–45 minutes; if you are unsure about the low-voltage control wiring, use a licensed HVAC technician.
