The Goodman B1141702 Fan Center Relay is a genuine OEM combined relay and 24-volt control transformer assembly built for the GUP060-3 gas furnace and compatible Goodman/Amana models. A fan center packages the blower switching relay together with the step-down transformer that powers the 24V thermostat circuit — so a single failure here can knock out both the low-voltage control and the blower operation. Symptoms of a bad fan center include a dead thermostat, a blower that won't start, or chattering contacts.
The OEM Goodman B1141702 provides the correct transformer VA rating and relay contact rating matched to the GUP060-3's control load, mounted on the factory bracket for a direct fit. Generic fan centers may under-supply VA or use a different footprint, forcing rewiring and risking an overloaded transformer. Because this part powers the entire control circuit, OEM is the safe choice.
Moderate (3/5) — About a 30–45 minute job. De-energize the furnace, label and photograph the line-voltage and 24V connections, transfer wiring to the matching terminals, and secure the assembly. Verify 24V transformer output and correct blower switching with a multimeter after installation.
