A fan center combines a 24V relay and an integrated control transformer in one housing, providing the low-voltage power and blower switching your furnace needs to operate the indoor fan on heating and cooling calls. When the blower won't start—or runs continuously—a failed fan center is a frequent culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRelay coil voltage: 24V AC\u003c\/li\u003e\n\u003cli\u003eIntegrated step-down control transformer\u003c\/li\u003e\n\u003cli\u003eType: Fan center relay assembly\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GUP075-3A furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1141702\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM B1141702\u003c\/strong\u003e matches the factory transformer VA rating and relay contact spec, so it powers the control circuit without overloading or nuisance tripping.
