A fan center combines a 24-volt control relay with an integral control transformer, providing the low-voltage power and blower switching that link your thermostat to the furnace. When the blower won't energize, the thermostat is dead, or you have no 24V control power, a failed fan center is a common cause. The OEM assembly restores proper relay switching and transformer output in one part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1141702\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fan center relay \/ transformer assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil \/ Control Voltage:\u003c\/strong\u003e 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Blower relay switching + 24V control power\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Amana\/Janitrol family)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e GUP040-2 gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine B1141702 pairs the correct transformer VA rating with a relay matched to the furnace blower load and uses the factory terminal layout for a wire-for-wire swap.
