It combines the blower control relay and 24V control transformer functions into a single assembly, switching line-voltage blower operation on a low-voltage thermostat signal. When your furnace blower fails to energize on a call for heat or cooling, a failed fan center is one of the most common culprits.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1141702\u003c\/li\u003e\n\u003cli\u003eType: Fan Center Relay (SPST)\u003c\/li\u003e\n\u003cli\u003eCoil Voltage: 24V\u003c\/li\u003e\n\u003cli\u003eContact Rating: Line voltage blower switching\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUP100-4A furnace\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a true Goodman OEM component built to factory tolerances for exact fit, correct contact rating, and reliable low-voltage pickup.
