The fan center combines a switching relay with an integral 24V control transformer, energizing the line-voltage blower motor on a thermostat call while isolating the low-voltage control side. It manages both heating and cooling blower operation, making it a central component of the furnace's control sequence. Symptoms of failure include a blower that won't start, runs continuously, or chatters.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Fan center relay with control transformer\u003c\/li\u003e\n\u003cli\u003eControl voltage: 24V\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDI150-5 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1141702\u003c\/li\u003e\n\u003cli\u003eFunction: Switches blower motor on thermostat demand\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e fan center is pre-wired to the GDI150-5's connector layout and transformer VA rating.
