This fan center combines a 24-volt relay with an integrated transformer terminal block, controlling blower operation in response to thermostat and limit-control signals. When your furnace blower fails to start, runs continuously, or short-cycles, a failed fan center relay is one of the most common culprits.\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 (SPDT switching)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Gas furnace blower control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUI100-4 and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM part\u003c\/strong\u003e, built to the exact electrical and mechanical tolerances of your furnace.
