A fan center combines the blower relay with a 24V control transformer, switching the indoor blower on a call for heat or fan. If the blower won't energize, runs continuously, or the furnace has no 24V control power, a failed fan center is a common cause.\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 with integral 24V control transformer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Switches line-voltage blower from low-voltage thermostat\/control signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUI100-2 furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM fan center\u003c\/strong\u003e matches the original transformer VA rating, contact ratings, and terminal layout, so it drops in without re-wiring or load concerns. Universal fan centers can work but often differ in mounting and terminal arrangement, adding wiring time and the risk of an under-rated transformer that overheats.

Photograph existing wiring, cut power at the disconnect, and transfer leads one at a time to the matching terminals. Verify the transformer secondary reads 24V after power-up. Plan on 30–45 minutes; if you are unsure about the low-voltage control wiring, use a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058186010995,"sku":"GOODMAN-B1141702","price":85.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-fan-center-relay-for-gui100-2-furnace-b1141702","provider":"National HVAC Parts","version":"1.0","type":"link"}
