This board is the brain of the furnace — it sequences the inducer, hot surface ignitor, gas valve, and blower while monitoring safety limits and the flame sensor. Symptoms of a failed board include no response to the thermostat, blower running constantly, error-code LED faults, or ignition lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Integrated furnace control board (IFC)\u003c\/li\u003e\n\u003cli\u003eControls: Inducer, HSI, gas valve, blower heat\/cool timing\u003c\/li\u003e\n\u003cli\u003eDiagnostics: On-board LED fault codes\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUS075-3 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1809904S\u003c\/li\u003e\n\u003cli\u003eInput: 120V line \/ 24V control circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e board carries the exact firmware, timing tables, and connector pinout the GUS075-3 was designed around. Because control boards drive gas and ignition sequencing, we do not recommend generic substitutes — a mismatched board can cause unsafe timing or persistent lockouts. OEM ensures correct, safe operation.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRequires transferring wiring harnesses one connector at a time to the matching terminals. Photograph the original wiring first. Best handled by an HVAC professional; plan on 45–60 minutes. Disconnect all power before removing the old board.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058198856051,"sku":"GOODMAN-13344","price":191.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-furnace-control-board-for-gus075-3-b1809904s","provider":"National HVAC Parts","version":"1.0","type":"link"}
