This is the furnace's brain — it manages the ignition sequence, times the inducer and blower, monitors the flame sensor and limit circuit, and drives the gas valve. Symptoms of a failing board include no ignition, short-cycling, blower running constantly, or diagnostic fault codes on the onboard LED. Replacing it with the correct OEM control restores full, reliable operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1809913S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Integrated ignition control module (IFC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 9-pin main wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Ignition, blower\/inducer timing, safety monitoring, diagnostics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Amana compatible)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace — fits GMTH070-4B\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B1809913S\u003c\/strong\u003e guarantees matched firmware timing, connector pinout, and the included 9-pin harness for a true plug-and-play swap.

Because this control governs gas ignition and safety timing, a licensed HVAC technician is recommended if you're not experienced with furnace wiring.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058166448499,"sku":"GOODMAN-12559","price":229.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-furnace-control-board-for-gmth070-4b-b1809913s","provider":"National HVAC Parts","version":"1.0","type":"link"}
