This board is the brain of the furnace — it manages the ignition sequence, times the inducer and blower, monitors the flame sensor and limit switches, and drives the diagnostic LED fault codes.\u003c\/p\u003e\u003cp\u003eSymptoms of a failing control board include no ignition, short cycling, blower running continuously, blank or rapidly flashing diagnostic LEDs, and blown low-voltage fuses.

Aftermarket “universal” boards may need jumper reconfiguration and adapter harnesses, and a wrong timing profile can cause unsafe operation or repeated lockouts.

Photograph every wire connection before removal, cut power at the disconnect, transfer the harness plugs one at a time, and match the board orientation. Because this involves 120V and low-voltage wiring, homeowners uncomfortable with electrical work should hire a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058132599155,"sku":"GOODMAN-11776","price":184.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-furnace-control-circuit-board-for-gmnt120-5d-b1809913s","provider":"National HVAC Parts","version":"1.0","type":"link"}
