This harness carries the low-voltage and ignition signals between the furnace control board and the ignition\/sensing components. A cracked connector, melted pin, or chafed lead can cause intermittent no-heat calls, ignition lockouts, or nuisance faults — replacing the harness restores a clean, corrosion-free electrical connection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConfiguration: 5-pin keyed connector\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNT080-4 and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eType: Low-voltage ignition\/control harness\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1378701\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM harnesses use factory-spec connectors and wire gauge that seat correctly and are rated for furnace-cabinet temperatures.
