This 16-position connector assembly links the integrated furnace control (IFC) board to the furnace's low- and line-voltage circuits — carrying signals for the gas valve, igniter, blower, limit switches, and thermostat inputs. When a harness develops melted pins, loose terminals, or heat-damaged insulation, the furnace can short-cycle, lock out, or fail to fire. A factory harness restores clean, reliable connections without the risk of miswiring.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1378700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 16-pin plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Control board wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GMN060-3 (confirm connector count on your board)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Amana compatible)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Color-coded, factory-terminated leads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause pin-out, gauge, and connector keying must match the control board exactly, we stock only the genuine OEM harness. Generic or hand-built harnesses risk incorrect pin assignment and are not recommended for the GMN060-3 control system.
