Constant heat cycling near the burner assembly makes this harness a common failure point — melted insulation, corroded pins, or a cracked connector housing can cause intermittent no-heat calls, igniter dropouts, and hard-lockout faults that mimic a bad igniter or control board.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eApplication: Hot surface igniter (HSI) circuit\u003c\/li\u003e\n\u003cli\u003eConnector: Factory keyed plug, direct-fit to GMP-series board and igniter\u003c\/li\u003e\n\u003cli\u003eWire: High-temperature insulated leads rated for burner-box heat\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana GMP075-3 and compatible models\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 2568416\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM harness\u003c\/strong\u003e arrives pre-terminated with the correct keyed connectors, so it plugs straight in — no cutting, crimping, or guessing at pin-outs.

Kill power at the furnace, photograph the routing, unplug the old harness at both ends, and clip the new one into place along the same path away from sharp edges and hot surfaces. Restore power and cycle a heat call to confirm ignition.
