This harness delivers power from the integrated furnace control board to the hot surface igniter using the correct gauge wire and factory-keyed connectors. Heat cycling near the burner compartment can eventually harden insulation, loosen terminals, or char connectors — causing intermittent no-heat faults and failed ignition. Replacing the harness with this OEM assembly restores a clean, reliable connection to the igniter.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 2568416\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e HSI (Hot Surface Igniter) Wiring Harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GMPH120-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e High-temperature insulated leads, keyed plug-and-play connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman harness uses the exact connector type, pin-out, and heat-rated wire the furnace was designed around, so it plugs in without splicing or crimping. Generic wire kits require cutting and manual connections that can introduce resistance, corrosion, and future no-heat calls. OEM ensures a correct, code-friendly fit.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Shut off power and gas, remove the burner compartment door, unplug the old harness at the control board and igniter, route the new harness the same way, and reconnect the keyed plugs.
