The Goodman 2568416 HSI Wiring Harness is the factory wiring assembly that connects the hot surface igniter to the integrated furnace control board on GMPH075-4 gas furnaces. Over years of heating cycles the harness endures repeated thermal stress near the burner compartment, and cracked insulation, burnt connectors, or brittle wire strands are a common cause of intermittent no-ignition faults. This genuine OEM harness restores a clean, reliable electrical path with the correct factory terminals and pin spacing.

Specifications

Part number: 2568416
Type: Hot surface igniter (HSI) wiring harness
Compatibility: Goodman GMPH075-4 gas furnace
Connectors: OEM factory plug and terminals
Application: Ignition circuit / control board to igniter

OEM vs. Generic

The OEM 2568416 uses high-temperature insulation rated for the burner enclosure and molded connectors that seat positively into the control board — no splicing or crimping required. Generic universal harnesses often ship as bare pigtails that force field splices, introduce added resistance, and can loosen under vibration. For a safety-critical ignition circuit, the exact-fit OEM part is the recommended choice.

Install Difficulty

Easy — most homeowners and techs can swap this harness in 15–20 minutes with basic hand tools. Cut power at the disconnect, photograph the routing, unplug the old harness at both ends, and seat the replacement. If you are not comfortable working inside a gas furnace, use a licensed HVAC technician.

Compatible with Goodman GMPH075-4 furnaces. Verify your unit's part number against 2568416 before ordering.
