Goodman 2568416 HSI Wiring Harness

The Goodman 2568416 is a genuine OEM hot surface igniter (HSI) wiring harness built as a direct replacement for the GMPH120-5 furnace. 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.

Specifications

OEM Part Number: 2568416
Part Type: HSI (Hot Surface Igniter) Wiring Harness
Brand: Goodman (Genuine OEM)
Fits Model: GMPH120-5
Features: High-temperature insulated leads, keyed plug-and-play connectors

OEM vs. Generic

The 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.

Installation Difficulty

Easy — 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. A 10–15 minute repair for most DIYers; no cutting or crimping required.
