Get reliable, first-try ignition with the genuine OEM Goodman 20261709S Hot Surface Ignitor (HSI). This factory ignition element is engineered for the Goodman GMP100-5 gas furnace and compatible Goodman/Amana models. When the thermostat calls for heat, the control board energizes the ignitor, which glows to light the burner gas — a worn or cracked ignitor is the single most common cause of no-heat furnace failures.

Type: Hot surface ignitor (silicon-carbide element)

Genuine OEM Goodman replacement

OEM vs. Generic

OEM ignitors match the exact resistance, glow temperature, and mounting geometry your control board expects, delivering consistent ignition and long service life. Generic ignitors may draw incorrect current or sit at the wrong burner clearance, causing delayed ignition, short cycling, or premature failure. For dependable winter heat, OEM is strongly recommended.

Installation Difficulty

Easy to Moderate. Replacement takes about 20–30 minutes with basic tools. Disconnect power first and handle the ignitor by the ceramic base only — the silicon-carbide element is extremely fragile and skin oils can shorten its life. Unplug the connector, remove the mounting screw, install the new unit, and restore power. If unsure, call a licensed HVAC technician.
