The Goodman B1401012 Hot Surface Igniter is a genuine OEM ignition component for the Goodman GMP050-3 gas furnace. The hot surface igniter (HSI) glows red-hot on a call for heat to light the burners, making it one of the most frequently replaced wear parts in any gas furnace. A cracked, worn, or open igniter is the #1 cause of a furnace that clicks but won't fire — replacing it typically restores heat immediately.
The genuine Goodman igniter is matched to the furnace's ignition timing and voltage profile, delivering consistent light-off and long service life. Universal generic igniters may need bracket adapters and can be more fragile, risking repeat failures mid-season. For reliable winter heat, OEM is the smart buy.
Easy. Shut off power and gas, unplug the igniter connector, remove one or two mounting screws, and install the replacement — handling only by the ceramic base, never the fragile element. Most homeowners can complete this in under 20 minutes; when in doubt, call a technician.
