The Goodman B1401012 Hot Surface Igniter is a genuine OEM ignition component for the GDS81155CNA gas furnace and compatible Goodman/Amana models. On each heat call, the furnace board energizes this igniter, which glows red-hot to light the main burners. A cracked, worn, or open igniter is one of the most common causes of "no heat" — the blower and inducer run, but the burners never ignite. Replacing it restores dependable, on-demand heating.
The genuine OEM Goodman igniter matches the exact resistance, glow temperature, and bracket geometry of the original, ensuring proper alignment over the burner and full compatibility with the furnace control board. Silicon-carbide igniters are fragile — cheaper generics often use inconsistent element density that shortens service life and can cause hard starts.
Rated Easy–Moderate (2/5). Shut off power and gas, unplug the igniter connector, remove the mounting screw, and swap in the new unit. Never touch the igniter element with bare fingers — skin oils create hot spots that cause premature failure. Handle by the ceramic base only. A 15–20 minute repair for most DIYers.
