The genuine OEM Goodman 0130F00008S hot surface ignitor (HSI) is the exact factory replacement for the WFD195090S4CAA gas furnace. The ignitor glows red-hot on a call for heat to light the main burners. A cracked, worn, or contaminated ignitor is the single most common cause of a furnace that clicks but produces no heat — this OEM part restores reliable startup every cycle.
Universal ignitors require splicing, adapter brackets, and guesswork on resistance and voltage compatibility. The genuine 0130F00008S is a plug-and-play match with the correct connector, bracket geometry, and heat profile the furnace control board expects — reducing the risk of premature failure and repeat no-heat service calls.
Moderate (2/5). Always shut off power and gas before servicing. Remove the burner-compartment door, unplug the ignitor connector, remove the mounting screw, and swap in the new unit — handle the fragile element by the ceramic base only, never the glowing tip. Most confident DIYers complete this in 20–30 minutes; when in doubt, use a licensed HVAC technician.
Restore dependable ignition to your Goodman furnace with the genuine 0130F00008S hot surface ignitor.
