On each call for heat the control board energizes this element until it glows white-hot, lighting the burners. HSIs are brittle and wear out from repeated thermal cycling — cracking or reading open-circuit — which leaves the furnace with a healthy inducer and gas valve but no flame. This exact-fit replacement restores dependable first-try ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1401018S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Hot surface ignitor (silicon carbide)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUS100-4 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 120V HSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Ignites burners on each heat cycle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman ignitor comes with the correct bracket, gasket, and plug so it seats at the exact height and angle in the burner flame path. Universal HSI kits require adapting the mount and can sit too high or low, causing slow or failed ignition and premature failure. Given how ignition-critical and fragile this component is, the OEM part is the dependable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Cut power, remove one or two mounting screws, unplug the connector, and install the new ignitor. \u003cstrong\u003eNever touch the ceramic element with bare fingers\u003c\/strong\u003e — skin oils create hot spots that cause early failure.
