The hot surface ignitor (HSI) glows to light the burners on each heat call; it is one of the most common furnace failure points, cracking or burning out over time and leaving you with a furnace that clicks and tries to start but produces no heat. This factory part restores dependable first-attempt ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20165703S\u003c\/li\u003e\n\u003cli\u003eFunction: Hot surface ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: WFM18140S5DNCC (Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003eElement: High-temperature igniter with factory mounting bracket and connector\u003c\/li\u003e\n\u003cli\u003eType: Direct factory replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eUniversal HSI kits require adapting the bracket and splicing the connector, and their heat-up curve may not match what the WFM18140S5DNCC control board sequences for. The OEM 20165703S includes the correct bracket and plug so it seats in the original position with proper burner alignment and ignition timing — no splicing.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy — DIY friendly (2\/5).\u003c\/strong\u003e Usually one or two mounting screws and a single plug connector.
