This ignitor glows red-hot when energized by the control board and lights the burners at the start of each heating cycle. A cracked or worn HSI is the single most common cause of a no-heat call: the inducer runs, the gas valve tries to open, but the burners never light and the furnace locks out. Swapping this part restores dependable ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20165703S\u003c\/li\u003e\n\u003cli\u003eType: Hot surface ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 120V line-voltage ignitor\u003c\/li\u003e\n\u003cli\u003eElement: High-durability ignitor material with ceramic base and mounting bracket\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman\/Amana WFD18070S3AXCC and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eUniversal ignitor kits require adapting the bracket and splicing the harness, and their resistance can differ from spec — which shortens life and risks failed ignition. This OEM 20165703S arrives with the correct bracket and connector for the WFD18070S3AXCC, so it plugs in directly and matches the board's ignition timing. The brittle silicon-carbide element is also easily cracked by rough handling; buying the exact factory part avoids install-time breakage.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eAbout 20–30 minutes. Cut power, unplug the two-pin connector, remove the mounting screw, and lift out the old ignitor. Handle the new element by the ceramic base only — never touch the glowing element with bare fingers. Seat it at the correct depth in the burner, reconnect, and test a full ignition cycle.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058216059251,"sku":"GOODMAN-13854","price":47.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-hot-surface-ignitor-for-wfd18070s3axcc-20165703s","provider":"National HVAC Parts","version":"1.0","type":"link"}
