When your furnace clicks but fails to light, a cracked or worn ignitor is the most common cause. This factory-spec part restores reliable, on-demand ignition and eliminates the no-heat call.\u003c\/p\u003e\u003cp\u003eBuilt to Goodman's exact resistance and dimensional specifications, the 20165703S drops into the original mounting bracket with no modification. The silicon nitride element heats to ignition temperature in seconds and resists the thermal cycling and micro-cracking that shortens the life of cheaper universal igniters.\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 (silicon nitride)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana WFM18090S4BXCB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eVoltage: 120V ignition circuit\u003c\/li\u003e\n\u003cli\u003eDirect OEM-fit mounting bracket and connector\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGeneric hot surface ignitors often use brittle silicon carbide elements and loose-tolerance brackets that force you to re-bend tabs or splice connectors.
