Smith gas-fired water heating equipment. The kit restores proper ignition function when the original igniter has failed, cracked, or degraded past reliable operation. Hot-surface igniters are a critical component in the ignition sequence of gas appliances — when the igniter fails, the burner will not light and the unit cannot produce heat. This kit is the manufacturer-specified replacement for this ignition position and is installed by licensed plumbers, HVAC technicians, or gas appliance service professionals.\u003c\/p\u003e\n\u003cp\u003eThis igniter kit is intended for residential or light-commercial A.O. Smith gas-fired water heaters where the 100093631 is the specified replacement part. It is used in standard gas ignition system service calls where the hot-surface igniter is the diagnosed point of failure. Installers should verify the part number against the unit's service label or parts list before installation to confirm correct fitment for the specific appliance model being serviced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eManufacturer-specified hot-surface igniter replacement for compatible A.O.

Before beginning work, shut off the gas supply to the appliance and disconnect electrical power. Hot-surface igniters are fragile — handle the igniter element only by its lead wires or mounting bracket and avoid contact with the ceramic element, as skin oils can cause premature failure. Verify the replacement part number against the appliance rating plate or parts list before installing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Hot-Surface Igniter Replacement Kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Gas-Fired Water Heating Equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100093631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51149562216754,"sku":"100093631","price":85.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987705.jpg?v=1778597135","url":"https:\/\/voomisupply.com\/products\/ao-smith-100093631-igniter-replacement-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
