The silicon nitride element operates at 120 volts and provides reliable ignition across a wide range of OEM furnace configurations. The kit ships with five mounting brackets and all necessary hardware, allowing the technician to match the correct bracket to the existing furnace mount without sourcing additional hardware. HVAC service technicians install this igniter as a direct replacement when the original igniter has cracked, failed open, or is drawing out-of-spec resistance. The 9-inch lead length accommodates most standard furnace wiring harnesses.\u003c\/p\u003e\n\u003cp\u003eThis igniter kit is suited for residential gas furnaces and fan-assisted combustion systems where a flat silicon nitride element is specified. The five included brackets simplify installation in tight heat exchanger compartments and cover the mounting hole patterns used across numerous OEM models. It is intended for service and repair work performed by licensed HVAC technicians familiar with gas furnace ignition systems. The kit replaces the following OEM part numbers: 41-402, 41-403, 41-404, 41-405, 41-407, 41-408, 41-409, 41-410, 41-412, 41-414, 41-1090, 41-238, and 41.242.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon nitride element resists vibration and thermal cycling that can crack fragile silicon carbide igniters\u003c\/li\u003e\n  \u003cli\u003eOperates at 120 volts to match standard residential furnace ignition circuits\u003c\/li\u003e\n  \u003cli\u003eFive mounting brackets included to cover multiple OEM hole patterns in a single kit\u003c\/li\u003e\n  \u003cli\u003e9-inch lead length fits most standard furnace wiring harnesses without splicing\u003c\/li\u003e\n  \u003cli\u003eReplaces 13 OEM part numbers, reducing the number of SKUs a technician needs to stock on a service van\u003c\/li\u003e\n  \u003cli\u003eMounting hardware included  -  no separate trip to source fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eReplaces OEM part numbers 41-402, 41-403, 41-404, 41-405, 41-407, 41-408, 41-409, 41-410, 41-412, 41-414, 41-1090, 41-238, and 41.242.

Shut off power to the furnace at the disconnect and close the manual gas shutoff valve before removing the failed igniter. Silicon nitride elements are more durable than silicon carbide but should still be handled without touching the element surface, as skin oils can create hot spots that reduce service life. Confirm the selected bracket aligns with the furnace mounting holes before final tightening, and verify 120-volt supply to the igniter circuit before returning the furnace to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElement Material\u003c\/strong\u003e: Silicon Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgniter Type\u003c\/strong\u003e: Flat Hot Surface Igniter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 5 Mounting Brackets and Hardware\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\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: DIVERSITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IG4000N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":68632795152690,"sku":"IG4000N","price":71.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77980be8db969f7f06d37187e0bc85dd.jpg?v=1794361352","url":"https:\/\/voomisupply.com\/products\/diversitech-ig4000n-universal-silicon-nitride-igniter-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
