Built from recrystallized silicon carbide, it operates at 120 volts AC and reaches ignition temperature in approximately 17 seconds. The ignitor connects via a 5\/8 inch terminal connector and features a 4.5 inch lead wire for routing to the control board. HVAC technicians install this ignitor as a direct replacement in residential and light commercial gas furnaces where the original silicon carbide ignitor has failed or cracked. Its compact design and standard voltage rating make it a widely applicable service part.\u003c\/p\u003e\u003cp\u003eThis ignitor is suited for residential and light commercial gas furnace applications requiring a 120 volt AC hot surface ignition system. It is appropriate for systems that use silicon carbide ignitors with a 2 inch base. Technicians typically encounter this part during heating season callouts when ignitor failure prevents burner activation. The 17-second heat-up time is consistent with standard silicon carbide ignition sequences used in many forced-air furnace designs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRecrystallized silicon carbide construction for reliable high-temperature performance\u003c\/li\u003e\n\u003cli\u003e120 volt AC operating voltage matches standard residential furnace ignition circuits\u003c\/li\u003e\n\u003cli\u003e17-second ignition temperature reach time compatible with typical furnace control timing sequences\u003c\/li\u003e\n\u003cli\u003e4.5 inch lead wire length provides routing flexibility inside the heat exchanger cabinet\u003c\/li\u003e\n\u003cli\u003e5\/8 inch terminal connector for secure, vibration-resistant electrical connection\u003c\/li\u003e\n\u003cli\u003e2 inch base size for fitment in common OEM ignitor mounting configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement hot surface ignitor for gas furnaces requiring a 120 volt AC silicon carbide ignitor with a 2 inch base and 5\/8 inch terminal connector.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect power and shut off the gas supply to the appliance before removing the original ignitor. Handle silicon carbide ignitors carefully and avoid touching the ceramic element with bare hands, as skin oils can weaken the material and shorten service life. Verify that the replacement ignitor mounting orientation and lead wire routing match the original before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Recrystallized Silicon Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Temperature Reach Time\u003c\/strong\u003e: 17 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Wire Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Connector Type\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INVENSYS CLIMATE CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41-409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INVENSYS CLIMATE CONTROLS","offers":[{"title":"Default Title","offer_id":52078585643314,"sku":"41-409","price":30.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e372815f34ffa3c50c60a710b1fba9b4.jpg?v=1790054253","url":"https:\/\/voomisupply.com\/products\/invensys-climate-controls-41-409-hot-surface-ignitor","provider":"Voomi Supply","version":"1.0","type":"link"}
