This igniter serves as the initiator of the combustion cycle, generating the surface temperature required to light the gas burner on each heating call. HVAC technicians install this part during routine maintenance or when diagnosing a no-heat condition traced to igniter failure. Its universal design broadens replacement applicability across a range of residential furnace configurations.\u003c\/p\u003e\u003cp\u003eThe SIG1100 is suited for residential forced-air gas furnace applications where hot surface ignition is the standard ignition method. It is typically installed during heating-season service calls or as part of a proactive replacement when the existing igniter shows signs of cracking, incomplete lighting, or extended lockout faults. Licensed HVAC technicians performing igniter replacements will find this a practical stock item for common service scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUniversal fit design broadens compatibility across residential gas furnace models\u003c\/li\u003e\n\u003cli\u003eFunctions as a direct hot surface ignition replacement for failed or cracked igniters\u003c\/li\u003e\n\u003cli\u003eInitiates the combustion cycle on each heating call, supporting reliable furnace operation\u003c\/li\u003e\n\u003cli\u003eSuitable for use in standard residential forced-air gas furnace installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a universal OEM-style replacement hot surface igniter for residential forced-air gas furnaces using hot surface ignition systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of a furnace igniter should be performed by a licensed HVAC technician in accordance with local codes and the furnace manufacturer's service documentation. Always shut off electrical power at the disconnect or breaker and turn off the gas supply before beginning igniter removal or installation. Handle the igniter element carefully and avoid direct skin contact with the ceramic or silicon nitride tip, as oils from skin contact can cause premature failure. Confirm proper seating and wiring connection before restoring power and cycling the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential forced-air gas furnace hot surface ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type\u003c\/strong\u003e: Universal replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRANE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SIG1100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51506717688114,"sku":"SIG1100","price":39.25,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/trane-sig1100-universal-furnace-igniter","provider":"Voomi Supply","version":"1.0","type":"link"}
