Description
Product Summary
The Supco IG401 Furnace Igniter - Exact Replacement is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Direct replacement silicon carbide igniter.
Hot surface igniters and flame sensors are the heart of modern gas furnace ignition. A cracked or weak igniter causes no-heat calls and lockouts, while a dirty or failing flame sensor causes the burners to shut down seconds after lighting. Match the igniter material (silicon carbide or silicon nitride), voltage, and mounting style to the original.
