Overview

The TRANE IG402K is a universal 120-volt silicon carbide hot surface igniter designed to replace faulty igniters in gas furnaces and heating equipment. Silicon carbide elements heat rapidly to ignition temperature, providing reliable light-off cycles season after season. The 1.25-inch ceramic base provides a stable, heat-resistant mounting point that withstands the thermal cycling demands of residential and light commercial furnace applications. This igniter is installed by licensed HVAC technicians as part of routine ignition system repairs or planned maintenance. This universal hot surface igniter is suited for residential and light commercial gas furnace applications where a 120-volt silicon carbide igniter is required. Its universal design accommodates a wide range of furnace configurations. The ceramic base mounting makes it compatible with many standard igniter mounting brackets found in gas furnace heat compartments. Always verify voltage requirements and base dimensions against the original igniter before installation.
