Overview

This OEM hot surface igniter (part 1171306) is the ignition source for your ICP/Heil/Tempstar RGS121SEBB0AAAA gas furnace. When the thermostat calls for heat, the control board sends voltage to the igniter, which glows red-hot to ignite the gas at the burners. This kit also includes the matching igniter wiring kit (part 1188370) so you replace the harness and connector at the same time, eliminating a common second point of failure. A cracked or worn igniter is one of the most frequent causes of no-heat calls.
