ICP Hot Surface Igniter for RGS120LTAA0AGAA – With Wiring Kit | Ships Today

Overview

This genuine OEM hot surface igniter (part #1171306) ignites the burners on your ICP, Tempstar, and Heil gas furnace, and this kit includes the matching igniter wiring harness (part #1188370) for a complete, plug-and-play repair. When the control board calls for heat, the igniter glows white-hot and lights the gas at the first burner. Hot surface igniters are fragile silicon-nitride or silicon-carbide elements that degrade with every heating cycle and eventually crack, leaving you with no heat, repeated ignition lockouts, or a furnace that cycles the inducer and gas valve but never lights. Including the fresh wiring kit eliminates the brittle, heat-damaged connector that is a frequent hidden cause of igniter failure.
