ICP Hot Surface Igniter Kit for RGS120HDCB0AAA — With Wiring Harness | Ships Today

Overview

This OEM hot surface igniter kit for the ICP / Tempstar / Heil RGS120HDCB0AAA includes the igniter (part number 1171306) and the matching igniter wiring kit (part number 1188370). The hot surface igniter glows red-hot when energized to ignite the gas at the burners on each heat call. Igniters are a common wear item — the brittle silicon carbide or nitride element degrades with every thermal cycle and eventually cracks or fails open. Symptoms include a furnace that won't light, an igniter that no longer glows, repeated lockouts after several failed ignition attempts, or a visibly cracked or white-spotted element. The included wiring kit ensures a clean, factory-correct electrical connection.
