Overview

This OEM kit pairs the hot surface igniter (part 1171306) with its matching igniter wiring kit (part 1188370) for the ICP Tempstar Heil RGS120HSCA0AAA gas furnace. The hot surface igniter is the ceramic element that glows red-hot when energized to ignite the burner gas at the start of every heat cycle, and the included wiring kit provides the correct OEM harness and connector for a clean, reliable connection. Hot surface igniters are fragile and wear out — the element develops microscopic cracks and eventually fails to reach ignition temperature, leaving you with no heat. A cracked or corroded igniter plug can cause the same intermittent no-heat symptoms. Replacing both the igniter and its harness together restores dependable ignition and prevents repeat callbacks.
