Overview

Genuine OEM hot surface igniter (part #1171306) with matching igniter wiring kit (part #1188370) for the ICP / Heil / Tempstar RGS121HRBB0AAAA gas furnace. The hot surface igniter glows red-hot when energized to ignite the burner gas at the start of each heating cycle. The included wiring kit provides the correct harness and connector to ensure a clean, reliable electrical connection. Hot surface igniters are brittle and degrade over time — a cracked or worn element is one of the most common reasons a furnace blows cold air or fails to light on a call for heat.
