Overview

This OEM hot surface igniter (part #1171306) is the ignition source for the ICP/Tempstar/Heil RGS121SEAA0AAAA gas furnace. When the thermostat calls for heat, the control board energizes the igniter to roughly 1,800–2,500°F so it can light the burner gas. The silicon carbide element is brittle and degrades with every heating cycle, making it one of the most common no-heat failure points. This listing ships with the matching OEM wiring kit (part #1188370) so the connector and harness are replaced together. Typical symptoms of a failed igniter include a furnace that cycles but never lights, a glowing element that cracks or no longer glows, and a unit that locks out after several ignition attempts.
