ICP Hot Surface Igniter for RGX048KMCA0AAA — OEM Ignitor | Ships Today

Overview

This OEM hot surface igniter (part 1171306) for the ICP Tempstar Heil RGX048KMCA0AAA gas furnace lights the burners at the start of every heat cycle. When the control board calls for heat, the igniter receives line voltage and glows red-hot, igniting the gas as the valve opens. Hot surface igniters are one of the most common furnace failures — the brittle silicon carbide or nitride element develops hairline cracks from repeated thermal cycling and eventually breaks, leaving the furnace unable to light. A failed igniter is the typical cause of a furnace that clicks, draws, but produces no heat, often locking out after several failed ignition attempts.

Installation Guide

1. Safety First — Shut off gas and power at the furnace, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter mounting and wire routing before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the fragile element — never touch the new element with bare fingers.
5. Install — Mount the new igniter, secure the screw, and plug in the connector per your photo.
6. Test — Restore gas and power, then verify the igniter glows and the burners light cleanly.
