Overview
This OEM hot surface igniter (part 1171306) with its matching wiring kit (part 1188370) is the ignition source for the ICP Tempstar Heil RGS120LDBB0AAA gas furnace. On each heat call the control board energizes the igniter, which glows orange-hot and lights the gas at the burners. Hot surface igniters are brittle and consumable — the silicon carbide or silicon nitride element degrades with every cycle and eventually cracks, leaving the furnace with no ignition. The included wiring kit replaces the dedicated igniter harness/connector so you restore a clean, corrosion-free electrical connection at the same time. A failed igniter is the single most common cause of a furnace that ignites intermittently or not at all.

- Access — Remove the furnace burner/service panel to expose the igniter.
- Document — Photograph the igniter mounting and the wiring harness routing before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw(s); discard the cracked element and old harness.
- Install — Mount the new igniter without touching the element, install the new wiring kit, and reconnect.
- Test — Restore gas and power, start a heat call, and confirm the igniter glows and lights the burners.
Signs You Need a Replacement
- Furnace clicks/calls for heat but the burners never light.
- Visible crack, chip, or blistering on the igniter element.
