Overview
This OEM hot surface igniter kit pairs the igniter element (part 1171306) with its matching igniter wiring harness/kit (part 1188370) for ICP Tempstar/Heil gas furnaces. On each call for heat, the furnace control sends voltage to the igniter, which glows white-hot and lights the gas at the burners. The igniter is one of the most failure-prone components in a furnace because the brittle element is heat-cycled hundreds of times per season and is easily cracked by handling or contamination. Including the wiring harness ensures a clean, corrosion-free connection from the control board to the igniter — a frequent secondary failure point. Replacing both together restores reliable, fast ignition and eliminates the no-heat, repeated-retry, and lockout symptoms caused by a cracked element or a chafed, melted harness.

Compatibility
Fits ICP, Tempstar, Heil, and Comfortmaker gas furnaces including model RGS121STAB0AAAA. Confirm the igniter mounting tab and connector style against your existing part before installing. Handle the new element by the ceramic base only — never touch the silicon-carbide tip.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position, mounting tab, and harness routing before removal.
- Remove — Unplug the harness, remove the igniter mounting screw, and carefully withdraw the cracked element.
- Install — Mount the new igniter (handling by the base only), route and connect the new wiring harness per your photo.
- Test — Restore power and confirm the igniter glows and lights the burners promptly on a heat call.
Signs You Need a Replacement
- No heat — burners never ignite on a call
- Igniter does not glow, or glows weakly
- Repeated ignition retries followed by lockout
- Visible crack in the element or melted/chafed harness
