ICP Spark Igniter for RGS180HDCA0AAAA — OEM 1184216 | Ships Today

Overview

This OEM spark igniter (part number 1184216, "IGNITOR SPARKER") is the factory ignition component for the ICP / Heil / Tempstar RGS180HDCA0AAAA gas furnace. On spark-ignition systems the igniter generates a high-voltage arc at the burner to light the main gas flame on each call for heat. A worn or cracked igniter produces weak or missing sparks, leading to delayed ignition, repeated lockouts, or no heat at all. Because it is the exact OEM part, it matches the original electrode gap, mounting position, and ceramic insulator, so the burner lights reliably without field modification.

Compatibility

Designed as the factory ignition component for the ICP / Heil / Tempstar RGS180HDCA0AAAA furnace and other International Comfort Products gas furnaces sharing this ignition assembly. Always confirm part number 1184216 against your unit's parts list before ordering.

Installation Guide

1. Safety First — Disconnect electrical power and shut off the gas supply. Verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the igniter wiring and bracket position before disconnecting.
4. Remove — Unplug the igniter lead and remove the mounting screw(s); withdraw the old igniter from the burner without bending the electrode.
5. Install — Mount the new 1184216 igniter, set it to the original gap/position, and reconnect the lead per your photo.
6. Test — Restore gas and power, then watch a full ignition cycle to confirm a strong, consistent spark and burner light-off.

Signs You Need a Replacement

• Furnace clicks/sparks but the burner fails to light
• Delayed ignition or a "whoosh" of delayed flame
• Weak, intermittent, or no visible spark at the electrode
• Repeated ignition lockouts on the control board
