ICP Spark Igniter for RGS180SDCA0AAAA — OEM Sparker | Ships Today

Overview

This is a genuine OEM spark igniter / sparker (part number 1184216) for the ICP/Tempstar/Heil RGS180SDCA0AAAA gas furnace. On a spark-ignition system, the igniter generates a high-voltage spark across its electrode gap to light the burner gas at the start of every heat cycle. A clean, correctly gapped electrode is essential for fast, reliable ignition. As the electrode erodes, cracks, or fouls with carbon, the spark weakens and ignition becomes slow or fails entirely, often tripping the control board into lockout after several failed attempts. Common symptoms include no spark at startup, repeated ignition lockouts, delayed light-off with a rollout puff, and a cracked ceramic insulator.

Installation Guide

1. Safety First — Shut off gas, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, wire routing, and electrode gap before removal.
4. Remove — Disconnect the igniter lead and unscrew the igniter from the burner assembly.
5. Install — Mount the new igniter, set the specified electrode gap, and reconnect the lead.
6. Test — Restore gas and power, call for heat, and confirm a strong spark and clean burner light-off.
