ICP Spark Igniter for RGS180SFCA0AAAA – OEM 1184216 | Ships Today

Overview

This is the genuine OEM spark igniter / sparker electrode (part number 1184216) for the ICP / Tempstar / Heil RGS180SFCA0AAAA gas furnace. The spark igniter generates the high-voltage arc that lights the burner gas on each heat call. A cracked ceramic insulator, eroded electrode tip, carbon buildup, or an incorrect spark gap leads to delayed ignition, repeated ignition lockouts, no heat, or a furnace that clicks but never lights. Replacing a worn igniter with the exact factory electrode restores fast, reliable burner ignition and proper spark gap geometry.

Specifications

Compatibility

Engineered for the ICP RGS180SFCA0AAAA and shared across spark-ignition ICP-family gas furnaces carrying the Tempstar, Heil, Comfortmaker, and Arcoaire brands. Match the mounting bracket, electrode shape, and spark gap to your existing igniter before installing.

Installation Guide

1. Safety First – Shut off the gas supply, disconnect electrical power at the furnace switch and breaker, and verify zero voltage with a multimeter.
2. Access – Remove the furnace burner-compartment service panel.
3. Document – Photograph the igniter position, spark gap, and lead routing before disconnecting.
4. Remove – Disconnect the high-voltage ignition lead and unscrew the old igniter from the burner assembly.
5. Install – Mount the new 1184216 igniter, confirm the spark gap matches spec, and reconnect the ignition lead per your photos.
6. Test – Restore gas and power, start a heat call, and verify the burner lights promptly with a strong, consistent spark.

Signs You Need a Replacement

• Furnace clicks or sparks but the burner will not light
• Repeated ignition lockouts or no-heat conditions
• Cracked ceramic insulator or eroded electrode tip
