ICP Spark Igniter for RGS180SDEA0AAAA — OEM 1184216 | Ships Today

Overview

This is the OEM spark igniter (sparker) — part number 1184216 — for the ICP Tempstar Heil RGS180SDEA0AAAA gas furnace. On a spark-ignition system, the igniter generates a high-voltage arc at the burner to light the gas at the start of each heating cycle. As the electrode erodes or the porcelain insulator cracks, the spark weakens and the furnace fails to light, short-cycles on ignition lockout, or produces no heat. Replacing a worn igniter restores fast, reliable burner ignition.

Specifications

Compatibility

Direct-fit replacement for the ICP Tempstar Heil RGS180SDEA0AAAA gas furnace. Serves matching spark-ignition burner assemblies across ICP-built Heil, Tempstar, and Comfortmaker furnaces using this design. Confirm your existing igniter matches part 1184216 before ordering.

Installation Guide

1. Safety First — Shut off gas and disconnect power. Verify zero voltage with a multimeter — the ignition circuit carries high voltage.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position, gap, and wiring before removal.
4. Remove — Disconnect the igniter lead, unfasten the mounting screw, and lift out the old sparker without touching the new electrode with bare fingers.
5. Install — Mount the new 1184216 igniter, set it at the correct spark gap, and reconnect the lead per your photo.
6. Test — Restore gas and power, call for heat, and confirm a strong spark lights the burners promptly.

Signs You Need a Replacement

• Furnace clicks but burners won't light
• Weak, intermittent, or no visible spark at the burner
