ICP Spark Igniter for RGS180STEA0AAAA — OEM 1184216 | Ships Today

Overview

This is the genuine OEM spark igniter (part number 1184216) for the ICP / Tempstar / Heil RGS180STEA0AAAA gas furnace. The spark igniter generates the high-voltage arc that lights the burner gas at the start of each heating cycle. Unlike a hot-surface igniter, a spark igniter ignites the flame directly through an electrode gap and is paired with the furnace's ignition control. A cracked ceramic insulator, eroded electrode, or fouled tip will cause weak or missing spark, resulting in failed ignition, lockouts, or no heat. The factory part guarantees the correct electrode geometry and gap for reliable light-off.

Specifications

Compatibility

Direct-fit replacement spark igniter for the ICP/Tempstar/Heil RGS180STEA0AAAA gas furnace. Confirm your model number and that your furnace uses a spark (not hot-surface) ignition system before ordering.

Installation Guide

1. Safety First — Shut off the gas and disconnect power. Verify zero voltage with a multimeter; the spark circuit carries high voltage.
2. Access — Remove the furnace burner/service panel to reach the igniter at the burner assembly.
3. Document — Photograph the igniter position, gap, and the high-voltage lead routing before removing.
4. Remove — Disconnect the ignition lead, unfasten the mounting screw, and carefully withdraw the old igniter without touching the ceramic.
5. Install — Mount the new igniter at the correct position/gap and reconnect the high-voltage lead per your photos.
6. Test — Restore gas and power, start a heat cycle, and confirm a strong spark and clean burner ignition.

Signs You Need a Replacement

• Furnace fails to ignite or goes into ignition lockout
• Weak, intermittent, or no visible spark at the burner
• Cracked ceramic insulator or eroded/corroded electrode
• Repeated retries before the burner finally lights
