ICP Spark Igniter for RGS180SSAA0AAAA — OEM Part 1184216 | Ships Today

Overview

This is the OEM spark igniter (part number 1184216) for the ICP/Heil/Tempstar RGS180SSAA0AAAA gas furnace. On spark-ignition systems, this electrode generates the high-voltage arc that lights the burner gas at the start of each heat cycle and, on many designs, also serves as the sense rod that proves flame. A worn, cracked, or carbon-fouled igniter produces a weak or missing spark, leading to ignition lockout, delayed ignition with a rumble, or short-cycling on a failed flame-proving signal. This direct-fit OEM electrode restores reliable light-off with the correct gap and mounting geometry.

Specifications

Compatibility

Engineered for the ICP RGS180SSAA0AAAA furnace and shared across many Heil, Tempstar, and Comfortmaker spark-ignition gas furnaces using the same burner assembly. Verify your furnace uses a spark igniter (not a hot surface igniter) before ordering.

Installation Guide

1. Safety First — Shut off gas and disconnect power. Verify zero voltage with a multimeter.
2. Access — Remove the burner compartment door.
3. Document — Photograph the igniter position, gap, and ignition lead routing.
4. Remove — Disconnect the high-voltage ignition lead and unscrew the igniter from the burner bracket.
5. Install — Mount the new igniter, confirm the spark gap and electrode position over the burner, and reconnect the lead.
6. Test — Restore gas and power and verify a strong spark and clean burner light-off.

Signs You Need a Replacement

• Weak, intermittent, or absent spark at the burner
• Cracked ceramic insulator or carbon buildup on the electrode
• Furnace locks out after several failed ignition attempts
• Delayed ignition with a noticeable rumble or flame roll
