ICP Spark Igniter for RGS180LTCA0AAAA — OEM 1184216 Direct Spark Ignitor | Ships Today

Overview

This OEM spark igniter (part number 1184216) is the factory-specified ignition sparker for the ICP / Tempstar / Heil RGS180LTCA0AAAA gas furnace. A spark igniter generates the high-voltage arc that lights the burner gas at the start of every heat cycle and, on many designs, also confirms flame through the same electrode. Because it endures repeated high-voltage arcing and direct flame exposure, the electrode and ceramic insulator degrade over time — a worn igniter is a leading cause of failed ignition and no-heat lockouts.

Specifications

Compatibility

Direct OEM replacement for the ICP / Tempstar / Heil RGS180LTCA0AAAA furnace. Match the bracket shape, electrode geometry, and lead connector to your original igniter to ensure correct spark gap and flame alignment.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position, spark gap, and lead routing before disconnecting.
4. Remove — Unplug the ignition lead, remove the mounting screw(s), and lift the old igniter out of the burner assembly.
5. Install — Set the new igniter so the electrode aligns with the burner port, fasten it, and reconnect the high-voltage lead per your photo.
6. Test — Restore gas and power, call for heat, and confirm a strong spark and reliable burner light-off with no lockouts.

Signs You Need a Replacement

• Furnace clicks but won't light, or locks out on failed ignition
• Weak, intermittent, or no visible spark at the electrode
• Cracked ceramic insulator or eroded electrode tip
• Repeated ignition retries before the burner finally lights
