ICP Spark Igniter for RGS180LFCA0AAAA — Direct-Spark Ignitor | Ships Today

Overview

This OEM spark igniter (part #1184216) generates the high-voltage arc that lights the burners on your ICP/Tempstar/Heil RGS180LFCA0AAAA gas furnace. On a heat call, the control board sends voltage to the igniter electrode, producing a spark across the gap to ignite the gas at the pilot or primary burner. A worn, cracked, or carbon-fouled igniter is one of the most common causes of furnace no-heat and short-cycling complaints. Symptoms include audible repeated sparking with no flame, intermittent ignition lockouts, or a furnace that runs the inducer and gas valve but never lights.

Specifications

Compatibility

Direct-fit for the ICP/Tempstar/Heil RGS180LFCA0AAAA and related Comfortmaker, Arcoaire, and KeepRite furnaces using the same spark-ignition burner assembly. Confirm the electrode bracket and gap orientation match your existing igniter.

Installation Guide

1. Safety First — Shut off gas and disconnect electrical power; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the igniter wire routing and electrode position before removing.
4. Remove — Disconnect the high-voltage lead and unscrew the igniter bracket from the burner assembly.
5. Install — Mount the new igniter, maintain the factory spark gap, and reconnect the lead per your photo.
6. Test — Restore gas and power, then confirm a strong spark and clean burner light-off on a heat call.

Signs You Need a Replacement

• Furnace sparks repeatedly but never ignites
• Intermittent no-heat calls and ignition lockouts
• Cracked ceramic insulator or carbon buildup on the electrode
• Bent or eroded electrode tip with an incorrect spark gap
