ICP Spark Igniter for RGS180SSEA0AAAA — Direct Spark Ignition | Ships Today

Overview

This genuine OEM spark igniter (part number 1184216) is the ignition electrode for the ICP / Tempstar / Heil RGS180SSEA0AAAA gas furnace. The igniter generates the high-voltage spark that lights the pilot or burner gas at the start of each heat cycle. Over time the electrode tip erodes, the porcelain insulator cracks, or the spark gap drifts out of spec, leaving the furnace unable to light. A worn igniter is one of the most frequent causes of furnace lockout and intermittent no-heat calls during the heating season.

Specifications

Compatibility

Designed as a direct OEM replacement for the ICP / Tempstar / Heil model RGS180SSEA0AAAA. The same igniter assembly is used across many matched Comfortmaker, Arcoaire, and KeepRite furnaces built on the shared ICP platform. Verify the electrode shape and mounting bracket against your existing part before installing.

Installation Guide

1. Safety First — Shut off gas and electrical power; verify zero voltage with a multimeter before working near the burner assembly.
2. Access — Remove the furnace burner compartment door.
3. Document — Photograph the igniter position, gap, and wire routing before disconnecting.
4. Remove — Disconnect the ignition lead and unscrew the old igniter from the burner bracket.
5. Install — Mount the new igniter, set it to the factory spark gap, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then watch a full ignition cycle to confirm a strong, consistent spark and clean light-off.

Signs You Need a Replacement

• Furnace clicks but the burners fail to light
• Weak, intermittent, or no visible spark
• Cracked porcelain insulator or eroded electrode tip
