ICP Direct Spark Igniter for RGS180HSAA0AAAA — OEM 1184216 | Ships Today

Overview

This is the genuine OEM spark igniter (sparker), part number 1184216, for the ICP/Tempstar/Heil RGS180HSAA0AAAA gas furnace. Unlike a hot-surface igniter, a spark igniter generates a high-voltage arc to light the burner gas on each call for heat and, in many designs, also serves as the flame-sensing electrode. When the igniter electrode cracks, the gap drifts, or the ceramic insulator fouls with carbon, the furnace will spark but fail to light, light and then lock out, or short-cycle on flame-proving faults. Replacing this inexpensive component restores reliable ignition.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS180HSAA0AAAA and related ICP-family furnaces that use direct spark ignition and specify part 1184216. Verify against your unit's parts breakdown, as electrode geometry and gap are model-specific.

Installation Guide

1. Safety First — Shut off gas and power; verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position, gap, and wire routing before removal.
4. Remove — Unplug the high-voltage lead and unscrew the old igniter from the burner bracket.
5. Install — Mount the new igniter, set it to the same position, and reconnect the lead per your photo.
6. Test — Restore gas and power, run a heat cycle, and confirm a strong spark and clean light-off.

Signs You Need a Replacement

• Furnace clicks/sparks but burner won't light
• Ignition lockout after several failed attempts
• Cracked ceramic insulator or visibly worn electrode
• Short-cycling on flame-sense faults
