ICP Spark Igniter for RGS180LRAA0AAAA — Direct Spark Ignitor | Ships Today

Overview

This is a genuine ICP OEM spark igniter (sparker), part number 1184216, for the RGS180LRAA0AAAA packaged gas/electric unit. On a heat call, the ignition control sends high voltage to this electrode, generating a spark across its gap to light the gas at the burner. Unlike a hot surface igniter, a spark igniter does not glow — it arcs. As the electrode erodes or the porcelain insulator cracks, the spark weakens or shorts to ground, producing failed ignition, repeated lockouts, delayed light-off with a 'whoomp,' or no spark at all. This direct OEM replacement matches the original electrode geometry and gap so it lights the burner reliably without adjustment.

Specifications

Compatibility

Fits the ICP/Tempstar/Heil RGS180LRAA0AAAA and related RGS-series gas units that call out part 1184216. Confirm your unit uses direct spark ignition (not a hot surface igniter) and match the electrode/bracket profile before ordering.

Installation Guide

1. Safety First — Shut off the gas, disconnect power, and verify zero voltage with a multimeter. The igniter carries high voltage in operation.
2. Access — Remove the burner access panel.
3. Document — Photograph the igniter position, gap, and lead routing before removal.
4. Remove — Disconnect the ignition lead and unscrew the old igniter from the burner assembly.
5. Install — Mount the new igniter, set it in the factory position, and reconnect the lead per your photo. Avoid touching the ceramic with bare hands.
6. Test — Restore gas and power, call for heat, and confirm a strong spark and prompt burner light-off.

Signs You Need a Replacement

• No spark or weak/intermittent spark on a heat call
• Repeated ignition lockouts or failed light-off
• Delayed ignition with a rollout 'whoomp'
• Cracked porcelain insulator or eroded electrode tip
