ICP Ignitor Electrode for RGS240HDFA0AAAA — Direct Spark Ignition | Ships Today

Overview

This OEM ignitor electrode (part number 1179966 — IGNITOR ELECTRODE) delivers the high-voltage spark that lights the gas burner on your ICP / Tempstar / Heil RGS240HDFA0AAAA rooftop gas-electric package unit. On each heat call, the control board energizes the electrode, producing a spark across the gap to ignite the burner gas. The same electrode assembly typically doubles as part of the flame-proving circuit, confirming the burner has lit. When the electrode cracks, fouls with carbon, or the gap drifts out of spec, the unit fails to ignite — or lights and then locks out on a failed flame signal. Common symptoms include no ignition on a heat call, repeated ignition-lockout codes, delayed or rough light-off, and short cycling on the burner.

Compatibility

Direct OEM replacement for the ICP / Tempstar / Heil RGS240HDFA0AAAA rooftop gas-electric package unit. Verify part number 1179966 and the electrode bracket geometry against your existing part before ordering.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage at the unit.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the electrode position, wire routing, and spark-gap orientation before removal.
4. Remove — Disconnect the high-voltage ignition lead and ground, then unscrew the electrode from the burner bracket.
5. Install — Mount the new electrode, set the spark gap per the unit spec, and reconnect the ignition lead.
6. Test — Restore gas and power, call for heat, and confirm clean spark, ignition, and stable flame.

Signs You Need a Replacement

• No spark or no ignition on a heat call
• Repeated ignition-lockout fault codes
• Cracked ceramic insulator or carbon-fouled tip
• Burner short-cycles or fails to prove flame
