ICP Heil Tempstar Igniter Electrode for RGS240HDEA0AAAA — OEM Direct-Spark | Ships Today

Overview

This genuine OEM igniter electrode (part 1179966) provides the high-voltage spark that lights the burners in your ICP / Heil / Tempstar RGS240HDEA0AAAA gas furnace. On a heat call, the control board sends a spark across the electrode gap to ignite gas at the burner; the same or a paired electrode often doubles as the flame-sensing rod. A cracked ceramic insulator, eroded electrode tip, carbon buildup, or an out-of-spec gap causes failed ignition, repeated lockouts, delayed light-off, or rough flame rollout. Installing a fresh OEM electrode with the correct gap restores fast, reliable ignition every cycle.

Specifications

Compatibility

Designed for the ICP / Heil / Tempstar RGS240HDEA0AAAA and related ICP-family gas furnaces. Verify the electrode bracket, rod length, and gap against your existing part before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power; verify zero voltage with a multimeter before working near the burner.
2. Access — Remove the burner compartment door.
3. Document — Photograph the electrode position, gap, and ignition lead before removing.
4. Remove — Disconnect the high-voltage lead and unfasten the old electrode from the burner bracket.
5. Install — Mount the new OEM electrode, set the manufacturer-specified gap, and reconnect the lead.
6. Test — Restore gas and power, then confirm a clean spark and prompt burner ignition.

Signs You Need a Replacement

• Furnace locks out after several failed ignition attempts.
• Cracked or chipped ceramic insulator.
• Weak, erratic, or no visible spark at the gap.
• Delayed ignition with a noticeable gas smell or rollout.
