ICP Ignitor Electrode for RGS243HSFA0AAAA — OEM Part 1179966 | Ships Today

Overview

This is the genuine OEM ignitor electrode (part number 1179966) for the ICP / Tempstar / Heil RGS243HSFA0AAAA gas/electric package unit. The ignition electrode delivers the spark that lights the burner during the heating cycle and, on many designs, also serves as the flame-sensing rod that proves a stable flame. When the electrode's tip erodes, the ceramic insulator cracks, or the gap drifts out of spec, the unit may fail to light, lock out after several trial-for-ignition attempts, or ignite then immediately shut down on a flame-proving fault. A new OEM electrode restores reliable, on-demand ignition.

Installation Guide

1. Safety First — Shut off the gas, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the electrode position, gap, and ignition lead routing.
4. Remove — Disconnect the high-voltage lead and unfasten the electrode from the burner bracket.
5. Install — Mount the new electrode, set it to the OEM gap, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then confirm clean ignition and stable flame proving.

Signs You Need a Replacement
