ICP Hot Surface Igniter Electrode for RGS303LDAA0AAAA | Ships Today

Overview

This genuine OEM igniter electrode (part number 1179966) is the ignition component for the ICP/Tempstar/Heil model RGS303LDAA0AAAA gas unit. On a call for heat, the control board sends voltage to the igniter, which heats up and lights the burners so the heat exchanger can warm the supply air. Igniters are fragile and wear out from thermal cycling, cracking, or carbon contamination. Common failure symptoms include no heat, the furnace locking out after several ignition attempts, a glowing igniter that never lights the gas, or a visibly cracked element.
