Overview

This OEM igniter electrode (Part No. 1179966) is responsible for initiating combustion in your ICP RGS243SSFA0AAAA gas furnace. On each heat call the control board energizes the igniter, which produces the high-temperature ignition source needed to light the burner gas. Because the electrode is cycled through extreme heat on every call, it is a normal wear part that eventually cracks, erodes, or fails. A failed igniter is one of the most frequent causes of no-heat conditions: you'll hear the inducer and gas valve cycle, but the burners never light, often ending in a hard lockout after several failed attempts.
