ICP Igniter Electrode for RGS336LEFA0AAAA — OEM 1179966 | Ships Today

Overview

This OEM igniter electrode (part number 1179966) is the ignition component for the gas heat section of the ICP/Tempstar/Heil RGS336LEFA0AAAA packaged unit. The electrode delivers the spark or hot-surface ignition needed to light the burners on a call for heat and, depending on configuration, also helps prove flame. Like all ignition components it is exposed to repeated thermal stress and eventually cracks, fouls, or loses its gap/position. Symptoms include no ignition, repeated ignition lockouts, delayed or rough light-off, or a cracked ceramic insulator. Installing the correct OEM electrode restores fast, dependable ignition each cycle.
