Overview

This OEM hot surface igniter heats to glowing temperature to light the gas burners on the heating side of your ICP WPG4244040RKB1 packaged unit. The ignition control board energizes the igniter at the start of each heat cycle; the element glows, the gas valve opens, and the burners light. Hot surface igniters are brittle and have a finite life — they crack, develop hairline fractures, or simply burn out, which is one of the most common no-heat failures. If the igniter glows but the burners never light, glows weakly, or shows no glow at all on a heat call, replacement is the fix. This listing covers the ignitor (1177663) and its control board igniter assembly (1186861). Never touch the element with bare fingers; skin oils shorten its life.
