Overview

This OEM ICP igniter electrode (part number 1179966) is the ignition component responsible for lighting the burners in your ICP / Heil / Tempstar gas furnace. On each call for heat, the control board energizes the igniter so it can ignite the gas as it flows across the burners. Over time, ignition components degrade from thermal cycling, develop cracks or hairline fractures, or simply wear out — leaving you with a furnace that clicks and tries to start but never lights, or that locks out after several failed ignition attempts. Because the igniter is a wear item exposed to extreme heat on every cycle, it is one of the most common no-heat failure points in modern furnaces. Replacing it with the correct OEM electrode restores fast, dependable ignition and clears the most common cause of an intermittent or completely dead furnace.
