This is a genuine OEM hot surface igniter (part number 606996, "IGNITOR X") for the ICP / Tempstar / Heil WUGF060AG01 gas furnace. The hot surface igniter glows red-hot on each call for heat to light the gas at the burners. It runs on 120V and is a high-wear consumable: its silicon carbide element weakens with every ignition cycle and ultimately cracks or fails open. A failed igniter means the furnace cannot light, leaving the home without heat. Watch for no flame on a heat call, the furnace locking out after several attempts, or the control board flashing an ignition-failure code. The element is brittle, so even minor mishandling or thermal shock can crack it and end its service life.
