Overview
This is a genuine OEM hot surface igniter (part number 606996, "IGNITOR X") for the ICP / Tempstar / Heil WUGF055AD01 gas furnace. The hot surface igniter glows red-hot on every call for heat to ignite the gas at the burners. It operates on 120V and is a high-wear consumable — the silicon carbide element degrades with each ignition cycle and eventually cracks or fails open. When it fails, the furnace cannot light and the home loses heat. Common symptoms include no flame on a heat call, the furnace locking out after multiple attempts, or the control board flashing an ignition-failure fault code. Because the element is fragile, even a small crack from rough handling or thermal shock can take it out of service.

Compatibility
Directly fits the ICP / Tempstar / Heil WUGF055AD01 upflow gas furnace and many other ICP-family furnaces that use the 606996 igniter. Confirm your existing igniter part number and bracket/plug style before installing.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the igniter wiring and bracket position before disconnecting.
- Remove — Unplug the igniter harness connector and remove the mounting screw(s). Handle by the ceramic base only — never touch the gray element.
- Install — Mount the new igniter so the element sits in the burner flame path, reattach the screw(s), and reconnect the plug per your photo.
- Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light cleanly.
Signs You Need a Replacement
- Furnace will not ignite or produces no flame on a call for heat.
- Visible crack, blistering, or white powder on the igniter element.
- Igniter no longer glows red during the ignition sequence.
