Overview
This OEM hot surface igniter (part number 1009524, IGNITOR/SENSOR HSP SK) is the ignition component for your ICP Tempstar Heil VNK050F12B2 gas furnace. When the thermostat calls for heat, the control board powers this igniter, which glows red-hot to light the burner gas. Its silicon-nitride construction withstands thousands of rapid heat-up cycles and resists the cracking and warping that ends the life of older silicon-carbide igniters. A failed igniter means no heat: the furnace cycles but the burners never light. Telltale signs include an inducer that runs and clicks with no flame, repeated ignition lockouts, or a visibly cracked, blistered, or broken igniter element.

Compatibility
Designed as a direct OEM replacement for the ICP Tempstar Heil VNK050F12B2 furnace. ICP-family equipment (Tempstar, Heil, and Comfortmaker) frequently shares this igniter across similar 50,000 BTU input gas furnaces. Always verify your existing part number before ordering.
Installation Guide
- Safety First — Shut off gas and disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter before touching any component.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the igniter bracket position and wire routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw(s), and lift out the old igniter without touching the new element with bare hands.
- Install — Mount the new igniter in the exact bracket position, reconnect the plug, and confirm the element sits in the burner flame path.
- Test — Restore gas and power, run a heat cycle, and verify the igniter glows and the burners light promptly.
Signs You Need a Replacement
- Furnace runs the inducer and clicks but never lights the burners.
- Repeated ignition lockouts after failed attempts.
- Visible cracks, blisters, or breaks in the igniter element.
