ICP Hot Surface Igniter for VNE100J20G1 — 120V Silicon Nitride | Ships Today

Overview

The OEM hot surface igniter (part 1009524, IGNITOR/SENSOR HSP SK) is the ignition source for your ICP Tempstar Heil VNE100J20G1 gas furnace. On a heat call the control board energizes this 120V silicon nitride element until it glows hot enough to light the burner gas, and the same surface proves flame in the HSP (hot surface proven) ignition system. The element is fragile and endures constant thermal cycling, making it one of the most common no-heat failure points — once it cracks or weakens, the furnace fails to ignite or goes into lockout.

Specifications

Compatibility

Engineered for the ICP Tempstar Heil VNE100J20G1 furnace and shared across many ICP-family (Comfortmaker, Arcoaire, KeepRite) 90%+ AFUE furnaces on the HSP ignition platform. Always confirm against your unit's parts list before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas. Verify zero voltage with a multimeter.
2. Access — Remove the lower service panel to expose the burner assembly.
3. Document — Photograph the igniter bracket and wire routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw(s). Handle only by the ceramic base — never touch the element.
5. Install — Mount the new igniter with the element in the burner flame path, reconnect the plug, and reinstall the screw.
6. Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light and stay lit.

Signs You Need a Replacement

• Furnace tries to start but the burners never light
• Igniter glows weakly, unevenly, or not at all
• Visible cracks, hairline fractures, or white/gray buildup on the element
• Repeated ignition lockouts or short cycling on a heat call
