ICP Hot Surface Igniter for VNE125J20G1 — 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 VNE125J20G1 gas furnace. When the thermostat calls for heat, the control board energizes this 120V igniter, which glows red-hot to light the burner gas. This silicon nitride element doubles as a flame-sensing surface in the HSP (hot surface proven) system. A cracked, weakened, or contaminated igniter is one of the most common causes of furnace no-heat calls — the part fails to reach ignition temperature or no longer proves flame, sending the furnace into lockout.

Specifications

Compatibility

Engineered for the ICP Tempstar Heil VNE125J20G1 furnace and shared across many ICP-family (Comfortmaker, Arcoaire, KeepRite) 90%+ AFUE models that use 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 fragile element.
5. Install — Mount the new igniter so the element sits 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 clicks and tries to start but never lights
• Igniter glows dimly, 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
