Overview
This is the OEM hot surface igniter and flame-sensor kit (OEM #1009524, "IGNITOR/SENSOR HSP SK") for the Tempstar T9MPD075F12A3 gas furnace. The hot surface igniter (HSI) is a silicon-nitride element that electrically heats to roughly 2,000°F at the start of every heat cycle, lighting the gas at the burner. The matching flame sensor confirms ignition so the control board can keep the gas valve open. A failed igniter is one of the most common no-heat causes: the element cracks from thermal cycling or contamination, the furnace tries to light, fails, and locks out. Operating on the standard 120V igniter circuit, this silicon-nitride unit is more durable than older silicon-carbide "glow bar" igniters and resists the chipping that ends most igniter service lives.

Compatibility
Engineered for the Tempstar T9MPD075F12A3 furnace and shared across the ICP family (Tempstar, Heil, Comfortmaker, and related ICP-built gas furnaces) that use the 1009524 igniter/sensor platform. Always confirm against your unit's parts list before ordering.
Installation Guide
- Safety First — Switch off the furnace at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter bracket, ceramic block, and wire routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw(s), and lift the old igniter out of the burner box. Handle by the ceramic base only — never touch the element.
- Install — Seat the new igniter so the element sits in the burner flame path, fasten the bracket, and reconnect the plug per your photo.
- Test — Restore power and run a heat cycle; confirm the igniter glows, the burners light, and the flame sensor proves the flame without lockout.
Signs You Need a Replacement
- Furnace clicks and calls for heat but burners never light.
- Igniter shows no glow, or has visible cracks/white spots on the element.
- Furnace short-cycles or locks out after 3 ignition attempts.
- Intermittent no-heat on cold mornings as the element degrades.
