Overview
This OEM hot surface igniter/sensor service kit (part #1009524) provides reliable ignition for the Tempstar T9MPV100J20B1 gas furnace. On each heating call the integrated control board energizes the igniter, which heats to a glowing temperature and ignites the gas at the burners; the kit's sensor element then confirms flame so the gas valve stays open. A failed igniter is one of the most common causes of no-heat calls: the element develops hairline cracks or simply burns out from thermal cycling, and the furnace locks out after several failed ignition attempts. Hot surface igniters are fragile silicon-nitride or silicon-carbide elements that should be handled only by the ceramic base — never touch the element itself, as skin oils shorten its life. Installing this OEM kit restores dependable lighting and proper flame sensing.

Compatibility
Designed as a direct-fit replacement for the Tempstar T9MPV100J20B1 modulating variable-speed gas furnace. This igniter/sensor kit is shared across many ICP-family furnaces (Tempstar, Heil, Comfortmaker, Arcoaire) using the same ignition system. Match the mounting bracket and connector to your existing igniter before installing.
Installation Guide
- Safety First — Shut off gas and disconnect power at the switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner/control compartment service panel.
- Document — Photograph the igniter bracket position and wiring connector before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw; lift the old igniter out by its ceramic base.
- Install — Set the new igniter handling only the ceramic base, secure the bracket screw, and reconnect the plug per your photo.
- Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and the burners light and stay lit.
Signs You Need a Replacement
- Furnace blower runs but burners never ignite (no heat).
- Igniter does not glow during the ignition sequence.
- Furnace locks out after 3 ignition attempts and the LED flashes an ignition fault.
