Overview
This OEM hot surface igniter/sensor (part #1009524) lights the burners on your Tempstar TNE100J20A1 furnace. On each call for heat the control board energizes the igniter, which glows hot to ignite the gas at the burners; the same silicon nitride element family also provides robust, durable starts compared to older silicon carbide igniters. A cracked or worn igniter is the leading cause of no-heat calls: the inducer runs and the gas valve tries to open, but the burners never light and the furnace locks out. Hairline cracks, a no-glow condition, or repeated ignition lockouts all point to a failed igniter.

Compatibility
Engineered as the exact OEM replacement igniter for the Tempstar TNE100J20A1 furnace. This hot surface igniter is shared across many ICP-family gas furnaces (Tempstar, Heil, Comfortmaker, Arcoaire) using the same burner and ignition platform. Verify your existing igniter's mounting bracket and connector match before installing.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner compartment service panel.
- Document — Photograph the igniter position and wiring connector before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the new igniter by the bracket only — never touch the ceramic element.
- Install — Mount the new igniter so it aligns over the burner, then reconnect the wiring per your photo.
- Test — Restore power and run a heat cycle; confirm the igniter glows and the burners light cleanly.
Signs You Need a Replacement
- Furnace no-heat with the inducer running but burners not lighting
- Igniter does not glow on a call for heat
- Visible cracks or breaks in the ceramic element
- Repeated ignition lockouts or short cycling on startup
