Tempstar Hot Surface Igniter for TNE075F14A1 — Silicon Nitride HSI | Ships Today

Overview

This OEM hot surface igniter (HSI) kit, part number 1009524, ignites the burners in your Tempstar TNE075F14A1 gas furnace. Built on a durable silicon-nitride element, it reaches ignition temperature within seconds and doubles as a flame sensor (IGNITOR/SENSOR HSP SK). When the igniter fails, the furnace will draw inducer and open the gas valve but never light, leaving you without heat. Common failure signs include a cracked or pitted element, a glowing igniter that fails to ignite gas, or repeated lockouts after several attempts. A fresh igniter restores dependable, on-demand heating.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter and shut off the gas supply.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter bracket position and wire routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; carefully withdraw the ceramic-based igniter without touching the fragile element.
5. Install — Mount the new igniter in the same orientation, handling only the ceramic base, and reconnect the harness per your photo.
6. Test — Restore gas and power, then run a heat cycle to confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Furnace runs the inducer but never lights the burners.
• Visible cracks, blisters, or white spots on the igniter element.
