Tempstar Hot Surface Igniter for TCK100J16B1 — Silicon Nitride | Ships Today

Overview

This OEM hot surface igniter/sensor (part #1009524, HSP-SK style) lights the burners on your Tempstar TCK100J16B1 furnace. When the control board calls for heat, the igniter's silicon-nitride element heats to roughly 2,000°F to ignite the gas, then serves as the flame-proving sensor. Silicon nitride elements are far more durable and shock-resistant than older silicon-carbide igniters. A failed igniter is one of the most common no-heat causes: the inducer runs and the gas valve clicks, but the burners never light, and the furnace locks out after several retries. Cracked or no-glow igniters cause hard starts, delayed ignition "booms," and repeated lockout codes.

Specifications

Compatibility

Direct-fit replacement for the Tempstar TCK100J16B1 and compatible ICP-family furnaces (Heil, Comfortmaker) using the HSP silicon-nitride igniter platform. Handle the element only by the ceramic base — skin oils shorten igniter life.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter; shut off the gas supply.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter bracket position and connector before removing.
4. Remove — Unplug the igniter harness and remove the mounting screw(s); withdraw the old igniter without touching the element.
5. Install — Seat the new igniter at the correct depth over the burner, secure the bracket, and reconnect the harness.
6. Test — Restore gas and power, then watch a full ignition cycle confirm glow, burner light, and stable flame sense.

Signs You Need a Replacement

• No glow from the igniter on a call for heat.
• Furnace locks out after several ignition attempts.
• Visible crack or break in the igniter element.
• Delayed ignition or a noticeable "whoomp" at startup.
