What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TNE100F14A1 — Silicon Nitride HSI Kit | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TNE100F14A1 — Silicon Nitride HSI Kit | Ships Today.

My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Is this igniter compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This genuine OEM hot surface igniter and sensor kit (part number 1009524, HSP SK) is the ignition component for the Tempstar TNE100F14A1 gas furnace. On a call for heat, 120V is applied to the igniter, which glows red-hot and ignites the gas at the burners; the same silicon nitride element also provides flame proving. A failed igniter is one of the most common causes of no-heat calls — the element becomes brittle with thermal cycling and eventually cracks, leaving the furnace unable to light. Silicon nitride HSI construction resists the thermal shock that breaks older silicon carbide igniters, delivering longer service life and reliable cold-weather starts.

Installation Guide

Safety First — Shut off gas and disconnect electrical power, then verify zero voltage with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photo the igniter bracket position and the wire harness routing before disconnecting.
Remove — Unplug the igniter connector, remove the mounting screw(s), and withdraw the old igniter without touching the ceramic element.
Install — Mount the new igniter by the bracket only (never handle the silicon nitride element with bare fingers), align it to the burner, and reconnect the harness per your photo.
Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

Furnace blows cold air or locks out on ignition failure
