The correct replacement for Tempstar model TNK075F14B1 — Silicon Nitride Ignitor/Sensor | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 OEM hot surface igniter/sensor (part number 1009524) is the silicon-nitride HSI that lights the burners on your Tempstar furnace. On a call for heat, the control board energizes the igniter; it glows white-hot and ignites the gas as the valve opens. A cracked or worn igniter is one of the most common causes of no-heat calls: the furnace runs its inducer and tries to light, but the burners never fire and the unit locks out. Silicon nitride igniters are more durable and impact-resistant than older silicon-carbide "glow bar" styles, but they still degrade with thousands of ignition cycles.

Compatibility

Direct OEM fit for the Tempstar TNK075F14B1 gas furnace and shared across many ICP-family furnaces (Tempstar, Heil, Comfortmaker) that use this silicon-nitride hot surface igniter assembly. Confirm the connector style and mounting bracket match your existing igniter before installing.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter; shut off the gas supply.
Access — Remove the furnace burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wiring connector before disconnecting.
Remove — Unplug the igniter harness and remove the mounting screw(s); handle the old igniter by its base only.
Install — Mount the new igniter without touching the silicon-nitride element, align it to the burner, and reconnect the harness.
Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

Furnace tries to ignite but burners never light (no-heat lockout).
Igniter shows cracks, blistering, or no longer glows.
