What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model T8MPT100F14A1 — OEM 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 T8MPT100F14A1 — OEM 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 OEM hot surface igniter/sensor (Part #1009524, HSP SK) lights the gas burners and helps prove flame on your Tempstar T8MPT100F14A1 furnace. On each call for heat the control board powers the igniter, which glows white-hot and ignites the gas as the valve opens. The combined igniter/sensor design both starts and confirms combustion, so a degraded element can cause hard starts, no ignition, or false flame-loss lockouts. Hot surface igniters are the most frequently replaced furnace part because the element is fragile and wears out with repeated thermal cycling. Look for a furnace that runs its sequence but never lights, an igniter that won't glow, or a visibly cracked element. This is the direct OEM kit matched to the F14A1's burner assembly.

Compatibility

Access — Remove the burner compartment service panel.
Document — Photograph the igniter's position and wiring connector before removal.
Remove — Unplug the harness and remove the mounting screw; handle the old element only by its ceramic base.

Test — Restore gas and power, start a heat call, and confirm the igniter glows, the burners light, and flame is proven without lockout.
