What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model T8MPN100F20A1 — HSP SK | 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 T8MPN100F20A1 — HSP SK | 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 is the OEM hot surface igniter/sensor kit (part number 1009524, IGNITOR/SENSOR HSP SK) for the Tempstar T8MPN100F20A1 gas furnace. This combination component both ignites the burners and confirms flame presence. On a call for heat, the igniter glows hot to light the gas, then verifies the flame so the control board keeps the gas valve open. Because it is exposed to repeated thermal cycling and direct flame, it is a normal wear item that eventually cracks, weakens, or fails. When it does, the furnace may fail to light entirely, or light briefly and then shut down on a flame-sense lockout, leaving you without reliable heat.
