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.

Overview

This OEM hot surface igniter/sensor (Tempstar part 1009524) is the combination ignition and flame-proving component for the Tempstar T8MPT100J20A1 gas furnace. It glows hot to light the burner gas and then verifies that flame is present, allowing the control board to keep the gas valve open. When this igniter/sensor degrades, the furnace either fails to light at all or lights briefly and shuts down on a flame-sense fault, short-cycling the system. Installing a fresh OEM unit restores both dependable ignition and stable flame proving in a single part.
