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 (HSP type) provides both ignition and flame-sensing for the Tempstar T8MPN100F14A1 gas furnace. Built on a rugged silicon-nitride element, the HSP design is far more durable than legacy silicon-carbide igniters and resists the cracking and burnout that cause no-heat failures. When this igniter/sensor degrades, the furnace fails to light or drops out shortly after ignition because flame is no longer proven. Replacing it restores reliable lighting and proper flame verification. This part references OEM 1009524 (IGNITOR/SENSOR HSP SK).
