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 Tempstar hot surface igniter (part 1009524) is the component that lights your furnace burners on every heat cycle. When the control board calls for heat, the igniter electrically heats to a glowing temperature and ignites the gas as it flows across the burners; this igniter/sensor design also helps confirm flame is present. Hot surface igniters are brittle and wear out over time, and they are the single most common reason a gas furnace fails to light. A cracked or burned-out igniter will not glow, leaving you with a blower that runs but no heat.
