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 genuine OEM hot surface igniter and sensor kit (part #1009524, HSP SK) ignites the burners on the Tempstar T8MPN150J20A1 gas furnace. When the control board calls for heat, 120V is applied to the igniter, which glows incandescent to light the gas at the burner. A modern silicon-nitride style igniter is more durable than legacy silicon-carbide elements, but it still degrades with thousands of ignition cycles and eventually cracks or fails to reach ignition temperature. A bad igniter is the single most common no-heat furnace failure. This kit provides the correct element and mounting hardware for a direct OEM replacement.
