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/sensor kit (part number 1009524) is the ignition component for the Tempstar T8MPN075B12A1 gas furnace. On a call for heat, the control board energizes the igniter; it glows red-hot and ignites the gas at the burners, while the integrated sensing function confirms flame so the gas valve stays open. Hot surface igniters are a high-wear part — repeated thermal cycling makes the element brittle until it eventually cracks. A failed igniter is one of the most common causes of a furnace that clicks, draws, but never lights. Installing the correct OEM igniter restores fast, reliable ignition and proper flame verification.
