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 (part number 1009524) provides reliable ignition for the Tempstar T9MPD050F12A4 gas furnace. When the thermostat calls for heat, the control board energizes the igniter; it glows hot to light the burners and, on this integrated igniter/sensor design, also confirms flame presence. Igniters are a normal wear item — repeated heating cycles eventually cause the element to crack or develop hairline fractures. A failed igniter is the most common reason a furnace blows cold air or locks out after several ignition attempts. This OEM HSI restores dependable, fast ignition.
