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 OEM hot surface igniter (part number 1009524) is the ignition component for the Tempstar TNE125J20A1 gas furnace. It is a durable silicon-nitride "SmartLite"-style igniter/sensor that electrically heats to roughly 2,500°F to light the burners on each call for heat. Compared to brittle silicon-carbide igniters, the silicon-nitride element resists cracking from repeated thermal cycling and contamination, delivering longer service life. When this igniter fails the furnace will typically attempt ignition, fail, and lock out — leaving you with no heat, repeated retries, or a control board flashing an ignition-failure code.
