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 (HSI) is the direct-fit ignition component for the Tempstar T8MPL075F16B1 gas furnace. The igniter is a silicon-carbide element that glows red-hot when energized by the control board, lighting the gas at the burners on every call for heat. Because it cycles each heating cycle, the igniter is among the most common furnace wear parts. OEM part numbers covered: 1172533 (IGNITOR HSI) and the related 1172821 (VALVE N HSI SNAP HW VR8205S) gas-valve assembly referenced for this model. Typical failure symptoms include no ignition, a furnace that clicks but never lights, a cracked or visibly fractured igniter element, or a unit that locks out after repeated failed ignition attempts.
