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 1172533) is the factory ignition component for the Tempstar T9MPD075F12C2 gas furnace. The durable silicon-nitride element glows to ignition temperature within seconds when 120V is applied, lighting the burners on every heat call. This furnace platform pairs the igniter with a Honeywell VR8205S snap-mount HSI gas valve (OEM 1175705); together they form the ignition and gas-delivery system. When the igniter cracks or opens, the furnace clicks, attempts to start, and then locks out without heat.
