What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model T9MPD050F12A3 — Silicon Nitride OEM | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T9MPD050F12A3 — Silicon Nitride OEM | Ships Today.

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 (HSP SK), OEM part number 1009524, lights the burners on the Tempstar T9MPD050F12A3 gas furnace. On a call for heat the control board energizes the igniter, it glows to a high temperature, and the gas valve opens to ignite the burners; the same silicon-nitride element also confirms ignition. Silicon nitride igniters are far more durable and shock-resistant than older silicon carbide "flat" igniters. When this igniter fails, the furnace ignites no flame and locks out — leaving you with no heat and often a flashing fault code.
