What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TCK050F12B1 — Silicon Nitride HSI w/ Sensor | 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 TCK050F12B1 — Silicon Nitride HSI w/ Sensor | 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 (part number 1009524) is the silicon-nitride HSI for the Tempstar TCK050F12B1 gas furnace. On each call for heat, the control board energizes this igniter; it glows white-hot to light the burners. Silicon nitride elements are far more rugged than legacy silicon-carbide igniters, resisting thermal shock and lasting through many more ignition cycles. When this part fails you get the classic no-heat symptom: the inducer runs and the gas valve opens, but the burners never light and the furnace locks out.
