What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TDE050B12A1 — Silicon Nitride HSI/Sensor Kit | 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 TDE050B12A1 — Silicon Nitride HSI/Sensor Kit | 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 is the genuine OEM hot surface igniter and sensor kit (part #1009524) for the Tempstar TDE050B12A1 gas furnace. The igniter glows red-hot to light the gas burners at the start of every heating cycle. This silicon-nitride-style HSI/sensor service kit resists thermal shock and delivers reliable ignition. When the igniter fails, the blower may run without producing heat, the furnace may attempt ignition repeatedly before locking out, or the control board throws an ignition-failure fault. A cracked or worn igniter is among the most common no-heat causes on this furnace.
