What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TNE100J20B1 — Silicon Nitride | 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 TNE100J20B1 — Silicon Nitride | 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, HSP-SK) is the ignition component for the Tempstar TNE100J20B1 gas furnace. When the thermostat calls for heat, the control board energizes this igniter; its element heats to over 2,000°F to light the burners, and the integrated sensor function confirms flame. A failed igniter is one of the most common no-heat causes on this furnace platform. The silicon-nitride-style element resists thermal shock better than older silicon carbide igniters, but it still wears out over years of cycling. A cracked or worn igniter produces no glow, a weak glow, or repeated ignition lockouts where the furnace tries several times and then shuts down.

Document — Photograph the igniter position, bracket, and connector routing.
Remove — Unplug the igniter connector and remove the mounting screw(s); handle the old igniter by the ceramic base only — never touch the element.

Test — Restore power, call for heat, and watch for a clean glow, burner light-off, and steady flame.
