What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TDE125J20B2 — HSI | 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 TDE125J20B2 — HSI | 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 OEM Tempstar hot surface igniter and sensor kit (part #1009524) ignites the burners on each call for heat. When 24V is applied, the silicon-carbide/nitride element glows white-hot and lights the gas as it crosses the burners; the integrated sensor confirms flame. A failed igniter is one of the most common causes of no-heat calls — the furnace cycles the inducer and gas valve but never lights, or it ignites then shuts down on a failed flame-proving sequence. Igniter elements are brittle and degrade with every heating cycle, so replacement is routine maintenance on older furnaces.

Built as a direct OEM replacement for the Tempstar TDE125J20B2 gas furnace and compatible Heil, Comfortmaker, and ICP-family models using igniter kit 1009524. Verify your existing igniter part number and mounting before installing.

Installation Guide

Safety First — Disconnect power and shut off the gas; verify zero voltage with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photo the igniter mounting position and wire connector routing.
Remove — Unplug the igniter connector and remove the mounting screw; handle the element only by its ceramic base, never the hot surface.
Install — Mount the new igniter, reconnect the plug, and confirm proper clearance to the burner.
Test — Restore gas and power, then run a full heat cycle to verify ignition and flame proving.
