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 hot surface igniter/sensor (HSP SK, part number 1009524) is the ignition component for the Tempstar TDE075B12G1 gas furnace. The hot surface igniter glows red-hot when the control board calls for heat, igniting the gas at the burners. This kit combines the igniter with the flame-sensing function so the furnace can confirm a flame is present and keep the gas valve open. A failed igniter is one of the most common causes of a no-heat furnace: the burners never light, or the furnace locks out after several failed ignition attempts. The brittle silicon igniter element naturally degrades with every heating cycle and eventually cracks or stops glowing.

Installation Guide

Safety First — Shut off gas and disconnect electrical power. Verify zero voltage at the furnace with a multimeter.
Access — Remove the furnace blower-compartment service panel to reach the burner assembly.
Document — Photograph the igniter mounting position and wiring connector before removing anything.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old igniter only by its ceramic base; never touch the element.
Install — Mount the new igniter/sensor in the same orientation, taking care not to touch the silicon element with bare fingers. Secure the screw and reconnect the plug.
Test — Restore gas and power, then run a heat cycle. Confirm the igniter glows, the burners light cleanly, and the flame holds without lockout.

Signs You Need a Replacement

Furnace clicks/attempts to start but burners never light (no-heat call)
Igniter no longer glows or only glows dim/uneven
Furnace lights then shuts down on flame-sense failure
Visible cracks, blistering, or white deposits on the igniter element
