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 (part number 1009524, HSP SK) is the ignition source for the Tempstar TNK100J16A1 gas furnace. On a call for heat, the control board energizes the igniter; it glows red-hot and ignites the gas at the burners. The same HSP element also serves a sensing function in this design, confirming flame so the board keeps the gas valve open. Hot surface igniters are the most common furnace failure point — the brittle silicon-carbide element cracks with thermal cycling, age, or rough handling. When it fails, the furnace will not light and typically locks out on an ignition fault.

Compatibility

Installation Guide

Safety First — Disconnect power and shut off the gas; verify zero voltage with a multimeter before working near the burners.
Access — Remove the burner/control compartment service panel.
Document — Photograph the igniter position, bracket, and wire routing before disconnecting.
Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old element. Never touch the new igniter's surface with bare fingers — skin oils shorten its life.
Install — Mount the new igniter so it sits correctly in the burner flame path, secure the screw, and reconnect the plug per your photo.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light reliably.
