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 (part number 1009524, IGNITOR/SENSOR HSP) is the ignition component for your Tempstar T9MPD075F12A4 gas furnace. On a call for heat the control board energizes the igniter, which heats to a glowing temperature and ignites the gas at the burners; on this HSP-style design the same element also serves the flame-proving function. Hot surface igniters are brittle and degrade with every heating cycle, eventually cracking or developing high resistance. When the igniter fails, the furnace draws the inducer and opens the gas valve but never lights — typically locking out after several failed attempts and flashing an ignition-fault code.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel to expose the igniter at the burner assembly.
Document — Photograph the igniter position, bracket, and wire routing before removal.
Remove — Unplug the igniter connector and remove the mounting screw; handle the old igniter by its ceramic base only.
Install — Mount the new igniter without touching the element with bare fingers, align it to the burner per your photo, and reconnect the plug.
Test — Restore power and confirm the igniter glows and the burners light cleanly on a call for heat.
