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) serves the Tempstar T8MPV125J20A1 gas furnace. It is a combined silicon-nitride hot surface igniter and flame-sensing element: on a call for heat the control board energizes it to glow and light the burners, and it also confirms flame presence so the board keeps the gas valve open. Silicon-nitride HSP igniters are more durable than older silicon-carbide elements but still fail from thermal fatigue, soot contamination, or cracking. When it fails the furnace will not light, or it will light and then shut down on a flame-sense fault after a few seconds.

Compatibility

Engineered for the Tempstar T8MPV125J20A1 furnace and shared across ICP-family furnaces (Heil, Comfortmaker, Arcoaire, KeepRite) that use the HSP SK silicon-nitride igniter/sensor. Verify the part number and connector against your existing unit before installing.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker and verify zero voltage with a multimeter before handling any wiring.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position, bracket, and harness routing before disconnecting.
Remove — Unplug the connector and remove the mounting screw(s); handle the old igniter by the ceramic base only, never the element.
Install — Mount the new igniter/sensor so the element sits correctly in the burner flame path without touching it bare-handed, then reconnect the harness.
Test — Restore power and confirm the element glows, the burners light, and the furnace holds flame without locking out.

Signs You Need a Replacement
