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.

Overview

This OEM hot surface igniter/sensor (part number 1009524, HSP SK) lights the burners on your Tempstar furnace and serves as the flame-sensing element during the ignition sequence. When the igniter weakens or cracks it glows dimly or not at all, leaving the furnace to lock out on failed ignition — you'll typically see repeated ignition attempts, short cycling, or no heat at all. A visibly cracked element, blistered coating, or open-circuit reading on the ohmmeter confirms a bad igniter. This durable silicon nitride-style HSP igniter is a direct OEM replacement.
