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 #1172533) is the ignition component for the Tempstar T9MPD050F12C2 modulating gas furnace, designed to work with the Honeywell VR8205S snap-mount gas valve system (related valve #1175705). When the thermostat calls for heat, the control board energizes the igniter, which heats to roughly 2,000°F and lights the gas burners as the valve opens. The igniter is the most replaced ignition part in modern furnaces because the heating and cooling cycles eventually crack the element. Typical failure symptoms are a furnace that runs the inducer and opens the gas valve but never ignites, followed by a lockout. A no-glow igniter, visible cracks, or white deposits on the element all point to replacement.
