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 (HSI), part #1172533, is the ignition component for the Tempstar T9MPD075F12C1 modulating gas furnace. The igniter energizes on each heating call, glowing red-hot to ignite the gas at the burners. Hot surface igniters are the single most common furnace ignition failure: the brittle silicon-carbide/silicon-nitride element cracks from thermal cycling, soot, or simple age. Typical failure symptoms include the furnace running its blower but producing no heat, a glow that is dim or absent through the inspection port, or the unit locking out after several failed ignition attempts. This is a direct-fit replacement that matches the original element resistance and mounting bracket — no modification required. The related gas valve (#1172821, Honeywell VR8205 series) is also used on this model; order it separately if your diagnosis points to the valve.

Installation Guide

Access — Remove the burner-compartment service panel.
Document — Photograph the igniter wiring and bracket position before disconnecting.
Remove — Unplug the igniter connector and unscrew the mounting bracket. Handle the old element by the bracket only — never touch the igniter tip.
Install — Mount the new igniter, confirming the tip sits in the correct burner-flame path without touching metal. Reconnect the plug.
Test — Restore gas and power, then run a full heat cycle and confirm a strong glow and clean burner light-off.
