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 component that lights the gas burners on your Tempstar T8MPT100F14B1 furnace. On every call for heat the control board sends line voltage to the igniter, which glows white-hot and ignites the gas as the valve opens. Hot surface igniters are the most common furnace failure point because the element is brittle and degrades with each thermal cycle. Typical failure signs are no heat with the inducer running, a furnace that goes through its sequence but never lights, or a visible crack in the igniter element. This furnace pairs the igniter with a two-stage gas valve (OEM #1172822, VR8205Q); if you are servicing the ignition system, inspect both. This listing is the direct OEM igniter replacement matched to the F14B1's burner assembly.

Compatibility

Designed for the Tempstar T8MPT100F14B1 gas furnace. The same HSI is used across matching ICP-family furnaces (Tempstar, Heil, Comfortmaker) sharing this burner platform. Verify the OEM part number and the igniter's mounting bracket and plug style against your original before installing.

Installation Guide

Safety First — Shut off gas and electrical power, then verify zero voltage at the igniter connector with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photograph the igniter's position and wiring connector before removal.
Remove — Unplug the igniter harness and remove the mounting screw; handle the old element only by its ceramic base.
Install — Mount the new igniter without touching the glow element with bare fingers, then reconnect the harness.
Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

Furnace runs the inducer and sequence but never ignites.
Igniter element is cracked, broken, or shows no glow.
Intermittent ignition or repeated lockouts on cold starts.
Burners light late, causing a small roll-out or delayed ignition noise.
