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 (part number 1172533, "IGNITOR HSI") is the burner ignition component for the Tempstar T9MPV100J20C1 two-stage gas furnace. At the start of every heating cycle the igniter glows red-hot to light the gas at the burners. On this two-stage furnace the igniter operates alongside the Honeywell VR8205Q 2-stage gas valve (related OEM part 1172822, "VALVE N&L HSI 2STG HW VR8205Q"). A worn or cracked hot surface igniter is the single most common no-heat failure — the inducer runs and the valve opens, but with no glow the burners never light and the control board drops into ignition lockout.

Installation Guide

Safety First — Turn off power at the disconnect and breaker, verify zero voltage at the board with a multimeter, and shut off the gas supply.
Access — Remove the lower burner-compartment service panel.
Document — Photograph the igniter bracket position, depth, and wiring before disconnecting.
Remove — Unplug the igniter connector, remove the mounting screw, and withdraw the old igniter — handle the replacement by its ceramic base only.
Install — Seat the new igniter at the correct burner-port depth, secure the bracket, and reconnect the harness as photographed.
Test — Restore gas and power, run a heating cycle, and confirm the igniter glows, both stages light cleanly, and no flame-failure lockout occurs.

Signs You Need a Replacement
