What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model T8MPN100J20B2 — HSI with VR8205S Gas Valve | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 number 1172533, IGNITOR HSI) provides reliable ignition for your Tempstar T8MPN100J20B2 gas furnace, and this listing also covers the matching Honeywell VR8205S snap-mount gas valve (part number 1175705, VALVE N HSI SNAP HW VR8205S) used in the same ignition system. On a call for heat the HSI glows white-hot to light the burner gas while the gas valve meters fuel to the manifold. Igniters are brittle and wear out with every cycle, and a stuck or failed gas valve will prevent ignition entirely. Typical symptoms include a furnace that tries to start but never lights, no glow from the igniter, ignition-failure lockouts, or no gas flow to the burners. Handle the igniter element only by its ceramic base — skin oils shorten its life.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, shut off the gas supply, and verify zero voltage with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photograph the igniter bracket, gas valve wiring, and gas piping connections before disconnecting.
Remove — Unplug the igniter and carefully withdraw it; if replacing the valve, disconnect the wiring and gas line and unsnap/unthread the old valve.
Install — Mount the new igniter by its ceramic base and, if applicable, install the VR8205S valve, reconnecting wiring and gas piping per your photo.
Test — Restore gas and power, leak-check all gas connections with soap solution, then run a heat call and confirm the igniter glows and the burner lights and stays lit.
