Overview
This OEM hot surface igniter (HSI, part number 1172533) ignites the burners on the Tempstar T8DNL075F16B1 gas furnace and is paired here with the matching Honeywell VR8205S HSI snap gas valve (part number 1172821). On a heat call, the control board energizes the igniter; it glows red-hot, and once it reaches temperature the gas valve opens and the burners light. Hot surface igniters are the most common no-heat failure point — the silicon carbide or silicon nitride element is brittle and degrades with every cycle. The bundled VR8205S valve provides the safe, sequenced gas flow that the HSI ignition system depends on. If the furnace clicks but never lights, the igniter rarely glows, or you see repeated lockouts, this kit restores reliable ignition.

Compatibility
Designed for the Tempstar T8DNL075F16B1 furnace and the ICP/Tempstar/Heil T8DNL platform using hot surface ignition with a VR8205S snap-action gas valve. Verify your furnace uses HSI (not spark or pilot) ignition before ordering.
Installation Guide
- Safety First — Shut off the gas supply, disconnect power at the switch and breaker, and verify zero voltage with a multimeter.
- Access — Remove the burner compartment service panel.
- Document — Photograph the igniter bracket position and all gas valve wiring before disconnecting.
- Remove — Unplug the igniter harness and unscrew the igniter, handling it only by the ceramic base — never touch the element. If replacing the valve, disconnect wiring and unthread the gas connections.
- Install — Mount the new igniter so the element sits correctly in the burner flame path; install the valve and reconnect gas and wiring per your photo. Leak-check all gas joints with soap solution.
- Test — Restore gas and power, run a heat cycle, and confirm the igniter glows, the valve opens, and the burners light smoothly.
Signs You Need a Replacement
- Igniter does not glow on a heat call
- Visible cracks, blistering, or a broken element
- Furnace clicks but burners never light
