Overview
This genuine OEM hot surface igniter (HSI, Part No. 1172533) lights the burners on the Tempstar T8MPV075F14B1 gas furnace. On each call for heat the control board energizes the igniter, it glows red-hot, and it ignites the gas as the two-stage gas valve (compatible PN 1172822, Honeywell VR8205Q) opens. Hot surface igniters are brittle silicon-carbide elements that wear out — a cracked, eroded, or electrically open igniter is among the most common no-heat failures. Look for a furnace that cycles through its sequence but never lights, an igniter that no longer glows, repeated ignition lockouts, or a visibly cracked element. Handle the replacement only by its ceramic base, since oils from bare hands can shorten igniter life.

Compatibility
Direct OEM fit for the Tempstar T8MPV075F14B1 furnace and shared across many ICP-family furnaces sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands. Pairs with the 2-stage Honeywell VR8205Q gas valve (PN 1172822) used on this model. Confirm your furnace uses a hot surface igniter (not a spark system) before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker and verify zero voltage with a multimeter; shut off the gas if servicing near the valve.
- Access — Remove the burner compartment service panel.
- Document — Photograph the igniter position and wiring before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw(s); lift the fragile igniter out without bumping the element.
- Install — Mount the new igniter handling only the ceramic base, align it to the burner per your photo, and reconnect the harness.
- Test — Restore power and gas, call for heat, and confirm the igniter glows and the burners light cleanly.
Signs You Need a Replacement
- Furnace runs the ignition sequence but burners never light.
- Igniter no longer glows or glows weakly.
- Furnace locks out after several failed ignition attempts.
- Visible crack, blister, or erosion on the igniter element.
