Overview
This genuine OEM hot surface igniter (HSI, Part No. 1172533) ignites the burners on the Tempstar T8MPV075F14C1 gas furnace. On a call for heat the control board energizes the igniter, it glows red-hot, and it lights the gas as the two-stage gas valve (compatible PN 1172822, Honeywell VR8205Q) opens. Hot surface igniters are brittle and degrade over time — a cracked, eroded, or open igniter is one of the most common causes of no-heat calls. Typical symptoms include the furnace running through its sequence but never lighting, an igniter that no longer glows, repeated ignition lockouts after several failed attempts, or a visibly cracked igniter element. Handle the new igniter only by its ceramic base — skin oils on the silicon carbide element can shorten its life.

Compatibility
Direct OEM fit for the Tempstar T8MPV075F14C1 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 or direct-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.
