Overview
This OEM hot surface igniter and flame-sensing kit (part number 1009524) is the factory-specified ignition component for the Tempstar T9MPD080J16A2 gas furnace. The silicon-nitride igniter element heats rapidly when 120V is applied, lighting the burners on each call for heat, while the integrated sensor confirms flame presence so the control board keeps the gas valve open. When this part fails, the furnace will typically lock out after several ignition attempts, leaving you with no heat. Common failure modes include a cracked or pitted igniter element, carbon buildup on the sensor rod, and open circuits from thermal stress.

Compatibility
Designed as a direct OEM replacement for the Tempstar T9MPD080J16A2 furnace and other ICP-family (Tempstar, Heil, Comfortmaker, Arcoaire) 9-series modulating furnaces using the same ignition assembly. Always confirm the part number on your existing igniter before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter and shut off the gas.
- Access — Remove the furnace front service panel.
- Document — Photograph the igniter wiring and bracket position before disconnecting.
- Remove — Unplug the igniter harness connector and remove the mounting screw(s) holding the igniter to the burner assembly. Handle by the ceramic base only — never touch the element.
- Install — Mount the new igniter in the same position, reconnect the harness, and confirm the element sits correctly over the burner port.
- Test — Restore gas and power, then run a heat cycle and verify ignition and flame sensing.
Signs You Need a Replacement
- Furnace clicks and tries to start but never lights (no glow at the igniter).
- Burners light then shut off after a few seconds (failed flame sensing).
- Visible cracks, pitting, or white spots on the igniter element.
- Repeated ignition lockouts or short-cycling on heat.
