Overview
This OEM hot surface igniter and sensor kit (part #1009524) is the component that lights the burners on your Tempstar T8MPV050B12A1 furnace. On a heat call, the control board sends voltage to the igniter, which glows red-hot to ignite the gas as the valve opens; the integrated sensor confirms flame so the board keeps the valve energized. Hot surface igniters are brittle and degrade with every heating cycle, eventually cracking or losing the ability to reach ignition temperature. When that happens you'll hear the inducer and gas valve cycle but get no flame, often followed by a lockout after three or four failed attempts. This genuine OEM igniter/sensor assembly restores reliable ignition with the correct resistance, glow temperature, and mounting bracket for your unit.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position, bracket, and wire harness routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter handling it only by the ceramic base, reconnect the harness, and confirm correct burner alignment.
- Test — Restore power, initiate a heat call, and watch for a clean glow, burner ignition, and stable flame sensing.
Signs You Need a Replacement
- Furnace cycles the inducer and gas valve but never ignites
- Visible crack or no glow on the igniter element
- Repeated ignition-failure lockouts after several attempts
- Short-cycling caused by intermittent flame loss
