Overview
This OEM variable speed blower motor kit (part number 1173048) is the factory replacement for the Tempstar T9MPV050F12A1 gas furnace. Rated at 1/2 HP, this ECM (electronically commutated motor) drives the indoor blower wheel that circulates conditioned air through your duct system. Variable speed motors ramp up and down smoothly to deliver quieter operation, better humidity control, and improved energy efficiency compared to single-speed PSC motors. Common failure symptoms include the blower not starting, intermittent operation, excessive noise or grinding, the furnace overheating and tripping the limit switch, or weak airflow at the registers. Because this is a complete kit, it includes the motor and the hardware needed to drop it into your existing blower housing.

Compatibility
Engineered as the direct OEM replacement for the Tempstar T9MPV050F12A1 variable speed gas furnace. Because Tempstar, Heil, Comfortmaker, and other ICP-family furnaces share components, this motor kit may also fit equivalent models built on the same platform.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the lower blower compartment service panel.
- Document — Photograph all motor and control connections, including the motor harness plug and ground, before disconnecting.
- Remove — Slide the blower assembly out, remove the wheel set screw, separate the old motor from the housing, and transfer the blower wheel to the new motor.
- Install — Mount the new motor in the housing, reinstall the blower wheel, reseat the assembly, and reconnect the harness exactly per your photos.
- Test — Restore power and run a heating and cooling cycle to confirm the blower ramps smoothly and airflow is correct.
