Overview
This OEM variable speed blower motor kit (part #1173044) is the ECM (electronically commutated) motor that moves conditioned air through your Tempstar T8MPV050B12A1 furnace and duct system. Rated at 1/2 HP, the variable speed design ramps airflow up and down smoothly for quieter operation, better dehumidification, and higher efficiency than a standard PSC motor. The kit includes the motor and the matched components needed to drop into your blower assembly. A failing variable speed motor may surge or hunt, run intermittently, throw motor-fault codes at the control board, or stop entirely — leaving you with no airflow on heat or cool calls even though the burners or compressor are running. This genuine OEM replacement preserves the factory airflow programming and connector pinout for your unit.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter and allow the motor module to fully discharge.
- Access — Remove the blower-compartment service panel and slide out the blower assembly.
- Document — Photograph the motor control connector, ground, and blower-wheel position before disconnecting.
- Remove — Disconnect the control module harness, loosen the blower-wheel set screw, and separate the failed motor from the housing.
- Install — Mount the new motor, set the blower wheel to the original depth, reconnect the harness exactly as photographed, and reinstall the assembly.
- Test — Restore power, run heat and cool calls, and confirm smooth ramp-up airflow with no fault codes.
