Overview
This is a genuine OEM variable speed blower motor kit (part number 1173048) for the Tempstar T9MPV050F12A3 variable-speed gas furnace. The 1/2 HP ECM (electronically commutated motor) drives the indoor blower wheel, moving conditioned air through the supply ductwork at precisely modulated speeds for quiet, efficient, even comfort. Because it is a variable speed ECM, it ramps up and down smoothly rather than cycling full-on/full-off, which improves humidity control and lowers operating noise. Common failure symptoms include the blower not starting, intermittent operation, loud humming or grinding from worn bearings, weak airflow, or the furnace control flashing a blower/motor fault code. The kit includes the motor and the components needed for a complete replacement.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the lower blower compartment service panel.
- Document — Photograph the motor wiring, the ECM control connector, and the blower wheel position on the shaft before disconnecting anything.
- Remove — Disconnect the motor harness and control plug, loosen the blower wheel set screw, pull the wheel, then unbolt the motor from the blower housing.
- Install — Mount the new motor, reinstall the blower wheel at the documented depth, torque the set screw to the flat, and reconnect the harness exactly per your photos.
- Test — Restore power, run a heating and a cooling call, and confirm the blower ramps smoothly through its speed stages with no vibration or noise.
