Overview
This OEM blower motor kit (part number 1173048) is the 1/2 HP variable-speed (ECM) indoor blower motor for the Tempstar T9MPV050F12B1 gas furnace. The variable-speed motor drives the indoor blower wheel that circulates conditioned air through the home, ramping airflow up and down for quiet operation, better humidity control, and improved efficiency over a single-speed PSC motor. When a variable-speed blower motor fails, you may see no airflow on a heat or cool call, intermittent shutdowns, the blower running at the wrong speed, unusual humming or grinding, or a control board flashing a blower-fault code. Because ECM motors carry an onboard module, always confirm the module and motor are supplied together in this kit and verify the correct wheel rotation on install.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter; ECM modules hold a charge, so wait 5 minutes before touching the motor.
- Access — Remove the blower compartment access panel and slide out the blower assembly.
- Document — Photograph the motor wiring, module connector, and blower-wheel position on the shaft.
- Remove — Disconnect the power and control connectors, loosen the wheel setscrew, separate the wheel, and unbolt the motor from the mount.
- Install — Mount the new motor, fit the blower wheel at the documented depth and tighten the setscrew, then reconnect the power and control harnesses.
- Test — Restore power and run heat and cool cycles; verify the blower ramps smoothly to the correct speeds with no fault codes.
Signs You Need a Replacement
- No blower airflow on a heat or cool call
