Overview
This OEM 1/2 HP, 4-speed blower motor (part 1185447) is the factory-correct air-moving motor for the ICP/Tempstar/Heil WFAR100C048C1 furnace. It drives the blower wheel that circulates conditioned air through your ductwork in both heating and cooling modes. The four speed taps let the installer match airflow (CFM) to the system's heating and cooling requirements. A failing blower motor causes weak airflow, overheating limit trips, noisy or intermittent operation, and eventually no air movement at all. Replacing it with the exact OEM motor preserves the original airflow design, bearing quality, and electrical ratings.

Installation Guide
- Safety First — Disconnect power at the switch and breaker; verify zero voltage with a multimeter.
- Access — Remove the blower compartment panel and slide out the blower assembly.
- Document — Photograph all motor and capacitor wiring and note the speed tap connections.
- Remove — Mark the blower wheel position, loosen the setscrew, remove the wheel, and unbolt the old motor from the mount.
- Install — Mount the new motor, reinstall the wheel at the same depth, reconnect the run capacitor, and wire the speed taps per your photo.
- Test — Restore power and confirm the blower starts smoothly, runs quietly, and moves strong airflow on each active speed.
