FASCO D703 1/2 HP Blower Motor

This direct-drive blower motor delivers 1/2 horsepower for HVAC air-handling applications. It operates on 208-230V AC single-phase power at 60 Hz with a permanent split capacitor design. The unit suits technicians replacing worn furnace or air-handler motors in residential and light-commercial systems.

Replaces 1/3 HP and 1/4 HP units

The motor covers three nameplate horsepower ratings — 1/2, 1/3 and 1/4 HP — so one model can replace several older sizes. Three-speed operation at 1,075 RPM lets the installer match airflow to the existing duct design. The upgrade is worth it when the original motor runs hot, trips its thermal protector or can no longer maintain required static pressure.

Fits 48-frame stud mounts with 26 in leads

A 48-frame open dripproof enclosure bolts to standard stud mounts and the 26-inch leads reach common control boxes without splicing. Auto-reset thermal protection and Class B insulation support continuous duty at up to 40 °C ambient. The motor is approved for 208 V operation but not for 200 V systems. Clockwise or counter-clockwise rotation is selected on site.

Questions about this item

Will the 48-frame stud-mount pattern fit my existing furnace housing?

The motor uses a 48-frame stud mounting type; verify your housing matches that bolt pattern before ordering.

How do I wire the three-speed PSC motor correctly for 208-230 V single-phase power?

Connect the incoming 208-230 V line to the common and the desired speed tap; the motor is usable at 208 V but not at 200 V, and rotation is reversible by swapping leads.

When should I plan to replace the capacitor or bearings on this continuous-duty blower?

The motor runs continuous duty at up to 40 °C ambient with auto thermal protection; expect capacitor or bearing service after several heating seasons depending on run hours.
