HVAC/R General-Purpose Motor For: Fasco, Packard SM121, D121, 82121

Safety first: Have a qualified technician disconnect and verify isolation of all power before service. Diagnose the cause of overheating or motor failure before replacement, and never bypass thermal protection or improvise wiring.

Restore quiet, reliable airflow with this ERP replacement general-purpose shaded-pole motor for compatible HVAC/R equipment, cross-referenced to Fasco and Packard motors. A failed motor leaves fans silent, hums without spinning, or overheats; this open-enclosure motor restores operation in compatible applications. It runs 115VAC at 60Hz, 0.9A, 1550 RPM, 1/70 HP, with a 3.3-inch diameter and 6-inch leads, rotating counterclockwise viewed from the shaft end, and has four mounting studs at each end. Match the original ratings, mounting, and rotation before ordering; cross-references identify motors, not complete appliance model compatibility.
