Emerson K55HXJHT-9121 Multi-Speed Furnace Blower Motor – 1/3 HP, 115V, 1075 RPM, 4-Speed, Frame 48Y

Condition: New – Factory fresh, unused and undamaged. Comes with manufacturer labeling and part number tags.

The Emerson K55HXJHT-9121 is a 1/3 HP, 115V multi-speed blower motor, designed for use in residential and light commercial HVAC systems. With a 4-speed 1075 RPM output, this motor offers flexibility in airflow control, making it suitable for furnace blowers, air handlers, and package systems requiring reliable, consistent performance. Built on a 48Y frame, it features a sleeve bearing, open air-over construction, and is thermally protected to extend operational life.

With a shaft rotation to the left (CCW) when viewed from shaft end, this motor matches many OEM specifications and is commonly used as a replacement motor in popular gas and electric furnace brands. It is also pre-wired for multiple speed taps, supporting efficient fan operation across different heating or cooling modes.
