Rcd hd46mq134 Ecm Blower Motor 3/4 Hp 1050 Rpm 115/120V

Product Description

The RCD hd46mq134 is an ECM blower motor designed for forced-air HVAC systems requiring consistent, controlled airflow. Rated at 3/4 HP and 1050 RPM, it operates on 115/120 volts at 50/60 Hz in single-phase configurations. The counterclockwise rotation direction is factory-set and must be confirmed before installation. At 15.76 pounds, this is a substantial motor built for residential air handler and furnace blower applications. Licensed HVAC technicians install this part as a direct OEM-style replacement to restore proper airflow distribution across the conditioned space, eliminating uneven temperature zones caused by motor failure or degraded performance.

The hd46mq134 is suited for residential forced-air systems where an ECM blower motor is required in the air handler or furnace blower assembly. ECM motors are commonly specified in higher-efficiency systems because they modulate speed more precisely than PSC motors, supporting better humidity control and reduced energy draw during part-load operation. This motor fits applications where a counterclockwise-rotation, single-phase, 115/120-volt ECM unit is the specified replacement type.

Key Features

• ECM motor technology for variable-speed blower control in forced-air HVAC systems
• 3/4 HP output at 1050 RPM for dependable airflow delivery
• 115/120V, 50/60 Hz, single-phase operation suits standard residential electrical supply
• Counterclockwise rotation — confirm direction matches existing blower assembly before installation
• Compact footprint at 12 x 11 x 11 inches for drop-in serviceability

Compatibility

Designed as an OEM-style ECM blower motor replacement for residential forced-air HVAC systems requiring a single-phase, 115/120-volt, counterclockwise-rotation motor at 3/4 HP and 1050 RPM.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the air handler or furnace before removing the existing motor. Verify rotation direction, voltage, and HP rating against the unit nameplate before installing this motor. Follow NEC requirements for electrical connections and consult the equipment manufacturer service manual for motor mounting and wiring harness procedures.
