Wagner WG840466 115V Direct Drive Furnace Blower Motor 3/4–1/5 HP PSC Multi-Speed HVAC Replacement Motor

Condition: New in retail box; box shows significant shelf wear, tape, scuffs, creases, torn cardboard areas, edge wear, and handling marks.

The Wagner WG840466 Direct Drive Furnace Blower Motor is a universal-style replacement motor designed for direct-drive HVAC blower applications in residential and light commercial forced-air systems. This motor is made for furnace blower assemblies where the motor shaft directly drives the blower wheel without a belt. It is a single-phase permanent split capacitor motor rated for 115 VAC, 60 Hz operation and supports multiple horsepower applications, including 3/4 HP, 1/2 HP, 1/3 HP, 1/4 HP, and 1/5 HP. Its multi-speed wiring, reversible rotation, and broad cross-reference range make it useful for HVAC service replacement where the original motor specifications match the installation requirements.

Wiring Notes

The wiring diagram on the box shows a typical PSC multi-speed blower motor layout:

• White: Line / common
• Black: High speed
• Blue: Medium-high speed
• Yellow: Medium-low speed
• Red: Low speed
• Brown and Brown/White: Capacitor leads
• Yellow/Green: Ground

The direction wiring diagram indicates that rotation can be changed by using the appropriate direction lead combination. Installation should be completed by a qualified HVAC technician, and the technician should verify wiring against the actual motor label before energizing the system.

Assembly and System Use

The WG840466 is intended to be used as part of a direct-drive furnace blower assembly, which may include:

• Furnace or air handler cabinet
• Blower housing / scroll assembly
• Squirrel cage blower wheel
• Motor mounting bracket or belly band
• PSC run capacitor
• Furnace control board or fan relay
• Speed tap wiring
• Ground connection

This motor may replace an existing blower motor when the original equipment requirements match the replacement motor’s voltage, horsepower range, RPM, frame size, shaft diameter, shaft length, capacitor rating, rotation, and mounting style. It should not be selected by horsepower alone.

Installation Considerations

• Verify the original motor horsepower and confirm it falls within the 3/4–1/5 HP range.
• Confirm system voltage is 115 VAC, 60 Hz.
• Match the original motor’s RPM before installation.
• Confirm frame size, mounting style, shaft diameter, and shaft length.
• Use the correct run capacitor rating specified for the motor.
• Select the correct speed tap for proper heating and cooling airflow.
• Confirm rotation before reinstalling the blower assembly.
• Inspect the blower wheel for dirt buildup, cracks, imbalance, and loose set screws.
• Replace weak, swollen, or incorrect capacitors during motor installation.
• Make sure the motor is properly grounded.
• Do not operate the motor outside the correct blower housing unless permitted by the manufacturer’s instructions.
