Wagner Motors WG840586 Furnace Blower Motor 1/3 Hp

Product Description

The WAGNER MOTORS WG840586 is a permanent split capacitor, direct drive furnace blower motor rated at 1/3 HP and designed for residential forced-air heating and cooling systems. Operating on 208 to 230 volts AC at 60 Hz, it draws 2.8 amps and runs at 1075 RPM. The motor features three selectable speeds and a reversible rotation, giving HVAC technicians flexibility during installation and system commissioning. Built on a 48 NEMA frame with Class B insulation and ball bearings, it is engineered for sustained operation under the thermal demands typical of furnace air-handler service.

This motor is suited for direct drive blower applications in residential and light commercial gas furnaces and air handlers. The flexible mounting configuration supports shaft-up, shaft-down, and belly band orientations, making it adaptable to a wide range of blower cabinet layouts. A gray-green powder coat finish provides corrosion resistance. The required run capacitor is a 370-volt AC type; the specific MFD rating is noted on the motor carton. HVAC technicians installing or replacing motors in cramped blower compartments will find the extended mounting bolts and large, easy-to-read wiring diagrams useful during service calls.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the furnace or air handler before removing the existing motor or making any wiring connections. Verify the run capacitor MFD rating matches the value printed on the motor carton before energizing. Consult the included wiring diagram and applicable local codes before completing the installation.
