Wagner Motors wg840588 Furnace Blower Motor 1/2 Hp

Product Description

The WAGNER MOTORS wg840588 is a direct drive PSC blower motor designed for ducted residential gas furnace applications. Rated at 1/2 HP and 1075 RPM with 3 speeds, it operates on 208-230 volt single-phase power at 60 Hz and draws 2.7 amps full load. The motor features Class B insulation and an automatic thermal overload protector for reliable service. A 5.625-inch body diameter and belly band mounting make it a straightforward drop-in replacement in standard 48-frame blower assemblies. The 36-inch lead wires provide enough slack to reach terminal blocks without splicing, reducing install time in tight air handler cabinets.

This motor is intended for ducted forced-air heating systems where a direct drive blower arrangement is used. It is electrically reversible, allowing the installer to match the rotation direction required by the blower wheel without stocking a separate part. Sleeve bearings and an open enclosure suit the filtered indoor airstream environment typical of residential furnace applications. HVAC technicians handling blower motor replacements on residential and light commercial gas furnaces will find the three-speed winding and standard belly band mount compatible with a wide range of OEM blower decks.

Key Features

• 1/2 HP output at 1075 RPM with 3 selectable speeds for airflow adjustment
• Electrically reversible rotation eliminates the need for a separate CW or CCW motor
• Automatic thermal overload protector guards against winding damage from locked-rotor or high-ambient conditions
• Class B insulation rated to 130 degrees F rise for sustained duty in high-ambient furnace cabinets
• 36-inch leads ease wire routing and terminal connections in confined blower compartments
• Belly band mount fits standard 48-frame mounting brackets without modification

Compatibility

Designed as an OEM-style replacement for direct drive ducted furnace blower motors using a standard 48-frame belly band mount and a 1/2-inch by 5-inch shaft.

Installation Notes

A licensed HVAC technician should shut off power at the disconnect and verify zero voltage with a meter before removing the existing motor. Discharge or disconnect the run capacitor before handling motor leads. Confirm shaft length and rotation direction before final assembly, and verify the replacement capacitor rating matches the 10 MFD / 370-volt specification required by this motor. Work should comply with local mechanical codes and NEC requirements for motor branch circuits.
