Lennox 78A95 Motor

For mid-sized air handlers and condenser units, the Lennox 78A95 Blower Motor serves as a high-performance 1/2 HP replacement motor designed to maintain critical airflow in residential and light commercial HVACR systems. Operating at 208-230V, this single-phase (1Ph) motor features a 1075 RPM rated speed with 3-speed taps, allowing technicians to fine-tune CFM delivery based on static pressure requirements and specific system ductwork. This direct drive blower motor is a 48-frame powerhouse commonly found in Lennox CHA8, CHP8, and GCS3 series units, offering the reliability needed for 24/7 climate control applications.

As a veteran-grade OEM HVAC motor, the 78A95 utilizes a permanent split capacitor (PSC) design to ensure consistent torque and high operational efficiency. The multi-speed blower motor configuration provides the flexibility required for balanced heating and cooling cycles. When swapping out a failed unit, verify your capacitor rating—typically a 10 MFD/370V for this class—as a weak capacitor is the leading cause of premature winding failure. This motor is engineered for CCWLE rotation (Counter-Clockwise Lead End) to match standard Lennox blower wheel orientations.

• Versatile 3-Speed Performance: Three distinct speed taps allow for precise airflow adjustment across various tonnage requirements.
• Broad Compatibility: Drop-in replacement for Lennox part numbers 78A9501 and P-8-5329, fitting a wide range of packaged units and air handlers.
• Rugged Construction: Built to withstand high-ambient temperatures and continuous duty cycles in demanding environments.
• Direct Drive Efficiency: Eliminates the maintenance and mechanical loss associated with belt-driven assemblies.

What is the rotation of the Lennox 78A95?
This motor is configured for Counter-Clockwise Lead End (CCWLE) rotation, which is standard for many Lennox blower assemblies.

Can I use this motor on a 115V circuit?
No, this motor is specifically wound for 208-230V single-phase power. Applying 115V will prevent the motor from reaching torque and will lead to immediate failure.

Should I replace the capacitor at the same time?
Yes. It is standard trade practice to replace the run capacitor whenever installing a new PSC motor to ensure the start-and-run windings operate within spec and avoid overheating.
