The Lennox 15M85 is a genuine OEM Copeland ZR57K3-TF5-830 scroll compressor rated at 57,200 BTUH (roughly 4.75 tons) for 200/230V, 3-phase, R-22 applications. This compressor drives the refrigeration cycle in your Lennox outdoor unit, drawing in low-pressure vapor and discharging high-pressure refrigerant to enable heat rejection at the condenser coil. Scroll technology ensures smooth, efficient, and quiet operation with excellent long-term reliability.

Common failure symptoms: A worn or failed compressor may run without cooling the space, trip breakers, hum but fail to start, produce loud grinding or clattering sounds, draw excessive current, or shut down repeatedly on internal overload protection. Burnt terminals or a grounded motor winding are clear signs of end-of-life failure.

Why OEM matters: The factory 15M85 matches your Lennox system's precise displacement, 200/230V 3-phase electrical rating, and oil specification. Substituting a generic compressor risks capacity mismatch, electrical faults, and voided warranty coverage. This genuine OEM part restores full rated performance and protects the longevity of your Lennox equipment.
