The genuine OEM Lennox 11B85 is a Copeland scroll compressor that serves as the core of your Lennox outdoor cooling unit. It pressurizes and circulates refrigerant to transfer heat out of your home, using smooth scroll compression for quiet, energy-efficient, and dependable performance. This compressor is built to Lennox specifications, matching the precise displacement, voltage, and refrigerant charge your system requires.

Common failure symptoms: A failing 11B85 may cause the system to run without cooling, hum or buzz but fail to start, trip the circuit breaker, or produce loud grinding and rattling sounds. Overheating, hard-starting, and shorted or grounded motor windings are common indicators that the compressor has reached the end of its service life.

Why OEM matters: Because the compressor is the most valuable and vital part of your air conditioner, exact matching is non-negotiable. The OEM Lennox 11B85 delivers correct capacity, oil compatibility, and electrical fit, protecting your system's efficiency and warranty in ways generic replacements cannot. For a lasting repair, always replace the liquid-line filter drier at the same time.
