OEM Lennox Scroll Compressor 39,000 BTU 575V R-410A — 55W30

The genuine OEM Lennox 55W30 is a Copeland ZP39K5E-TFE-830 scroll compressor rated at 39,000 BTUH, operating on 575V, R-410A refrigerant, and 3-phase power. As the primary component of your Lennox condensing unit, it compresses and circulates high-pressure R-410A refrigerant to drive the heat-transfer cycle that produces cooling. The ZP-series scroll design is purpose-built for R-410A applications, delivering quiet, efficient, and reliable operation, and this unit is a direct factory-matched replacement for compatible 575V 3-phase Lennox systems.

Common failure symptoms: Signs that the compressor has failed include a system that runs but produces little or no cooling, breakers tripping at startup, loud grinding or humming, a compressor that won't start (hard-start or locked rotor), and short-cycling. Open, shorted, or grounded windings and repeated internal overload trips typically confirm the 55W30 is at the end of its life.

Why OEM matters: Lennox builds each unit around exact compressor specifications, and R-410A's high operating pressures make the correct rating essential. Installing the genuine OEM 55W30 ensures proper displacement, POE oil charge, and 575V 3-phase electrical characteristics, restoring full capacity and rated efficiency while preserving warranty coverage. Generic replacements risk pressure and oil incompatibility, capacity mismatch, and early failure.
