The Lennox 55W27 is a genuine OEM scroll compressor (Copeland ZP54K5E-PFJ-830) rated at 44,200 BTUH for 220/240V, single-phase, 50 Hz operation with R-410A refrigerant. This compressor is the core of your Lennox condensing unit, compressing and circulating high-pressure refrigerant to move heat out of your building. Purpose-built for R-410A systems, it operates at the higher pressures modern refrigerant demands while maintaining efficient, low-vibration scroll performance.
Common failure symptoms: A failing 55W27 often presents as warm air from the vents while the outdoor fan spins, hard-starting or clicking on the overload, elevated amp draw, or a compressor that trips the breaker. You may also notice unusual noise, oil staining around the base, or the unit repeatedly shutting down on thermal protection.
Why OEM matters: The factory 55W27 is matched to your Lennox system's capacity, voltage, and oil charge, ensuring correct R-410A compatibility and rated efficiency. Non-OEM compressors risk capacity mismatches, warranty issues, and premature failure. Order the genuine part for guaranteed fit and reliable, long-term cooling.
