The genuine OEM Lennox 10P64 is a Copeland ZP51K5E-TFE-830 scroll compressor kit rated at 52,100 BTUh, running on 575V 3-phase power with R-410A refrigerant. As the heart of your Lennox condensing unit, this compressor circulates and compresses refrigerant to drive the entire cooling cycle. Supplied as a complete kit, it includes the hardware needed for a proper factory-grade installation.
Common failure symptoms: A failing compressor often shows up as warm air at the registers, a unit that hums or clicks but won't start, tripped breakers, loud grinding or rattling noises, or a system that short-cycles. Locked rotors and burned windings are typical end-of-life signs on high-hour scroll compressors.
Why OEM matters: The 10P64 is engineered to Lennox's exact displacement, electrical, and refrigerant specifications. Using the factory-matched scroll set ensures rated capacity, proper oil charge compatibility, and reliable operation with your unit's existing controls and metering device — protecting your warranty and avoiding the efficiency losses and premature failures common with universal substitutes.
