The Lennox 10P62 is a genuine OEM ZPS51K5E-TF5-830 two-stage scroll compressor rated at 52,100 BTUH (approximately 4 tons) and designed for 200/230V, 3-phase, R-410A systems. As the heart of your outdoor condensing unit, this compressor circulates and pressurizes refrigerant to move heat out of your home, and its two-stage scroll design delivers quieter operation and improved part-load efficiency compared to single-stage units.
Common failure symptoms include the unit failing to cool, a compressor that hums or trips the breaker on start-up, loud grinding or knocking noises, tripped internal overload protection, or a system that runs continuously without reaching setpoint. A compressor that is electrically shorted, seized, or has lost its ability to build pressure must be replaced.
Why OEM matters: the 10P62 is factory-matched to Lennox capacity, electrical, and refrigerant specifications, ensuring correct displacement, oil charge, and terminal configuration. Using the exact OEM compressor protects your system warranty, avoids mismatched-capacity problems, and guarantees reliable, rated performance for your Lennox equipment.
