The genuine OEM Lennox 73W31 is a Copeland ZPS49K4E-PFV-830 scroll compressor rated at 49,200 BTUH, running on 208/230V single-phase power with R-410A refrigerant. This is the primary pumping component in your Lennox outdoor unit, compressing refrigerant vapor to drive the refrigeration cycle and provide the smooth, high-efficiency cooling that Copeland Scroll units are valued for.

Common failure symptoms: Watch for a unit that hums but won't start, breaker trips on startup, weak or no cooling despite the fan running, loud metallic or rattling noises, oil leakage around the compressor base, and windings that read open, grounded, or shorted on a meter. Overheating and repeated thermal-overload cycling are also telltale signs.

The OEM Lennox 73W31 is matched precisely to your system's tonnage, electrical draw, and refrigerant charge, ensuring correct capacity, efficiency, and warranty compliance. Generic compressors risk mismatched displacement and incompatible oil, leading to premature failure. Ships same day so your Lennox system is back online fast.
