OEM Lennox Scroll Compressor 53,500 BTUH R-22 — 90W72

The genuine OEM Lennox 90W72 is a Copeland ZR54K5-PFV-800 scroll compressor rated at 53,500 BTUH, 208/230V, single-phase, and built for R-22 refrigerant. This compressor is the driving force of your Lennox condensing unit, pressurizing refrigerant to carry heat from indoors to the outdoor coil. The ZR-series scroll design provides smooth, energy-efficient operation and long service life in residential and light-commercial Lennox systems.

Common failure symptoms: A worn or failing compressor may run without cooling the space, trip the breaker at startup, buzz or hum without starting, cut out repeatedly on its internal overload, short-cycle, or emit grinding, knocking, or rattling noises. Reduced cooling capacity and rising electricity costs are common indicators of a compressor problem.

Why OEM matters: Lennox engineers each unit around a specific compressor's capacity, oil charge, and electrical profile. Installing the factory 90W72 guarantees correct fit, rated efficiency, and full compatibility with your unit's controls and warranty. Since R-22 is a phased-out refrigerant, matching the exact OEM part is especially important for reliable service. Confirm voltage, phase, and refrigerant, and use a licensed technician for installation.
