OEM Lennox Scroll Compressor 28,400 BTUH 208/230V R-22 — 90W68

The 90W68 is a genuine OEM Lennox ZR28K5-PFV-800 Copeland scroll compressor rated at 28,400 BTUH, 208/230V, R-22 refrigerant, single phase. As the heart of your outdoor condensing unit, the compressor pressurizes and circulates refrigerant through the system, driving the entire cooling cycle. This scroll design delivers quiet, efficient operation with fewer moving parts than older reciprocating compressors, and it is engineered to match the exact electrical and capacity specifications of the Lennox systems it was built for.

Common failure symptoms: the unit runs but won't cool, the compressor hums or clicks but won't start, tripped breakers, hard starts, loud grinding or rattling noises, or a compressor that overheats and shuts down on thermal overload. A failed compressor is the most common reason an outdoor unit stops producing cold air.

Why OEM matters: installing the factory-specified 90W68 ensures correct displacement, oil charge, and electrical draw for your Lennox equipment, protecting warranty coverage and delivering the rated efficiency and lifespan. Aftermarket substitutes can mismatch capacity or R-22 compatibility, leading to premature failure. Always have a licensed HVAC technician recover refrigerant and install this compressor.
