The genuine OEM Lennox 11B06 (Copeland CR20K6E-PFV-875) is a 17,700 BTUH reciprocating compressor for 208/230V, single-phase, R22 applications. It is the core component of your Lennox condensing unit, compressing refrigerant to move heat out of the conditioned space. Built to exact Lennox factory specification, it matches the capacity, oil charge, and electrical profile of the original.
Common failure symptoms: the system runs without cooling, the compressor buzzes and trips the breaker at startup, knocking or rattling noises from the outdoor unit, repeated overload cycling, or a locked rotor that draws high amperage and fails to start. Shorted or grounded motor windings will also condemn the compressor.
Why OEM matters: Lennox engineers system charge, efficiency ratings, and warranty terms around the factory compressor. A correctly matched 11B06 keeps the sealed system operating at rated capacity and protects downstream components, while an ill-matched aftermarket part can cause oil migration, reduced capacity, and early failure. Replace the filter drier, evacuate properly, and verify charge on installation. Because R22 is a phased-out refrigerant, this part is intended for maintaining existing legacy Lennox systems.
