The Lennox 81W08 is a genuine OEM Interlink ABA042KAA scroll compressor rated at 42,500 BTUH for 208/230V, single-phase systems running R-410A refrigerant. As the core of your outdoor unit, this scroll compressor continuously circulates and pressurizes refrigerant, enabling the heat transfer that keeps your home cool.

Common failure symptoms: the condenser hums or clicks but the compressor won't start, the breaker trips on demand for cooling, supply air runs warm, or the unit produces loud grinding and vibration. A locked rotor, shorted windings, or tripped internal overload are common signs the scroll compressor has failed.

Why OEM matters: the 81W08 is engineered to Lennox's precise capacity, oil charge, and single-phase electrical spec for R-410A operation. Aftermarket compressors can introduce refrigerant or tonnage mismatches that reduce efficiency and shorten equipment life. Choosing the factory-authorized part ensures a proper fit, full rated performance, and continued warranty protection for your Lennox system.
