The genuine OEM Lennox 420 is an Interlink APA032RAA scroll compressor rated at 30,000 BTUh, designed for 208/230V three-phase R-410A systems. This compressor compresses low-pressure refrigerant vapor and pumps it through the condenser and evaporator, powering the complete cooling cycle in your Lennox unit.

Common failure symptoms include the compressor humming without starting, tripped breakers or blown fuses, weak or absent cooling, abnormal vibration and noise, and frequent short-cycling. Failed motor windings, a locked rotor, or damaged scroll flanks typically mean the compressor has reached the end of its life.

Why OEM matters: R-410A's high operating pressures and three-phase power require a compressor matched exactly to the system's tonnage and electrical spec. The genuine Lennox 420 provides the correct displacement, rotation direction, and factory-rated performance your equipment depends on. Installing OEM protects your system's efficiency and warranty, avoiding the compatibility and longevity problems that plague aftermarket replacements.
