The genuine OEM Lennox 12Y49 is an Interlink APA032TAA scroll compressor rated at 29,800 BTUH, designed for 575V three-phase systems running R-410A refrigerant. This compressor is the driving force of your outdoor unit, compressing and circulating refrigerant to power the cooling cycle throughout your Lennox equipment. The three-phase scroll design offers smooth, balanced, and highly efficient operation suited to commercial installations.

Common failure symptoms: Indicators of a failing compressor include no cooling, overload or breaker trips at startup, loud metallic or grinding noises, excessive heat at the condensing unit, or a compressor that hums without starting. Internal winding or mechanical failure means the unit needs to be replaced.

Why OEM matters: The factory Lennox 12Y49 guarantees the correct 575V three-phase electrical characteristics, capacity, and R-410A compatibility your system was built around. Three-phase equipment requires precise component matching to protect phase rotation, charge balance, and rated efficiency. Choosing the genuine OEM compressor preserves reliability and any remaining Lennox warranty.
