The Lennox 89M19 is a genuine OEM ZR16KA-PFV-830 scroll compressor rated at 15,500 BTUH (approximately 1.3 tons) for 208/230V, single-phase, R-22 systems. As the heart of your outdoor condensing unit, this compressor circulates and pressurizes refrigerant to move heat out of your home. Its scroll design delivers quiet, efficient, and reliable operation as a direct factory replacement for compatible Lennox air conditioners and heat pumps.
Common failure symptoms: A failing compressor often shows up as a unit that won't cool, warm air from the supply registers, hard-starting or repeated tripping of the breaker, loud grinding or humming noises, or the outdoor unit buzzing but not starting. Electrical shorts, seized bearings, or loss of compression are typical end-of-life failures.
Why OEM matters: Choosing the genuine Lennox 89M19 ensures the exact displacement, electrical characteristics, and mounting specifications your system was engineered around. OEM compressors protect your equipment's rated efficiency and capacity, and using a factory-matched part helps preserve warranty coverage and long-term reliability that generic substitutes can't guarantee.
