The Lennox 49M86 is a genuine OEM ZP20K3E-PFV-830 scroll compressor rated at 20,000 BTUH (approximately 1.7 tons) for 208/230V, single-phase, R-410A systems. As the driving force of your outdoor condensing unit, it compresses R-410A refrigerant to move heat out of your home and sustain the cooling cycle. The scroll design offers quiet, energy-efficient performance as a direct, factory-matched replacement for compatible Lennox air conditioners and heat pumps.
Common failure symptoms: Signs of a failing compressor include a unit that no longer cools, warm air from the registers, tripped breakers, loud humming or knocking from the outdoor unit, short-cycling, or a compressor that buzzes but doesn't start. These usually indicate worn scrolls, electrical winding failure, or loss of compression.
Why OEM matters: The genuine Lennox 49M86 is built to the exact capacity, R-410A pressure rating, and electrical specification your equipment demands. Because R-410A systems run at elevated pressures, the correct OEM compressor is essential for safe, dependable operation, safeguards your unit's rated efficiency, and helps maintain your Lennox warranty.
