The genuine OEM Lennox 55W22 is a Copeland ZP24K5E-PFJ-830 scroll compressor rated at 19,500 BTUh, built for 220/240V, 50 Hz single-phase R-410A systems. This compressor draws in low-pressure refrigerant vapor and compresses it, driving the refrigerant circuit that delivers cooling throughout your Lennox equipment.
Common failure symptoms include the condenser fan spinning while the compressor stays silent, repeated breaker trips, insufficient or no cooling, excessive noise or vibration, and hard-starting. Electrical shorts, seized bearings, or worn scroll sets typically signal the end of the compressor's service life.
Why OEM matters: R-410A operates at significantly higher pressures than older refrigerants, so the compressor must be precisely rated for it. The genuine Lennox 55W22 is factory-matched to your unit's capacity and 50 Hz electrical supply, ensuring correct oil charge, proper displacement, and dependable protection. Choosing OEM preserves system efficiency and warranty coverage that aftermarket alternatives can jeopardize.
