Genuine OEM Lennox 36W59 Copeland ZP34K5E-TF5-830 scroll compressor. Rated at 34,600 BTUH on 200/230V, 3-phase power for R-410A refrigerant, this compressor drives your Lennox system by pressurizing and circulating refrigerant to reject heat through the outdoor condenser coil. The ZP-series scroll mechanism is purpose-built for R-410A's higher operating pressures, providing smooth, efficient, and durable compression.
Common failure symptoms: A worn or failed compressor typically produces warm air from the vents, a system that hums but won't start, loud grinding or knocking, repeated tripping of the breaker or overload, and a noticeable drop in cooling capacity. Locked internals and shorted windings are common failure modes.
Why OEM matters: The 36W59 is matched to your Lennox unit's 200/230V 3-phase supply and R-410A refrigerant. Installing the correct OEM compressor restores factory-rated performance, protects your warranty coverage, and eliminates the capacity and electrical mismatches that cause generic parts to fail early. Always have a licensed HVAC professional handle evacuation, brazing, and recharging.
