The genuine OEM Lennox 11G52 is a tandem scroll compressor assembly based on the ZP39K5E-TF5-898, rated at 39,000 BTUH per module for 200/230V, 3-phase R-410A systems. Two scroll compressors are joined on a shared manifold to provide staged cooling capacity, allowing your Lennox unit to run a single compressor at low demand and both together at peak load. This design improves part-load efficiency, comfort, and refrigerant management in larger residential and light-commercial Lennox systems.

Common failure symptoms: One stage no longer cooling, a compressor that buzzes but fails to start, tripped breakers, poor oil equalization between the tandem pair, loud knocking or vibration, or repeated overload trips. A single failed compressor in the assembly compromises staging and overall capacity.

Why OEM matters: The factory-specified 11G52 is matched to Lennox's exact capacity, oil-balance, and 200/230V electrical specifications, ensuring proper tandem staging and preserving warranty coverage. Non-OEM substitutions risk oil-imbalance and premature failure of both compressors. Choose the authentic OEM assembly for a guaranteed fit and dependable staged cooling in your Lennox equipment.
