The genuine OEM Lennox 19H71 tandem compressor assembly is a 460V, 3-phase unit designed for commercial Lennox equipment operating on three-phase power. A pair of compressors work in tandem to deliver staged capacity, letting the system modulate output to match cooling load for improved efficiency and consistent comfort. Serving as the refrigerant pump at the center of the cooling circuit, this assembly powers the heat-transfer process throughout your Lennox system.
Common failure symptoms include a system that won't cool, tripped breakers, loud grinding or knocking, a compressor that hums but doesn't start, rapid cycling, and abnormally high amp draw. Overheating or shorted internal windings on a 3-phase compressor almost always require full replacement.
Why OEM matters: The 19H71 is matched to your unit's tonnage, refrigerant charge, and 460V 3-phase electrical supply. Installing the factory-specified assembly guarantees correct voltage compatibility, proper fit, and rated output while keeping your Lennox warranty valid. Confirm your equipment is 460V 3-phase before ordering, and rely on a licensed HVAC technician to recover refrigerant, evacuate the system, and verify phasing and charge during installation.
