The genuine OEM Lennox 14F82 is a Copeland ZR57K3E-TFE-830 scroll compressor rated at 58,500 BTUH, 575V, 3-phase, for R-22 systems. This compressor is the workhorse of your Lennox condensing unit, raising refrigerant pressure and circulating it through the system to reject heat and cool your space. Its scroll construction offers quiet operation, high efficiency, and long service life.
Common failure symptoms: the system stops cooling, the compressor hums but won't start or trips the breaker, loud knocking or rattling, a tripped internal thermal overload, or windings that measure open or grounded at the terminals. Oil staining at the base and frequent short-cycling indicate the compressor is failing.
Why OEM matters: the factory-specified 14F82 matches the precise capacity, 575V 3-phase electrical requirements, oil charge, and mounting footprint your Lennox unit needs. An OEM compressor maintains rated system efficiency, protects warranty coverage, and eliminates the capacity and electrical mismatches that plague aftermarket alternatives. Confirm the voltage, refrigerant type, and model compatibility before you install, and always fit a new liquid-line filter drier during a compressor replacement.
