The genuine OEM Lennox 18X97 rotary compressor (equivalent to internal part 50N6229) is the heart of your Lennox cooling system, circulating and compressing refrigerant to drive the entire refrigeration cycle. Engineered to Lennox factory specifications, this rotary compressor delivers the efficiency and quiet operation your system was designed to provide.

When a compressor begins to fail, you'll often notice warm air from the vents, the outdoor unit tripping the breaker, loud humming or clicking, or the compressor failing to start altogether. A seized or electrically shorted compressor is one of the most common causes of a complete cooling loss in a Lennox condenser.

Choosing OEM matters: the 18X97 is matched to the exact displacement, electrical characteristics, and mounting geometry of your Lennox equipment. Aftermarket substitutes can create capacity mismatches, void your warranty, and shorten system life. Install a factory-correct compressor to restore rated performance and protect your investment.
