The Lennox 29M33 is a genuine OEM ZR68KC-TF5-830 scroll compressor rated at 70,000 BTUH and built for 200/230V, 3-phase, R-22 systems. As the heart of your outdoor condensing unit, it compresses refrigerant vapor and drives it through the cooling cycle — without a healthy compressor, the system cannot move heat and cooling stops entirely.

Common failure symptoms: a unit that hums or clicks but won't start, tripped breakers, warm air from the supply vents, loud grinding or knocking noises, or a compressor that trips its internal overload and shuts down repeatedly. Burned electrical terminals and locked-rotor conditions are also frequent signs a scroll compressor has failed.

Why OEM matters: the 29M33 is engineered to Lennox's exact displacement, oil charge, and electrical specifications, ensuring correct capacity, efficiency, and long service life. Aftermarket substitutes can mismatch the refrigerant, tonnage, or terminal configuration, risking premature failure and voided warranty coverage. Installing the factory-specified compressor protects the rest of your Lennox system and restores rated performance.
