OEM Lennox Scroll Compressor 32,600 BTUH 575V — 11C38

The genuine OEM Lennox 11C38 is a ZR32K5E-TFE-800 scroll compressor rated at 32,600 BTUH, 575V, R-22, single-phase. This scroll compressor serves as the heart of your Lennox condensing unit, compressing and moving refrigerant through the system to remove heat and deliver efficient, low-noise cooling — engineered to Lennox factory tolerances for a straightforward, direct replacement.

Signs that a compressor is failing include warm air at the supply registers, an outdoor unit that hums but won't start, tripped breakers, hard starting, grinding or knocking noises, and short-cycling that never satisfies the thermostat. An internal short or mechanical seizure will bring cooling to a complete stop.

Installing the correct OEM Lennox 11C38 compressor is essential to match your system's designed capacity, refrigerant and oil charge, and 575V single-phase supply. Generic replacements risk capacity mismatch, shortened lifespan, and voided warranty coverage. The factory part preserves rated efficiency and long-term reliability. Refrigerant must be properly recovered and installation completed by a licensed HVAC technician.
