The genuine OEM Lennox 12U79 is an Interlink APA026MAA scroll compressor rated at 28,000 BTUH, 380V (max), 3-phase, with a 22–60 Hz operating range for R-410A refrigerant. The wide frequency range indicates variable-speed/inverter-driven operation, allowing your Lennox unit to modulate capacity precisely to match demand — improving comfort, efficiency, and quiet running compared with fixed-speed compressors.

Common failure symptoms: Signs of trouble include the unit failing to reach setpoint, inverter or control fault codes, the compressor not ramping up, breaker trips, unusual vibration or noise, overheating, and short-cycling. On inverter systems, erratic capacity, communication faults, and loss of cooling often accompany a failing compressor.

Why OEM matters: Variable-speed compressors are tightly matched to their inverter drive and control board, so only the factory-specified 12U79 ensures correct communication, displacement, oil charge, and electrical characteristics for your Lennox system. Using the genuine OEM part protects rated efficiency, inverter compatibility, and warranty coverage. Verify voltage, phase, refrigerant, and drive compatibility before installation, and always have a qualified HVAC technician perform the replacement.
