OEM Lennox Scroll Compressor 57,500 BTUH R-22 — 25M84

The genuine OEM Lennox 25M84 is a ZR57KC-TF5-830 scroll compressor rated at 57,500 BTUH for 200/230V three-phase systems running R-22 refrigerant. This compressor drives the refrigeration cycle in your Lennox commercial or residential unit, compressing and circulating refrigerant to move heat out of the conditioned space. The scroll mechanism provides efficient, low-vibration performance and excellent reliability under demanding light-commercial loads.

Common failure symptoms: Watch for a system that cycles on but produces no cooling, tripped breakers or blown fuses, excessive noise or vibration, overheating, or a compressor drawing high amperage. On three-phase units, a reversed rotation after a phase swap can also prevent proper operation. Internal electrical shorts, mechanical seizure, or loss of compression typically require full replacement.

Why OEM matters: Lennox matches each compressor to a specific tonnage, refrigerant, and voltage/phase profile. The factory 25M84 guarantees correct 57,500 BTUH capacity and R-22 compatibility, protecting downstream components and maintaining rated efficiency. Because R-22 systems are legacy equipment, using the exact OEM replacement keeps your existing charge and metering devices properly matched. Trust the genuine Lennox part for a precise fit and long service life.
