Important Notes Before Replacement
Refrigerant compatibility: This model is normally R-22. If your system has been converted to R-410A or R-32, you cannot directly replace with this compressor — the oil type and compression design differ.
Electrical & capacitor match: Ensure the start/run capacitor and overload protector match your unit’s requirements.
Nameplate check: Always match model numbers on the compressor nameplate or service manual to avoid mismatches.
