Possible Causes
Refrigerant leak in evaporator or tubing, Partially blocked capillary tube, Restricted filter drier, Internally damaged compressor with low pumping capacity
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration system unless you are a licensed technician with proper equipment.
Owner checks:
- Frost pattern: If you can access the evaporator, inspect the frost. A small frost patch near the inlet and warm rest of coil indicates a sealed system issue.
- Noise and heat: A very hot compressor and condenser with poor cooling also suggest sealed system problems.
- Professional service: Contact a Sharp-authorized or licensed refrigeration technician. They can perform leak detection, evacuate and recharge the system, or replace the compressor or evaporator as needed.
