Possible Causes
Pin-hole leak in evaporator, Corroded condenser tubing, Poorly brazed joint at compressor or filter drier, Mechanical damage to refrigerant lines
How to Fix / Troubleshooting
Safety: Unplug the wine cooler. Do not attempt to repair the sealed system yourself; refrigerant handling requires certification.
- Visual inspection: Look for oily residue on copper lines, around the evaporator, or near the compressor connections—this often indicates a leak.
- Check cooling performance: If the compressor runs continuously but the cabinet does not cool, a leak is likely.
- Do not operate with a suspected leak: Running the compressor with low refrigerant can cause further damage.
- Contact a licensed technician: A professional must locate the leak, repair the tubing, replace the filter drier, evacuate, and recharge the system to Grundig specifications.
