Liebherr Refrigerator, model HC1001, serial number 271323884. Refrigerator Issue: The compressor is working, and I can hear it running. The upper refrigeration compartment is not cooling. The lower freezer compartment’s rear panel feels cool. The refrigerator technician, after inspection, said that the refrigerant in the upper cooling section of the fridge has leaked, while the lower section is still cooling. Both fans are working, but the computer control is preventing them from rotating. Finding the leak in the upper cooling section would be very difficult, and they do not recommend repairing it. However, all other parts of the fridge are functioning properly. If anyone is interested in the old refrigerator or any second-hand parts from the disassembled unit, please come to pick them up on your own. We do not provide transportation services.
