Gibson refrigerator, large size The compressor is sound and working, guaranteed The fan is sound The internal fan is sound The upper heater is sound The lower heater is sound The screen is working The refrigerator freezes, and God knows best, maybe a sensor. I took it apart for repair at home and I don't know what its problem is. I didn't take it to a workshop. Whoever takes it for parts or to fix it. Electricity: 110
