I have a 2001 kitchenaid superba, the freezer is working fine, but the refrigerator side will not cool causing things to spoil. I've checked the defrost assembly in the freezer side, vacuumed the coils underneath the fridge side, unplugged and replugged, checked the door seals, everything is running fine, but the fridge will not cool. Is it the air diffuser? Also there is alot of water that leaks from underneath the unit while running what would cause this. The model number is KSRS27FGSS14. Please help, would really like to not have to keep everything in the freezer. Oh, all the fans are running properly. I've checked everything that I could think of, thank you and have a great day!
