The same thing happened to me. The vents in the freezer are probably plugged with ice, chip away the ice on the vents in the freezer and it will go back to normal, the fridge is warmer because it's not getting any of the cooling from the freezer.

sounds like the compressor quit running and it's defrosting because of it. It should also have a drain hose that goes down to the evaporator try in the bottom and chances are it's also plugged.

Water supply to ice maker may be leaking.

Get an old-fashioned thermometer and put it in the freezer. A mercury thermometer will do fine or anything else available. It should read about +5F after being in the freezer for 5 minutes or so. Also, what is leaking-----is it water?? Is the frig powered----check the inside light----it should come on when the frig door is opened.

I think its just defrosting

I am noticing a slow drip coming from the back of the refrigerator dripping from the freezer it's dead center in the middle and even on the top of the refrigerator (inside) I see you wetness I'm not sure if the refrigerator seems warmer I swear it does. I also haven't notified it kick on. It used to make a louder sound and not just very quiet my freezer stuff still seems frozen but I did put Popsicles in a little while ago (3 hours ago) and they aren't frozen yet I'm going to check on them later any ideas
