without a model # is hard to help.

one time i ran into this problem and found out the lady was putting hot things in the freezer creating alot of moisture. check your door seal also make sure its sealing if it had gaps you can heat it up with a hairdryer to streach it out.

Hi,

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Probably excessive ice in the condensor. Likely defrost thermostat or defrost heater problem.

What happens is excessive ice keeps airflow from the refrigerator part of the unit.

try checking the fan in the freezer at the top which pushes the coldness over to the freezer

CONTROL SWITCH PROBLEM

in most refridgerator cabins is a air dam at top right of side by side and it could be sticking open and working other times or it could get stuck in defrost cycle due to defrost timer not working properly.defrost timer would be first thing to look to.

I have the same problem. Just talked to a friend that's a great appliance repairman. he said I have to remove the panel in the back inside of freezer and there is a drain that gets clogged up, a little hole or tube.
clean that and should work fine and stop leaking. I haven't had time yet, but this weekend I'll do the deed. Hopes this helps ya!
