Freezer condensation

I have a side by side Ref. Freezer. The first 5 coils at the top are not icy like the rest. Lots of condensation and leaking. What part do you think is the problem. I look forward to your response! Thanks:confused:

Although we recieved no response, I think that we have fixed the water dripping out of the freezer. We changed the Defrost Thermostat.:slight_smile:
