Can anyone help me? I've be noticing a puddle of dampen on the top shelf of my fridge, the water seem to be coming from a small U shaped vent at the back. Its a slow drip. Also on the extraordinarily back of the top shelf the river and some of the other food keeps freezing. I on the same wavelength the temperature for a while. Its still cold enough and food out of danger but the water keep coming and its still freezing. I have a Kemore refrigerator next to the freezer up top. No water dispensor or anything fancy more or less it. I think its roughly speaking 5-7 years old(came witht he house). I don't want to call sear because they have lousy customer service especially for repair. Can anyone make clear to me what might be wrong, what should I check?
Answers:    I have found that the characteristic of Sears appliances (particularly Kenmore) is about like as their customer service.

Anyway, when a refrigerator goes through the defrost cycle, it injects thaw out air into the freezer to defrost any frost that may have accumulate. This water is routed to a drip vessel at the bottom of the refrigerator where it evaporates because of steam from the compressor.

There's a drain at the bottom of the freezer box where this condensate is collected. If the hose that routes this marine down to the drip pan is leak, the water will overrun down into your refrigerator box instead.

I don't know if you can get access to this hose minus taking the whole refrigerator apart (I know how they work, but I don't know how to fix them). Maybe you can access it from the backbone or remove it from inside the freezer box. But, I'll bet that's your problem.
i have same problem, agree to me know what answers you get please.
