You could have a leaky door gasket. If you have an icemaker there could
be issues because of that also, but I bet its the gasket. Door gaskets
aren't the easiest fix usually. They often involve removing the liner
and if you don't seat them just right you will still have the same
problem. You might want to consider hiring a repairman. I would.

Good luck-

Hello,
We have a side by side whirpool refrigerator that is about 3 years old
and
we are seeing a lot of frost/ice build up in the top and walls of the
freezer section.

What is this build up caused by? How do we fix it?

The freezer appears to be cooling well.

Thanks much!
