If you have a side by side model you need to look at the refrigerator compartment wall on the left of the bottom drawer and move the slide control to the warmer/fruit/vegitable setting instead of the meat setting.
I hope this helped. Please rate my help or ask for more help please. supertechks

i never go by that / just hold my finger over the air port and move it till i feel move air or less to set it the way i need it ,,, less air puts less air into crisper to cut down on freezing

I had the same problem. Apparently the problem is the main control board. According to the technician that came out to fix mine there is a design flaw and these boards are very sensitive and can blow a circuit or malfunction from the slightest power surge. What happens then is that the control board doesn't "tell" the fan to turn on and off at the right time so the fridge and freezer warm up too much before the fan kicks in and then it cools everything down but since the fan isn't running at the correct intervals and circulating the air all of the cold air settles to the bottom which causes the produce in the drawers to freeze while the top shelves get warmer. I had done a fair bit of research before calling GE and came to the conclusion that this was a common problem. So I pressed them and was able to get the fee for the part waived (before I made the service call appointment) which was around $150. The part now has a 5 year waranty which I find funny, because I'm not sure why it wouldn't have that upfront as my refridgerator is only 2 years old. Whatever!! Unfortunately, unless you have indepth knowledge of refridgerator repair there is no way around the service call and labor. Anyone buying a new model of refridgerator (any company) should consider an extended waranty. The service tech also told me that all refridgerators made after 2001 are required, by law, to have an electronic mother board which in all likelyhood will fail at somepoint prior to when you are ready to buy a new fridge!

Good Lucak!

Shut the air flow into the crispers if you can. If not, turn the refrigerator temperature warmer by just a few degrees. The air into the fridge from the freezer is channeled into the crispers.

Emptied drawers and cleared the drain hole. Drawers were then refilled BUT MADE SURE THAT THEY WERE NOT OVERLOADED
