I have exactly the same problem....even after cleaning the Freezer; this still occurs. My freezer is on the bottom of the Refridgerator...maybe this is my problem as well. Can't wait for the responses you receive. Terry from Canada
I was thinking that maybe something leaked and then froze at the bottom. This is from the fridgidaire site: Door could be ajar slightly or gasket not making contact with cabinet. Check for seal. Doors remaining open for long periods of time will cause moisture and frost to accumulate. The moisture will disappear after a period of time. Humid weather will cause moisture and frost to accumulate faster and this is normal. If moisture is between doors, turn off your power saver switch located near the control box on some models.
Also: One way to make sure your seals are good is to stick a dollar in between the door and freezer and if it can be moved around, the seal may need to be replaced. Also try vasoline to help the seal 'connect' a little better.
