My 2 year old refrigerator, freezer is always frosty, almost snow-like inside. What do I need to do to fix it? Fresh food compartment part seems fine.

Liz for Model Number frigidaire FPUI2188LF1

ANSWER Hello Liz, The frost is where humidity has gotten into the unit and, since it's in the freezer, as soon as it condenses, it freezes. I would use a mirror and a flashlight and inspect the door seal all the way around to insure it is making good contact all the way around the door. If it is, check the fresh food door seal. Of course, if there's an air leak around the fresh food door seal, water will condense on the fresh food ceiling. It is possible that if you have an ice maker and it is connected to the hot water supply, the hot water going into the ice maker can be causing this issue. If you do find an area that isn't contacting the cabinet, you can heat it with a hair dryer to make the seal conform. When it cools back down, it will maintain the shape it was in when it cooled. If there are any tears in the door seal 241872505, it will have to be replaced. The door seals will last the lifetime of the appliance if they are kept clean and dry, so if you ever have a spill, after the spill is cleaned up, clean the door seal also because if the door closed with the spill in place, the door seal will wind up being sticky and this will tear up the seal over time.
