It sounds like unit is not properly going into defrost or your evaporator fan motor is starting to go bad

is your freezer one you have to defrost manually or it is a automatic defrost style, if it's manual defrost ,the frost i suspect has built up and pushing the door out ,by defrosting it their will be clearance between door and shelf. If it is auto defrost either one or both door hinges should be replaced

I have severe ice forming in my freezer.

Hi,

On this unit the shelves are the cooling coils and carry the refrigerant (freon) through the system. They will attract the warm moist air by design, so if you have an air leak in the door or elsewhere it will tend to build up there first.

This being said you need to check something else first. Make sure the other shelves are cold. If they are frosted and cold like normal then you most likely have a door that is not closing all the way or a bad seal. If the lower shelves are not cold then you have a system problem, typically a refrigerant (freon) leak that is causing the top shelf to absorb most of the work and not enough refrigerant to flow to the bottom shelves.

I hope this helps

Upright freezer,automatic defrost. problem: ice build-up in the bottom.

get down on the floor and look along the bottom of the door to make sure that the door seals are touching.if not and you have an air leak it will cause frost.if its ice and not frost then check all vents/drains are clear.

Ice build up

You should to check the Whirlpool Gladiator Freezerator's door sealer to make sure all rubber or plastic seal very well to prevent air humidity come in to build up frost fast. Also, you have to defrost completely and wipe with cloth or paper towel to absorb all waters out and let it dry completely to prevent frost build up.

ICE BUILDUP ON BOTTOM OF FREEZER, DRAIN HOLE FROZEN

There is normally a small filiament of metal which is attached to the defrost element and conducts heat down the drainpipe preventing ice build up. You can pour some boiling water onto this area and even wriggle a piece of plastic tubing down the drain pipe to dislodge any blockage. For future prevention, you can attach a piece of copper wire around the defrost element (in the absence of the original filiament) and extend it down the drainpiple

Fan in freezer very loud noise

There is probably an ice build up behind the plastic rear panel. The ice build up gets so thick that eventually, it obstructs the fan and then you get that loud noise as the tips of the fan are chipping away at the ice.
What you need to do is to remove the rear panel and thaw the ice build up. To remove the rear panel is usually only 2 screws at the bottom.....you will find that the panel is difficult to remove due to ice build up behind it, so gentle heat from a hairdryer is a good way to accelerate the thawing process....once the panel is removed, you will see the ice build up......mine was about 2 inches thick!!!
I used the hairdryer to thaw it all out and then once cleared, switched it back on and have never had a problem since.
By the way, my F?F is a Beko CDA563FS......the one with the water dispenser on the front and frost free.
Hope this helps

Bottom drawer wall is covered s ice/ top shelf not freezing

Sounds like a defrost system problem. Could be related to defrost timer, heaters or defrost thermostat. Have it serviced.

Fridge freezer.

I had to look up where you are from. Being the U.K. you mean 16 celsius, right? If the problem began after you removed the boxes, I don't think its a circulation problem. The ice build up on the inside, and the freezer being good but not the fridge, makes me think the defrost isn't working. I can help you check the controls for this, but without a volt/ohm meter you should call someone.
