Ice forming on "ceiling" of freezer, on hinge side.

check for a bad/ loose/dirty gasket on the bottom side ofn the door. check your drainage line for clogging on the defrost system for back up

You need to replace the door gasket. It's leaking air causing the frost.

If there is frost forming at the bottom to the door, your door gasket is leaking at that location. You may be able to relax gasket back in place with hair dryer, be carefull you can melt gasket. If it is sheets of ice, your defrost drain may be frozen

If we have ice on the inside of the freezer it means air is being pulled into the box somewhere. The most likely place is the door seal, it sounds like you already checked it, but I would suggest that you look very close at the bottom and aides of the seal too, it could be leaking in air from there. Check the inside liner for cracks and seal them if you find any. Look at the corners of the cabinet to make sure there is not room for air to come in.

Air leaks will lead to frost, it is just hard sometimes to find where it is leaking in.

you probably have an air leak. if the gasket is bad it needs to be replaced. Air could also be coming in through the door flap if you have water and ice dispensor on door

If the door seals are still pliable and intact there are two possible causes.

1/ The upper door hinge on the top of freezer unit has two adjusting screws under a plastic cover/cap which allows the upper hinge to be set forward or back altering/adjusting the spacing of the door seal to the freezer body. Moving the hinge outward at the top will cause the door to seal tighter at the bottom and lessen escaping cold air and condensation to form (water droplets). Adjust carefully so as not to create a weak seal (air gap) along other sealing edges of the door frame.

2/ Many United Refrigeration Commercial Freezers are manual defrosting. Moisture from inside the freezer can condense between the inner molded door panel (door shelves) and the exterior metal door. Usually ice buildup will occur in this space, but when defrosting or during high ambient temps the ice will melt and drip out along the bottom door edge/seal. Screws alomg the door frame (hidden by the door seal) hold the seal in place and also the inner molded door panel. The inner panel can be removed to replace the seal or to remove the ice buildup.

You should check for air leaks around the door gasket or any other openings in the compartment such as where pipes or wiring is going through the wall. It sounds like a moisture problem from moisture being drawn into the compartment pass door gaskets or access holes.

pat,this is tom.if your box temps are fine.then you have a blocked defrost drain.[if temps bad ,will condensate in fresh food because warm temps]couple ways one is to shut box down eight hours other is to remove the back frezer panel and clean out all that ice and clear drain.you can use blow dry to melt ice[watch water and electricty do mix at all,be carefil]once ice gone use weed eater line with nott in one end to push threw and come out ouher end and cleanin His name,tom

your door gasket is letting in air which makes ice or frost to form ,,, the best is to replace the gasket but you may try to level your freezer with it leaning a little to the back to help it **** the door close ,,,

The reason for ice buildup is an air leak. Recheck all around the gasket by taking a dollar bill and closing the door on it and pulling it out. If you don't have resistance, you found your leak. Heat that area with a blow dryer to relax the gasket and close the door to let the magnet and seal set. Also, rub some vasoline on the hinge side gasket to keep it from dragging.
