Top of freezer freezes but bottom doesn't - GE 20.3 cu. ft. / 575 liter Upright Freezer FUF20DPRWH

you may have ab ad fan inside the cooler and all of the cold air is staying at the bottom. Also there may be bad insulation at the top and there may be warm air up there.

Just had this issue. Freezer is packed usually & suspected airflow. Emptied bottom 2 shelves & vent strip was solid frost. Bottom 2 shelves were filled w/ solid roasts & other solid large items. Used blowdryer & currently waiting to see if it begins freezing top shelf.

is the top of the freezer full where it can breathe remove something to help it breathe

There is a fan behind the back wall of the freezer about 1/2 way up from the bottom, you should be able to hear this running when the freezer is on. If you do not hear this then you need a new evaporator fan motor.

If you hear the fan run then you most likely have a problem with the automatic defrost cycle that would most likely be the heat element that is located just below the coils inside the freezer behind the panel.

Is your circulating fan working?
Sometimes they stick and need a shot of WD 40 and then work
it back and forth a little until it wants to take off again. Keep me informed
and PLEASE give a Thumbs Up for the effort. The Raz Shack

Sounds like a circulation problem. Does it have a fan inside the freezer. Should be bdhind the floor or one of the wall panels. There should be a vent for the air to circulat through. If so check to make sure it's running when the compressor runs.

Short on refrigerant would be a good starting point, pressure temp relationship should be tested by an opperative.

YOUR EVAPERATOR FAN IS STUCK OR BURNED OUT,REMOVE BOTTOM PANEL AND SEE IF BLADE IS STUCK,TRY TO RUN START IT WITH YOUR FINGER,IF IT WILL NOT START REPLACE,THANKS-MIKE

someone suggested to me the other day to put weter foods closer to the top the ones with dripin water and more solids down at bottom they said this changes the climate inside to be more economical
im just passing this info cause ive never had or been in contact with a upright freezer

when you plug it in do you ear a fan running if not plug the freezer on.and at the bottom of the freezer gently hit were you have a grill sometime the fan motor gonna start running and circulate the cool air if it work keep and eye on it for a few days take care cheers
