My freezer is freezing at the bottom but is not at

There is a fan in the freezer compartment that blows cold air into the refrigerator part. If it is not working or if the baffle that directs the air is not functioning, that could account for the less than ideal temps.

Also check the auto defrost mechanism for proper operation.

Make sure it's not due o excessive frost buildup.

Refrigerant charge issue

you need to reprocess your freezer to clean up the stock up oil in the tube. causing not to circulate the freon gas. you need a white line technician to fix your problem.

Check for ice on back wall if iced up check defrost heater and defrost timer also check and besure evaperator fan is working check wireharness on heater, timer, and evap. fan motor.Sounds like you have a defrost prob. Turn off for 24hrs to melt ice turn unit back on if it works for a few days then ices back up you have a defrost prob.

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.

If it has a fan in the freezer it need to be running to circulate the cold air.
If the coils are not icing up evenly from top to bottom you have a system low on freon.
The light frosting is normal.
A model number would really help to troubleshoot the problem.

I turned the fridge and freezer off using the circular dials, I then turned the unit off at the mains. Left it for a few minutes and then turned the power back on. I then turned the circular dials to "max" and then depressed the super cool and super freeze buttons to turn this facility on. This time they came on normally (not flashing) and no alarm sounded. The fridge and freezer then started to get cold. Once the unit had been running for several hours I then turned the dials to the 3/4 mark and depressed the super cool and super freeze buttons again to turn them off. Over night the fridge and the freezer appear to be working properly so I hope that my problem is solved. Maybe the unit just needed to "settle" before being switched on?

I have a Scandinova chest freezer and the left hand side froze, but not the right side, because the compressor in the box under the right side of the freezer was getting so hot, a small amount of heat was conducting back through into the right side of the freezer and preventing anything on that side from freezing!
I solved this problem by running the compressor outside of the of the freezer box, by taking the air vent off, unbolting the compressor and then pulling out by about 20cm and running it from there.

Check to see if the evaporator fan behind the freezer wall (remove wall) is running. If it isnt the air will not flow properly in the unit. Replace the fan motor and it will fix it.
