Re: not all the shelves are getting cold
All the shelfs should be getting cold starting at the top and working down. It may have a leak in the system or a restiction not letting the freon flow. It could of had the problem before the defrost. Small enough problem to stay frozen but won't bring back down to temp. Check to see if it's still in a sealed system warranty if so call for service.

I understand that you are having trouble with the door sealing properly on your Frigidaire freezer, model# FFU17C3AW1. I see that you have already checked to make sure there is nothing blocking the door from closing as well as making sure there was nothing between the door gasket and the freezer body. Next, I would check to make sure that the gasket is not damaged or compromised in any way. If it is not damaged, I suggest contacting your local authorized technician for further assistance. They will be able to diagnose your freezer and determine what is causing your appliance to properly seal. Hope this is helpful.
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.
the defrost circuit has a problem, allowing the frost/ice buildup.. remove the shelves, and back lower cover in the rear of the freezer to expose the evaporator coil, defrost heater, and defrost thermostat. the defost heater should have continuity through it and the defrost thermostat will have continuity when frozen but test open when warmed.. if either bad replace. if both test good look for bad connections in the freezer compartment wiring, and moly connectors otherwise the temperature controls are bad and it is an electronic assembly that incorporates the temperature controls with the deforst timer controls.. hope this helps, best of luck, ttfn
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.
If this is the type of freezer where the shelves are the evaporator coils, the coolant goes through the shelves(tubing) and the formation of frost is normal and has to be manually defrosted.All the shelves should be as cold asd the top one. The fact that just one has any frost may indicate that it is low on freon. If this is the case you should notice that the freezer doesn't get cold enought.
That is normal. The refrigerant runs through those shelves. They are the evaporator side of the unit.That is where the freezing effect comes from.
Check door seals for leaking air.
Keep door openings to a minimum.
Get in there and get out.
Those things will help prolong frost/ice buildup.
