My frigidaire its a side by side 2006 and it he freezer wont freeze and the fridge not cold enough..
Took it apart and the compresor is working
The condenser is clean and the fan is running
The evaporator fan inside the freezeris working
Now on the evaporator inside the freezer its all frosty looking on the top only
Would that be why he fridge is not freezing or thats normal
He seal around the fridge is good

Please help

Sounds like a sealed system problem (low freon).

Below is a link, take a look at the example pictures about half way down the page.

Be sure that the compressor has run for at least a couple hours.
If you do this test during or shortly after a defrost cycle (compressor and fans will be off during defrost), you may come to the wrong conclusion.

A sealed system problem will be an expensive repair as you need a pro.
Also there is no use adding freon until the leak is found and repaired.
Finding it is not always possible.

In many cases it makes more sense to put those dollars towards a new unit.
