Hi thanks for the question.
Is this a frost free freezer does it have a freezer fan motor.
Okay I went back out and checked them again and they are all cold.
I see , thanks for the pictures, now I know what you have, if both those cols are cold ,
real cold so your fingers get stuck to the coils then the compressor is ok, but if there not that cold then the compressor is not working at 100 % . and you said that theres was frost on the top shelf and not the bottom one.and thats a compressor problem.
