Gram plus F660 L freezer

[wallwall]

Hi
I bought a Gram plus F660 L used freezer recently. The problem is that it don´t go below -9 C.
The cold side of the compressor gets full of ice. The refrigerant is R290. Both fans inside and outside are working well. ANy sugestions?

Please explain what you mean by the cold side of compressor?

Yes, true , the low side does return evaporated gasses which are cool...........but if the pipe is iced over......as previous poster has mentioned.........overcharge is likely

It´s loaded with r290 from the beginning.
Somebody has filled it before I get it! I dont´t know who it was or what he used to fill it.
Clean it and recharge

Ja that would be my sujestion as well, Vac, new Filter dryer, new oil (Why not certainly will not hurt) and a properly weighted in charge, that will have a purring away (I wuve R-290 )

have you tried DEFROSTING it?

One would tend to immagine it would defrost rather well durring transport, but non the less a good idea to duble check.
