Hi
I bought a Gram plus F660 L used freezer recently. The problem is that it donīt 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

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