Gram plus F660 L freezer
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?

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

Itīs loaded with r290 from the beginning.
