Hello people. I have a refrigerator that works with r600a and the problem is that above it cools and not below. It is a refrigerator with freezer (not nofrost) It is the first time that I grab a job with this refrigerant and I would need advice. I already know how to charge that refrigerant (liquid or gas) when you finish loading the refrigerator as I do to weld the extrangulation of the service pipe since it is flammable. Any information would appreciate it

Hi . If you put a valve in the compressor sevice appendix you just have to strangle it with a clamp and then weld or just leave the access valve that you are going to weld and you don't have to worry about welding
