Refrigeration and Air Conditioning
Here is a link to something every Amel owner should read. I wish I knew how many times a person on this forum recommended adding refrigerant, or "to put in a shot of Freon" to what previously was a perfectly charged system. The reality is that the refrigerant level and/or the compressor health is almost never the cause of a cooling problem with Frigoboat or Climma systems, but it is the first thing that some owners and some technicians do. Follow this link to a great article written by the owner of Coastal Climate Control, Rob Warren.
