Greetings from a fellow Floridian. As fellow Floridian, I can tell you that RV a/c is VERY likely to frost up/ice up on LOW in our humidity. You need as much air flow across the cooling coil as you can get, to get condensation out of the fins before it can freeze. If you have a good-running a/c, the cold air it discharges into the coach might be 50-60 degrees, but part of the coil could be below freezing. If frost/ice forms, it blocks air flow and also insulates that are of the coil. That makes it easier for more frost to form - it spreads! After awhile the freeze sensor finds out and shuts your compressor down, allowing time to thaw.
Your a/c could have been OK all along, or the freeze sensor could be bad or installed wrong. But even if it all good, hot humid FL summer requires HIGH FAN.
Sorry, but if the freeze sensor is installed in the CORRECT location, the Evap will NEVER ice or freeze on any part of the coil. Regardless of Humidity or Fan Speed. To The OP, Are you stating the FAN and Compressor shuts off or only the COMPRESSOR? Doug
PS, That manual takes into account mechanical controlled AC units that do not have a wall tstat. They WILL Ice/freeze in Lo fan hi humidity conditions.
