Dometic AC Humidity

I'll start off with sorry if this is a repost and that I don't have more info, left all the paper work laying on the side table at home.

This is our first real trip in our 2011 18ft Wildwood TT. The AC is a dometic I'm assuming basic ac with 2 nobs ( one ac/fan/op heat, and one cold - colder ) no thermostat for the ac. When the compressor is kicked in and running the unit puts out good cold air and seems to relieve the humidity, as soon as the compressor kicks off and just the fan is running it is almost like instant humidity. When the compressor kicks off and just the fan is running the thermostat for the heater still reads that it is cool in the trailer. Oh yeah we are in Florida so that doesn't help any.

Is this normal or is there something wrong with our ac? Is there anyway to set it to recycle the inside air? Any suggestions on things to do?
  • It's normal during very high humidity. This is why the best residential systems have multiple fan speeds - so the compressor never shuts off.
    You could set it colder and put the fan on low so it run more.
  • Sounds normal......especially in areas of high humidity

    A/C can only affect humidity when it is running. (Compressor ON)

    And it does recycle inside air....pulls air from inside and discharges back inside.
    No outside air is used...except for air that comes in thru open windows/vents/door or around any slides
  • Sounds like your fan setting is "on" rather than auto. If so, use auto.
