I have a 99' 400 Sundancer. The last couple of weekends I have noticed that my Shower/Air Conditioning sump pump would cycle every now and then (which seemed unusual as I have never noticed this). After taking the top off the sump box I noticed my A/C hose going into it was wet. I check the unit under the front bunk and the pan had quite a bit of water in it and the unit itself seemed to have excessive condensation on it. I then checked the aft A/C unit and it was dry. I know that humidity is a major cause of condensation but I don't get why my forward is wet and the aft is dry. My question is: What else could be causing excessive condensation on my forward A/C unit? I should add that I have checked my vent and filters and they are all clean as well. This is my third season with the boat and I have never noticed my pump cycling unless we were taking a shower. TIA
