We have a 15K BTU Coleman Mack a/c on our TT. Before the end of the first season, condensate began (not rainwater) began to leak inside the TT. So we had the a/c replaced under warranty. It was not long after the replacement that the new a/c began to leak again. After two years of leaking condensate water into a bucket, I finally found time to troubleshoot the problem. Thanks to this site I found the procedure to pull the shroud, clean the coils and clean the ONE weep hole.
That's right ONE tiny little weep hole. And that one tiny weep hole is sandwiched between the bottom of the a/c and the roof of the TT. Am I the only one who is astounded by this? How is this design not causing problems for everybody? I am also shocked the dealer would bear the expense of replacing an a/c when cleaning a weep hole is the solution.
Anyway, during my contemplation of how stupid this design is, I drilled a decent size hole in the side of my drip pan to ensure a steady reliable drainage of condesate that is easy to access and clean. You may jump all over me for doing it. But I dont care. Flame away.
