Hi, everyone.
As mentioned in another post, the connecting tube from my condensing unit to my evaporator is coated with ice. More specifically, the insulated sponge tubing is coated with ice and, since the temperature inside the aft cabin bilge averages around 90-100 degrees Farenheit during the day, it's dripping water down into the aft cabin bilge. Further, during the hot day, the unit will not keep the refrigerator box colder than about 50 degrees. (It keeps it in a good range during the cooler nights.)
I checked the Troubleshooting Guide in the Adler-Barbour manual, but it doesn't say anything about this problem. I also googled the problem to no avail.
Has anyone here ever had a similar problem or know why this might be happening?
My initial thought was to replace the insulating sponge tube with something thicker (i.e. a better insulator).

I have read that frosting of the tubing from the condenser to the evaporator could be indicative of too much or too little freon (I can't remember which). When the freon reaches the evaporator, that is where it is supposed to expand into a gas and start absorbing heat from the box. If the line is frosted, it may be expanding too early.
I would call Adler-Barbour to discuss this with someone personally. Good luck.

Yes, thanks, guys. I read the article. Nice. Will call Adler-Barbour as well and let you know what they say, if significant.

I simply wrapped the exposed copper tube with a swimming noodle and duct-taped around the noodle to keep it in place. This dropped the temp in the refrig 5-10 degrees. So it now stays around 35-45 degrees.
