Thanks for your reply. The divider between the two was not air tight, so I taped it up. I did notice that where the freon line comes in through the foam housing there was daylight and the supply coil was a little dirty. I plugged the hole and cleaned off the dirt. After this and a few other things I decided to go ahead and replace the unit and the new unit cools much better, however, the original unit that is cooling works better than the new one...the air coming out of it is around 50 degrees and the new one is about 55 degrees. Thanks again!

Thanks for your reply. 4 years is the age of this unit. The temp difference was about 8 degrees. I cleaned the coils and taped up the divider between return and supply. I did notice that where the freon line comes in through the foam housing there was daylight and the supply coil was a little dirty. I plugged the hole and cleaned off the dirt. I tried again and the temp difference was about 12 degrees. I pulled the hood off the unit that was cooling well and compared the line running to the inside coil and there was significant difference...it was cold and covered with condensation. The unit not cooling was dry and only slightly cool. I decided to go ahead and replace the unit and the new unit cools much better, however, the original unit that is cooling works better than the new one...the air coming out of it is around 50 degrees and the new one is about 55 degrees. Thanks again!

Thanks for the reply and the manual. It is different from the one I have. The unit is on a trailer built in 2017.

Thanks for the suggestions. The units did get a little hail damage so I have spent a few hours up there with a fin comb. Best I can tell, everything between supply and return is sealed up and the coils are clean. I will pick up a couple of thermometers to check the difference in temp. I did find in the online manual that the compressors are rated at 13.2 amps, so the one not cooling is a bit low. Thanks again!

I have 2 Dometic Brisk II 15000 btu ACs B59516 on my (new to me) travel trailer. One does not seem to be cooling that well. On a 95+ degree day the compressor was pulling from 11.75 - 12 amps and the air just seemed slightly cold, however the unit on top did have a small stream of condensation coming out of it. The other unit at the same time was pulling 13.25 - 13.5 amps and was cooling very well. The air coming out of it was noticably colder. The unit pulling 11.75 amps has clean coils and everything else seems to be working on it, just is not cooling well. If anyone familiar with what these compressors should pull in amps, please reply and let me know what the compressors (blue wire) should be drawing in amps when running on high cool on a hot day. Also, please advise if I need to replace the one not cooling that well, based on amp draw. Thanks.
