Hey guys, I'm sure these questions have been asked before, but please humor me. I have a Dometic B75915.711c0 13,500 BTU A/C unit. It's not cooling. I popped the cover off and the compressor is running, the high side is hot, but the low side is ambient temperature and the evaporator is luke warm. I assume it's low on refrigerant since the electrics seem to be working fine. I see no ports to charge the system, am I to assume that if this system loses its charge I need to replace the entire unit? Is this the industry accepted repair? I ask because I have a warranty on the trailer, and I can make the repairs at my shop, but it's a car dealer so we're not familiar with all things RV. I'm going away late next week, Amazon shows this exact unit for a replacement, if I order it today I can have it Tuesday and I'd install it Wednesday, and I'll be good for my trip (DW will NOT go without a/c). I like the thought of getting the same unit for ease of installation. I want to make sure that this is the right thing to do, because I have to order it today, before I get approval from the warranty company. Thanks for the input guys!
