My RV Roof AC Does Not Cool

Question: My 87 Winnebago roof top air conditioner doesn't cool. It runs but won't get cold. What should I do?




Robbie: If the AC is 25 years old I'd be happy it lasted that long. Due to its age I would strongly suggest you replace the AC unit new. Parts will be very difficult to find. A new AC unit will be much more efficient and will save you a lot of money in electrical cost. A new AC also weighs almost 50% less that your old one. The basic rule of thumb when doing AC repairs is nothing over 10 years old, if older we recommend replacement. Have a good day and Good luck

Thanks for the Question Good Luck,
Robbie

Just say no to RVP
by: Jaime

Wow, a 25 year old roof top a/c? That is awesome! It is my understanding that RVP designs the Coleman to fail after 3 years, and mine is going that way, right on schedule. Last year I replaced the thermostat, control board and fan motor. I have replaced all of the capacitors TWICE. This summer, it seems to be blowing not as cold, so I suppose that compressor is next. If I buy another rooftop a/c it will probably be an Advent. But, honestly, this summer, I did the redneck thing and stuck a little $100 5000 BTU LG unit in the window, and all by itself it turned my RV into an icebox. It has its disadvantages, but 62 degrees in my bedroom is not really one of them. On the triple degree days, the rooftop air would still kick on, but at least I didn't have to sleep with that freight train roaring over head at night!

same problem
by: Ann

I have the same problem with my 2010 Springdale camper. My air turns on but won't cool. We had the relay box replaced and it still won't cool. Any ideas in what it could be?

My rooftop Carrier Air V will not cool at all. The fan blows in either cool or fan only modes. Is there a sensible fix? Where do I start? Would love to do this inexpensively!
