AC Question & I'm away!

Wanted to thank everyone for the answers. Wanted to up date you on what happened. So they tested the capacitor and it was fine. What they did find was the compressor was not working has hard as it should.Also they believed maybe a small leak. I look at the capacitor myself and it was running fine. The service company we used was Dometic rv service out of Orlando FL. They were amazing!! He installed a new 15k btu unit and they have a Carrier to Dometic adapter. So we still get to use our Carrier remote and the Carrier was 13500btu so we have a bigger unit now. Cold in the back with just the front unit now!! I have to be honest I don't have anything bad to say about Carrier lasted 15 years!! And I still have one in the bed room. The service tech said they were built like rocks and he said he never saw a 15 year old unit that looked so good. When all said and done we paid 1478.00 without tax. So we are happy and cold!! Thanks again for all the advice!
