Follow-Up:
My 1996 has the same problem.I got it serviced,they checked everything twice,once by the dealer and once by a authorized repairer.They said it was working correctly.It is to small.I would like to see the the Head Man at Winnebago Sit in my rv in West TEXAS on a August Day with his suit and tie on and not sweat and say thisis how an ac is suspose to work on a 45,000.00 plus rv.Why even put it on the roof.I am now forced to look for a larger one,the old one might be big enough for my dog house.
