Our 4830 freezes the evaporator up on hot humid days. Goes from being cold in the cab to not cool enough. Try turning the a/c off for five minutes or more ( but not the fan) let it melt, turn the a/c switch back on and see if it is good and cold for awhile again. Easiest way to tell that it freezes up.
