The AC is back in operation, for now. The latest failure was in a small electrical component labeled "motor starter". This thing is the size of a larger postage stamp and about a 1/4" thick with two wire connectors. It was rather "crispy".
While there, the tech did some extensive diagnostic tests and found the compressor was drawing more than it's rated amperage for the temperature. It was 75 degrees outside and the compressor was drawing the maximum number of amps for a 95 degree temperature. The tech wanted to swap out the unit figuring the compressor will fail fairly soon. Dometic refused even though the unit is beyond their own factory specs. I expect to have to deal with this again before too long.
If you get a moderate to strong hot electrical smell while running your AC unit be prepared to call for service. Chances are it may be either the large capacitor or the starter motor device. If it's the capacitor is does burn wires attatched to it.
