Once the snow settles down, I'll go check the capacitors (excluding the start capactors).
I have a friend who is an HAVC guy - but in order to test it, i'll have to pull the unit from the trailer and take it up to his house (it's an hour away) to see what's going on with it.
Can you check the wiring on the compressor to determine if it's toast? for example, on some of the motors, you can check the resistance of the stator and if the resistance is more than 'x' then you know it's done.
Of course, if it's done, then I can look for a more efficient unit that uses less current. I know there's some "high efficiency" units that are being made now - so that may be something to investigate.
