This should be an easy fix....if it's what I think it is. You have to get up on the roof and remove the A/C shroud. There are a bunch or #2 Phillips screws holding it on around the base. Then you need a 5/8" nut driver to remove the control panel cover located on the right side of the unit. (If it's a new unit from Dometic, it might be the new plastic snap-in type). Located just in front of the circuit board, you will see two capacitors, one large and one small. It is the smaller one that you are interested in.
This is the start capacitor for the fan motor and should have a PTCR (positive temperature co-efficient relay) snapped on top. It is the PTCR that usually burns out, taking the attached capacitor and wires with it. A 'hard start kit' is available from your local RV supply store (or from me, as I stock these things). Don't remove it until you have the new one so you can match up where the 2 wires go (it's not hard to do, but you won't know what goes where if you have never done it before).
Also, If your unit is less than 2 years old, it should be a warranty item and if you mess with it neither Dometic nor Airstream will cover it AND will probably void your warranty!!
Better call your dealer or A/S first before you even go into the unit to look!
