AC has power but won't run...Help

I had to have a new roof put on my TT a few weeks ago. Of course they had to remove the AC to do the work. Yesterday I tried to turn on the AC and nothing. It is controlled by a thermostat. There is power at the AC and there is a click in the AC when the thermostat calls for AC there is a click in the unit but nothing happens, no fan no nothing. I can't find a wiring diagram to see where the wire from the thermostat connects to the AC. Does anyone have any thoughts on what I might check?

Wouldn't there be a dual capacitor for the fan and compressor that might be bad? If there's power at the A/C's contactor and nothing happens, only a click, that would mean the capacitor is shot, right? The top of the capacitor would be blown up.

Had a problem once with the fan being stuck. Just pulled down the filter and gave it a spin. Only happened the one time and never after. Hope this helps.

Suggestion, in order for them to remove the unit from the roof they had to remove the cover from the unit to get to the four bolts, you might want to get on the roof and open it up and have a look inside to see if there is anything they may have forgot to hook up, a visual inspection is the first thing to do to start trouble shooting. I posted a pic of a Dometic capacitor assemble that has burned up do to a voltage drop look for this in your unit and check it's condition. There is a good chance that the control board could be bad...Just a thought at this point.
