About a year and a half ago or so my rear A/C unit quit working. I didn't worry about it too much because I had the front unit and I have a ducted system so I only really need the two units if the outside temps start approaching 100. So over the last year and a half I've removed the lower panels and upper cover and shook some wires and made sure the fan blades were free and the unit still didn't work. I figured at some point I'd take it to the shop and get it fixed.
Over the last weekend we took the motorhome out and it was HOT!. The front unit was not cooling the motorhome enough so I figured I'd look at the rear unit again. I pulled the bottom panel off and unplugged and plugged back in the wires and still nothing. Then I got to wondering if I ever checked the breaker. Of course I must have checked it, that would be the first thing any RV owner would check when something electrical goes out. So I figured I'd check it again just in case. Sure enough it was popped. Reset it and the A/C fired right up. Duh!
It may have popped for a reason, or maybe it was shut off and they restarted right away, when that is done it draws a LOT of current to over come the pressure in the system.
Good luck!
