Removing the awning from the coach is actually fairly easy, two sheet metal screws on the bottom flange once removed allow you to slide the whole awning forward to reveal the power cable and plug. I had to remove the top of the cabinet above the entry door to reveal the power cable so I could unplug it. Not sure if that can be done from the outside. I found that the motor had twisted off the drive assembly that connects to the awning roller. I did find a parts breakdown on the Dometic site, talking to a human at Dometic requires more patients than I have been able to muster, sorry for the wait and you only have nine callers ahead of you!
I may try putting a hole through the pieces and bolting them together. I was able to get the motor apart to get the broken aluminum/pot metal piece off so I now have both parts. One needs to buy the entire motor assembly if it cannot be repaired. I never use this awning so how it got energized and twisted the part off is a mystery, probably to be resolved when it happens again.
A few other items are in the queue before I can get back to the awning. Trying to hit the road in mid July to start our first trip as retired folks.
Trying to figure out all the health insurance and prescription issues takes more time than I expected. Still holding out for plan B, win the lottery, getting old enough to be in the running;>}
