When my Dometic awning wouldn't close this summer, I inserted the strap in the channel, pulled my pick up near the forward part of the awning and removed 2 hex head bolts while advising DW to hold on tight to the strap. (This is all per the Dometic instructions that came with the camper).
Nothing happened. The motor was frozen. I then, standing in the back of the truck, managed to manually roll the awning in (during a lightning storm) and then braced it so it wouldn't open on the way home.
Dealer later replaced the motor under my 2nd year FR warranty.
