A couple years ago mine "ate" up the wiring the double sided taped to the arms.
I had to manually extend the awning. If I recall correctly the motor needed to be removed. Make sure you secure the awning with bungee cords or something as once the motor is out it will extend all the way quickly. I thought that was all in the manual. Or it is possible I had support from Carefree directly from their phone.
I don't make it much on here anymore so will not see your reply to my comment. Drop me a direct message and when I come back on I will see it.
