About 3 years ago,my A&E Weather Pro, patio awning, started stopping, when extending or retracting it. Sometimes it would take a dozen or more tries to get it through its cycle.
I took it to North Trail and they tapped on the forward end of the aluminum tube (that is where the motor is located) with a rubber mallet. After several attempts to open and close, while they tapped on the tube, the awning started to work perfect.
The tech said that the brakes, common to the awning motor, tend to stick from lack of use.
They called Dometic to have the motor replaced. Dometic said it shouldn't happen again and didn't need replaced. I was a bit skeptical, but the awning has worked fine for the last 3 years.
