Just started doing it yesterday while I extended them to get width measurements for a new garage in the spring. All four went out fine, but when trying to bring them back in, the breaker tripped almost right away. I reset it and tried again and the did the same thing. So after that I reset the breaker and did them one by one to see which was doing it and it is the front curbside one.
Any collective ideas on where to start looking? They are Zip Dee awnings FWIW. They do not make funny noises or anything and when they went out the front and back traveled at the same speed and worked normally.
