My experience: put the awning out. When it was time to retract it that night it would not roll in. Between skeeters and dark tackled it the next day. Tried the over rides etc etc. nothing worked. Power at switch, power at motor but no workie. Deduced it must be the motor. Took things apart and found that one of the brushes was not making contact with the armature simply because the wire was hung up not allowing the brush free movement in the race. Freed it, reassembled and zero problems in two years.
