Weatherpro awning that has your symptoms indicates a bad motor. It is tripping the excess amp control. To manually retract, you disconnect the motor wire plug from the controller and apply 12 volts to the 2 wires. If the controller is not easy to find, you can also disconnect the quick connect at the motor and jump the 2 motor wires with a 12 volt battery. I use a 12 volt Computer battery back up(UPS) battery to do this. Doug
PS, there are 2 motors the Weatherpro uses. Depends on if you have the intergrated roll down patio screen as part of the awning assbly. Roll out the awning and get the Model/Spec/serial number before it finally fails.
