The external wires work if the control box fails, but don't help if the motor is the problem. In that case, you remove the cover (maybe 5 screws), then unbolt the gear assembly (2 or 3 bolts), roll up the awning by hand (one person on each end on a ladder), then reinstall the gear assembly to keep the awning from unrolling. If the motor fails when retracted, like mine did, you can't remove the cover except by destroying it.
