Is the LEDs flashing on control box? Do you have the remote (FOB) box to control the awning? Have you pulled the power cable to the control box to reset the box? In my situation, the large power awning would not come out due to an error with the wind sensor...LEDS Flashing indicating an Error "unable to communicate with wind sensor" the only way to RESET the controller is with the little FOB remote. I had to buy a replacement as the original was lost. Once I got the FOB I was able to reset the awning controller, and now both awnings door and patio work great and I never use the toggle switches anymore, just the remote.
