    Light on mechanism flashing door will not shut properly
    The light on the mechanism flashes continualy and you have to hold the button on the wall down to close the door. The remote will open the door but will not close it. I've tried pushing the red button on the mech. and even tried unpluging it from the outlet but there is no change?

    inoperable light
    My touchpad has a light switch as well as a lock. The light went on when I activated the door but since I clicked the light switch to deactivate the light I haven't been able to get the light to go back on. I replaced the bulb but to no avail. Otherwise, the door opener works great.
