When I try to close my garage door by using either the remote or the wall button the door will not close, I get a flashing of the 2 lights at the garage opener for 10 seconds. The only way I can get the door to close is to hole the wall button until the door closes. I need help on this one. Can it be the censers are off as you enter the garage that are near the floor of the garage door.
Thanks
