Door won't go down
Yes ,your path may be clear and you might have two indicator lights lit,but remember that theese sensors are called a sender and a reciever,the sender send,s a signal to the reciever to let it know that alls clear and their are no obsructions , but i can tell you from experience that if your sensor has the slightest fliker it will not allow the door to come down as a safety feature that was incorporated in all machines by law from 13 years ago, First thing you want to do is find out which sensor is the reciever and this is very easy ,Just put your hand in front of one of the camera,s ....The one sensor that,s light goes out is the receiver, Thats because it is not receiving a signal ! Now I want you to make shure it is straight in it,s holder,aiming directly accross from the other sensor! Next go to the sender ,This beam is the crucial one and must be directly pointed at the reciever, notice the light on the sensor it is always solid and will not go out ,Next i want you to go back to the reciever and loosen up the wingnut that holds the sensor in the bracket , as you move the sensor up to down and left to right notice the light on the receiver become dim and bright and flicker as you move it from the direct path of the sender , this is exactly what i want you to adjust to it,s brightest light possible , after you have tightened it back up go over to the wallpad or doorbell that operates the door and see if your problem has now dissapeared , Thank you for letting me try to help you and hopefully we fixed together Sincerely Glenn Mayer
