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

Craftsman garage door goes up and down but won’t stay closed using remote or button on wall of garage?
Check to see if the electric eye and reflector are not blocked and are properly lined up... the electric eye is a safety device found with most units that shoots a laser ( invisible to the eye) across the opening of the door. On the opposite side of the door frame is a round reflector which looks a lot like the reflectors found on a bike tire. The laser bounces off of that reflector and return to a sensor located on the electric eye . If this beam gets broken or is not reflecting the door will pop up.

I have a 1/2hp master mechanic door opener. when I close the door it goes the full travel down and then opens back up. i checked the eyes and everything was lined up. do you have any suggestions?
Look at the setting for "fully closed". it sounds like yours is set for slightly than the actual opening....So, the door reaches that location, and it thinks it hit an obstruction, which causes the door to open....While you are there, reset the sensitivity settings.

What I would do is back off the closed position setting so that the door stops an inch or two off of the ground, then adjust until the door is in the correct closed position...

You are correct on the "eyes" (infrared sensors) being lined up, if they were not, the door would not close at all.

SOUNDS LIKE YOUR SAFETY EYES MAY BE OUT OF ALIGNMENT OR A BAD CONNECTION.

WHEN HOLDING DOWN THE WALL BUTTON MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.


ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.

ARE THE EYES WIRED CORRECTLY?

ARE THEY AIMED AT EACH HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.


HOPE THIS HELPS

I have a craftsman garage door opener and I have to hold the button down in order to close the door. The door opens fine and the sensors are clear. The unit starts to close then stops, the lights start...
When you can close the door by holding down the wall button it IS the safety eyes or wiring.

If the eyes are mounted to the track. Many times the track wll move as the door closes causing the eyes to move out of alignment.
Watch as the door moves down and see if they need to be adjusted.

If the eyes are not both lit - they are out of alignemnt or have a wiring problem. try adjusting them and see if the lights come on. - if not check the wiring

Hope this helps

When you push either the remote or the switch at the door, the garage door will go down almost to the bottom and then come back up and the light will blink several times. This does not happen all the time....
Your safety reversing sensors must be connected and aligned correctly before the garage door opener will close. An obstruction in the path of the sensor will also cause your door to not close.
This sensor is an electronic beam, which is sent between two sending and receiving “eyes”. These eyes face each other and are located just inside your garage door. They may need to be adjusted so the beam from the sending eye is properly detected by the receiving eye. Once the receiving eye “sees” the beam from the sending eye, a green indicator light will glow on the top of the eye.

Liftmaster "Pro Line" Garage Door Won't Close-1999-#41A5021-C
If the main lights flash 10 times when the door reverses it is a problem with the door sensors or the wiring to them. Each sensor has a small light that must be lit and not blinking for them to work properly. Make sure each of them is on. If the sensors have been bumped you can tweak them a bit to get them pointed correctly. If you can't get both sensors to light then you either have bad sensors or once again the wiring is bad. I really wonder about the wiring because of the mouse problem. Also the wires are color coded. One of the is solid white and the other is white with black stripe. They can't be crossed.

If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.

Garage Door Chamberlain Power Drive 940D-01 does not move. It clicks only. It is no the spring. The light bulbs are not lighting so I think it is electric. I hear a click but it does not move. The 2 light bulbs that are inside the unit by the motor are not lit. I tested them and they should work. I believe it is related to some kind of electric. I changed the spring last week (company) and it was working fine for the past week. Thank You.
