My automatic garage door has suddenly started to open and close repeatedly when I push the close button - why?

Question

I have checked that nothing is in the way of the electronic eye and it seems to happen most often when it is quite hot outside. The door just stops while in the process of closing and then opens over and over again ... any ideas or suggestions?

Answer 1

If there isnt anything in front of the photo eyes, then it is probably

that your track needs to be greased. It seems like they all forget to

tell you about this. I had the same problem and just sprayed white

lithium grease down the track that connects to the opener....not the

tracks where the wheels are at. This took care of my problem.

Hope it helps

Answer 2

i know it sounds obvious but is the button jamming?

Answer 3

You may need to adjust the down limit.  This could be a limit switch on the track that just needs to be moved a little or an adjustment dial at the motor housing.  Check your manual for how to make this  adjustment.

The photo eyes at the bottom could be just a little out of alignment.

Answer 4

Does it constantly go up and down or just down and back up? Does it stop at the same place going down and then go back up? Make and model?

Answer 5

It sounds like you have a stuck transmitter.  Believe me when I say, that this happens a lot.  After repeatedly pushing the button over the years it starts to get worn down.  Open your transmitter, aka hand held remote, and where the button is you will most likely see a little metal piece that is sprung over a connector.  When you push that button it pushes the metal piece on to the connector opening your door, and then springs back up.  Over the years that little piece may not spring back up like it use to and even if a side is touching then it will cause the door to open.  If you bring your transmitter into a local garage door company they should be able to open it up and check it out for you. (At no charge) Good luck!

Answer 6

lets do this : release opener to manual operation open and close,  slowly try to see where door is running rough. check all hinges tighten as needed. lube rollers hinges springs etc. operate opener without door check travel to see if clear, lube rail. if door runs odd when hot,

check trim/seal around perimeter of door,lube trim with light coat of dish soap, also check the down force, and increase slightly. not the limit!
