Overhead door model 556 sensitivity training

awsobelJanuary 3, 2007

With the above model I have recently experienced failure of closure of the door with return to open position. I have no manuals as the unit was present when I bought my home. I have identified the LED's with buttons F+ and F-; how may I adjust these correctly to allow the door to close?

I would greatly appreciate any help.

It sounds like your door sensors could be mis-aligned. Tweak them and see if that helps. I wouldn't advise adjusting any controls until you hear from someone that is familiar with your model.

My Dad is having the same problem with his model 556 opener. Have you fixed it? What did it take?

Who makes this model 556 opener? That might help.

Looked for this opener online and could not find it. Will the opener work with the door disengaged?
