John Dirks Jr Posted June 11, 2016 Report Share Posted June 11, 2016 In testing a garage door opener today I discovered the button needed to be held down to get the door to close. If you pushed the button and let go, the door would reverse to the opened position. I pointed this out to the owner and she said if you wait a while it will work without having to hold the button down. So I waited a while then tried and it worked as it should with one push and release of the button. The owner told me if you walk through the safety beam, you have to wait for it to work with one push. Any idea whats causing this? Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted June 11, 2016 Report Share Posted June 11, 2016 The safety sensors are not aligned - or a leaf or a spider web is blocking the beam. It's constantly trying to reverse as if an object interrupted the beam. I think waiting after crossing the beam may be an odd coincidence. It's always been quicker and easier to fix it than write it.

inspector57 Posted June 11, 2016 Report Share Posted June 11, 2016 I have had sunlight at a particular time of day cause similar issues. Rare but I have seen it more than once. Quote Link to comment Share on other sites More sharing options...
mlparham Posted June 11, 2016 Report Share Posted June 11, 2016 I have had sunlight at a particular time of day cause similar issues. Rare but I have seen it more than once. When you have sunlight interrupting the beam try installing an empty toilet paper roll over both beams. It shields the beams from the sunlight and works very well.

Tom Raymond Posted June 11, 2016 Report Share Posted June 11, 2016 If misaligned eyes work occasionally than they or the logic circuit are broken. If parts and service are half the price of a new opener replace it. Quote Link to comment Share on other sites More sharing options...
mjr6550 Posted June 12, 2016 Report Share Posted June 12, 2016 The sensors may be almost aligned so that they work intermittently. Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted June 12, 2016 Author Report Share Posted June 12, 2016 Whenever the door closer does not work right I check the beams for obstructions and there was nothing. They did not appear to be bent out of alignment. Sun was shining in on them so maybe that was it. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted June 12, 2016 Report Share Posted June 12, 2016 What brand opener? I know that Liftmaster has tweaked their safety features lately. Quote Link to comment Share on other sites More sharing options...

Nolan Kienitz Posted June 12, 2016 Report Share Posted June 12, 2016 The sensors can also just totally fail. Mine did recently and I just had a new unit installed. The old unit was about ten years old and getting noisier and noisier. My maintenance routine was not working to smooth out it's noisy and jerky operation. The new operator units sends me text messages when it opens/closes. It is very quiet and simply is close to impossible to hear from inside the home when it opens/closes.
