John Keith Does the sensor that reverses the door when something breaks the light beam have something blocking the light beam so the opener thinks there is a kidlett or animal under the door. If it closes by your holding the button, does it open ok. If so, it is almost surely the safety detector that wa misaimed when someone bumped inot it. Bob Hofmann |

- this problem does not occur early morning or early evening The light sensors are dirty. Wipe them clean. |

John Keith Symptoms you describe indicates a "safety system reversing". here is the key one..... - if the wall button is held continuously the door will close completely The GDO "thinks" something is in the way. Force adjustment is not the solution. Make sure the electric eye system is clean & pointed correctly, red (or green) lights on top of electric eye housings should be continuously lit. cheers Bob |

wrote in message ... - this problem does not occur early morning or early evening The light sensors are dirty. Wipe them clean. Monitor the sensors while you try to close the door. Mine were showing a steady green light until the motion of the door caused them to move just enough to break the circuit. A simple adjustment and making sure the bolts were tight is all it took.

I was able to look at the door again today. I cleaned the lenses and
checked the alignment. I was able to verify the green LED was working at one sensor and I think the other sensor is yellow. But in any case the door did cycle correctly once for me before I had to leave. I'll see what results the owner has over the next few days. John Keith |
