 | Garage door problem I have a Craftsman 1/2 HP garage door motor.
Today, the garage door would not close with when I press the garage door button. It moves for a few inches and then goes back up, clicking sound is heard a few times.
I disconnected the garage door from the track and it opens and closes just fine - without the load of the door.
I opened the door again with the door button, disconnected it from the track and hit the garage door button. I dont know what that thingy called but it moved ok.
Apparently, the door works when I try to open the door but does not work when I try to close it.
The photo eyes are aligned.
The light at the back of the motor blinks 4 times. Does any one know what that means?
Thanks |

 LazManPremium join:2003-03-26 canada | Your 'close force' is pretty much at minimum - I'd try dialling it up a bit.
I had a similar problem with my father-in-laws door; it would close about 6" then reverse... Near as I could tell, there was nothing wrong; the rolling resistance of the door was just right at the threshold the opener was set to, and over time, got slightly harder to close (bearing or spring wear) and was tripping the safety... I turned it up a bit, and it started behaving normally again. |

One or both sensors should have a light on them indicating whether they detect an issue. Brush off any dust from the eyes and try again. |

| reply to iLearn Mine does this in the evening at sunset. The sun shines at just the right angle to mess up the photo eye. It's a Crapsman 1/2 HP too. It's very annoying when it stops and does the stupid "clicky-clicky-clicky-clicky" routine.
If you hold the hardwired button down, it forces it to close. -- If someone refers to herself / himself as a "guru", they probably aren't. |

 | reply to iLearn Thanks All.
LazMan - I will try it in the morning. May be it was the sun light as nunya said. If it does not work then I will try to increase the 'close force' by one notch.
psafux - There is nothing obstructing the eyes. I tried to clean them up and both lights for the sender and the receiver are lit. So I dont think that is the issue.
nunya - Crapsman lol. Sorry but what is the hardwired button and where it is located?
BTW, I did put WD40 all over the assembly and everywhere in an attempt to reduce the noise down during operation. Later I found out that it was not a good idea to do it. It was not me guys, it was a buddy of mine who suggested this to me. And guess what, I called him up when this happened and he is also having some type of problem with his door. And we both put WD40 on our door around the same time.
I wonder if this has to do anything with this.
I will find out more about his and will keep you posted. |

 mityfowlPremium join:2000-11-06 Dallas, TX | reply to iLearn The next time you lubricate. Use lithium grease not wd 40.
Also it would behove you to put some oil (not wd40) on your spring. |

If it was cheaper than lithium grease or about the same I'm sure I would use it.
Maybe not on top of the grease thats there though. |

Over time dust and whatnot will accumulate and gum up the tracks. -- ~Help Find a Cure for Cancer~ ~Proud Member of Team Discovery ~ |

| reply to iLearn My guess is that from what you are describing it is a down force issue. If it's moving, even just a little bit, then the eyes are probably clear. For a test, you should block the eyes and verify that the indicator on at least one of them is not lit up. Try putting the door down. It should instantly click and blink with no door movement.
Increasing the force required to auto-stop the door from closing will very likely fix your problem. What I'd do is take a look at what it's set at now, make a note of it and then crank it up to maximum. Try putting down the door. If it works fine, then that indeed is your problem. Reset the force to one level higher than what it was originally set at and try again. Keep bumping it up one level until the issue is fixed.
EDIT: Yeah, this has happened to me with the same model of door opener. I verified the opening chain (now belt) and tracks were in proper operating condition (as it sounds like you've done) and a slight bump-up in force close took care of my problem. |

 | reply to iLearn oh wow.
I just tried the garage door several times and it worked fine.
So was it not working because of the nunya's sun light theory? I did not change any settings. damn. 
But I have lived in this house for 3 years and was it just the coincidence that I never operated that door exactly at the time when sun is shining at the eyes? who knows?
If it happens again then I will play with the force setting as others suggested. |

| I have nunya's sun problem sometimes during the year. I solved the problem by taking some cardboard and making a sleeve to shade the lens of the sensor from the sun. Not particularly elegant, but it beats the heck out of trying to rotate the house 30 to 45 degrees. |

 | I did the same cardboard trick. I still have the problem sometimes during the year. I may have addressed it once by swapping the two sensors. I think one transmits and one receives. -- nohup rm -fr /& |

Perfectly aligned system will not be bothered at all by the sun ... unless you have a glass wall or a huge hole right behind the transmitter. The simple reason is that the receiver-to-sun straight line will be at least 15 degrees away from the receiver-to-transmitter straight line for a proper garage door setup.
It is possible that the aiming was off by a few degrees during install but still allowed the transmitter beam to fall on the receiver lens with sufficient intensity. However, the bad aiming also allowed the sun to fall on the lens. |

It may be just a nuisance to most people but home/personal security could be compromised on rare occasions. Since you have the most experience with this problem, please record a demonstration video during the next sunset and kindly upload it.
It is possible that some receivers were assembled with a wide angle lens by mistake. The receiver's acceptance angle can be easily checked. |
