Your garage door doesn't go down?

Updated on March 24, 2009

Are you having a problem with your garage door going down? This could be caused by several different reasons. Lets look at them all. One reason you garage door will not go down is because there may be something blocking the photo eyes mounted on the tracks of the garage door. There is two little lights (photo eyes) at the bottom of the tracks, that look at each other. This is required by law under UL 325 for safety.

If either of the lights are off this could be caused by a broom hitting the eyes while sweeping, or by a child bumping them. The fix is easy. All you have to do is re-align the eyes. One of the eyes will stay on all of the time. This is the transmitting eye. The other eye, will come on once it is lined up with the transmitting eye. I you cannot get the lights to come on, you may have gotten an electrical spike, or possibly gotten hit by lightening, and the photo eyes will need replacing.

Another reason the garage door will not go down, is because of the age of the opener. Once an opener gets some age on it, it will require an adjustment of the sensitivity. Keep in mind..just a minor adjustment. On the back of your machine wherre the wires come in, you should see an adjustment called..up force or down force. If the down force is set on the number five..turn it up to number six. DO NOT TURN IT ALL THE WAY UP TO 10!! Doing so, will make the door continue to come down, and not reverse even if the door comes down on your car, or worse, a person. Also lubricating the rollers on the door, springs, tracks that the rollers roll in, and the chain, or screw, on the opener will surely help. You should do this at least twice a year anyway.

The photo eye problems work even though you may have a Liftmaster, Craftsman, Genie, Overhead Door brand, or Marantec garage door opener. If you are experiencing a weird operation of your garage door, and think you may have gremlins in your house don't worry. Sometimes, the sun will cause your opener to not to want to go down, due to the way the sun in reflecting off of the photo eyes. This can be corrected by shielding the sun from the eyes.

I hope this helps with your garage door problems. If you have any questions, or problems drop me a line and i will try to walk you through it.

    Rob, i would replace the logic board..if the machine is over 5 or so yrs old...i would replace the machine. You can get a complete machine at Lowes for around 150.00..a logic board alone can cost anywhere from 85.00 to 105.00 depending on the model....Joe :-)

    Hi,

    I'm having intermittant issues with a Craftsman chain drive opener. The unit loses power breifly in both up and down operation. Lights blink off then back on and door stops. Pushing wall or remote resumes travel in same direction as it was going. Would you say logic board (41A5483-2B) or capicitor? There may have been a surge due other appliances needing to be replaced in the home.

    Thanks for any thoughts you may have on this, Rob
