Troubleshooting garage door opener?

Posted by Sol

Admin: If it opens but does not close (should be the same whether remote or the wired switch in the garage), the problem is generally with the light sensor setup at the bottom of the door. There is often a light at the receiver end that is different (like flashes instead of staying on solid) when the beam is blocked. Watch for the change as you put your hand in front of the beam. The most common problems are something being placed in the path or one end being knocked out of alignment.

We replaced the sensors and wires because we thought that was causing the openers not to work. (The light would blink 10 times). Now when we try to open or close the door it completely turns the unit off for a minute or two and then it comes back on. I try to use the openers again and the same thing happens each time. What could be the problem?

Admin: Have you ever lubed or adjusted the door and track? adjusted the settings on the opener to close harder/ easier or higher / lower? Get the manual and do it right it is a safety issue. I do agree with the unlatch the connector and see what happens trick.
