Garage Door Opener
Garage Door Openers Common Problems:
1. Door Goes Down All the Way, Then Opens Again
If this happens, the most likely culprit are the open and close limit settings of your garage door opener. This range tells the garage door opener how far the door should move before it is fully closed. If your settings are too high, the door will hit the ground before the opener thinks it should and assume the door is hitting something in its path. It will then automatically reverse to prevent crushing it. Check your operator’s manual for how to set the open and close limits.
Every garage door opener comes with a disconnect switch in case the power fails to allow you to open or close the door manually. This switch is usually attached to a rope or knob that can be accidentally unhooked. Close or open the door all the way and then reattached this hook secure. Then try opening or closing the door again with your transmitter.
3. Automatic Garage Door Opener Runs for a Few Seconds then Turns Off but Door Doesn’t Move
This normally happens when the door is closed and the motor is trying to lift the door and it won’t move. First check the springs ... and if that isn’t the problem check the track for obstacles. If neither of these issues exists, check to make sure your garage door doesn’t have a built in lock that has been engaged directly. These are very common in older doors and can be easily engaged by accident.
