This is normally only an issue on newly installed doors, but occasionally this limit may need to be adjusted.

If this is set incorrectly, the door may hit the ground and immediately bounce back up because it thinks there is something in the path. Garage doors have a limit range that let’s the opener know how far the door should move before it’s fully opened/closed. You can pul the rope towards the door to re-engage the trolley. The door would only open manually in this state. If the rope on this devices is pulled, it can bypass the opener, which would prevent the opener remote or wall unit from opening the door. The latch/pulley system (usually has a rope hanging from it) that connects the garage door to the opener is called the trolley. The door could close unexpectedly, and even fall from the track if there is significant damage. You may be able to clear obstructions or straighten the track to get things moving again.īe very careful if you attempt to remove items or manipulate the track in any way. Make sure there’s no visible damage or misalignment. If the track is blocked, warped, or if it has been bent or damaged, your door may not close.Ĭheck the track to make sure nothing is preventing the rollers from moving. Occasionally the track that guides your garage door up and down can have an issue. You can purchase or fashion your own sun shades to reduce the lighting hitting the sensor lens if this happens. A dirty sensor can also cause errors.Īlso note, especially if you have issue only at certain times of the day, it’s possible the sun or other reflections are hitting the sensor lens, tricking it into opening the door. Make sure there are no streaks after cleaning. These sensors often need to be cleaned also. Some sensors have a light that will blink or change color if they are misaligned. If they appear misaligned, there’s a wingnut on each sensor you can loosen/tighten by hand to make the necessary adjustments. The lenses on each sensor should be pointed directly at each other. If the sensor isn’t blocked, check the alignment. Any object between the sensors while closing will cause the door to reverse direction. If your door starts to close, but doesn’t go all the way down, this could be the issue.

These safety sensors prevent the door from closing if something is in the path of the door. Your sensors are typically mounted just inside the garage door, near the ground, on both sides of the door opening.
