3 Common Causes Your Garage Door Opener Stops Working

larry Uncategorized

Ever try opening your garage door and when you press the button, nothing happens? This is a common problem among homeowners. If the simple fix– replacing batteries–does not resolve the problem, there are three other typical reasons why the device may not be functioning.

  1. Problem with the gear and sprocket assembly. In garage door openers, a motor turns the gear and drive shaft inside the opener, which rotates the sprocket attached to the top of the drive shaft. This turns the chain and moves the door. Most of the time the problem is when the ridges in the gear wear out. As a result of the worn gear, the sprocket cannot turn the chain and the door will not open or close. Problems might include stripped gears or a broken sprocket and we suggest replacing both at the same time to ensure proper operation.
  2. Faulty logic board.  Most garage door openers now have a logic board which is the “brain” of the opener. The logic board contains the radio frequency (RF) receiver for the remotes and other control components. If the remote controls don’t work or the garage door doesn’t open and close properly, the logic board might have failed.
  3. Issue with safety eyes. If your garage door isn’t closing properly, the problem could be the safety sensors located at the bottom corners of your garage door. These ensure children, pets, or others are not obstructing the safety eyes signal. The safety eyes must maintain a clear line of sight to one another. Once that line is obstructed, the broken signal tells the opener to stop closing.
