When your garage door won’t open all the way, it can quickly become a real inconvenience. There are several reasons why your garage door won’t open completely. Before calling in a professional, learning to troubleshoot your garage door issues can help you solve the problem. Here are some of the most common reasons why your garage won’t open fully. Dirty or Blocked Photo Eye The photo eye is a small laser beam near the at the lower end of your door frame. It is a safety feature used to detect objects so the door will not close if on someone. If the photo eye is blocked or dirty, your garage door won’t open or close properly. Worn wires, twigs, debris, or other dirt can get block the eye preventing the laser beam from detecting objects in the entranceway. Cleaning the eye and replacing damaged wires will fix the problem. Power Source Disruptions A disrupted power source is another reason why your garage door only opens halfway. The overhead door uses a motor to open and close. The motor is activated by a automatic door opener. If there is a disruption to the power, this could prevent the liftmaster from opening. Check the circuit and electrical outlet in your garage to make sure the overhead door is getting power. Travel and Force Limits Need Adjustment The travel and force limits are built-in safety features that tell the overhead door system how far the door should travel on the tracks to open. If the alignment is off, your garage door will not open all the way. Consult with your manual on how to fix your garage door not opening or call a professional technician to realign your travel and force limits. Cables are Broken or Disengaged If the cables are broken or disengaged from the track, your linemaster garage door will not open. For safety reasons, any repairs to the cables should only be done by a qualified garage door installation technician. Broken Torsion Springs The torsion springs work with the cables to open and close your overhead door. If the torsion spring is broken, your electric garage door won’t open. Because the torsion spring is made of a strong metal like steel, titanium, beryllium copper, or carbon steel and are very tightly wound, it is dangerous to replace yourself. If your garage door won’t open fully because of a broken torsion spring, contact your local garage door installation company to fix. Door Opener Not Working Sometimes garage doors only open part way because the garage door opener in not working. If this is the reason, check the opener’s antennae to make sure it is not broken, replace the battery, and if your garage door still does not open fully, reprogram the opener.
