An Electric Short In The System

The most common reason for the garage door open itself could be because of a damaged circuit board, which helps the entire garage door to operate. It is also known as a logic board that has a circuit inside wired in a specific manner. In some cases, due to the damaged circuit, the door does not function appropriately. Therefore, a Proper Garage Door Tune-Up by a professional should be done annually to save yourself from spending hundreds of dollars on repair.

You Have A Bad Wall Button

How To Fix A Garage Door Opening By Itself | Clear Garage Door Codes

Because most wall buttons have integrated circuit boards, they can intermittently trigger your garage door to activate. Even your basic doorbell style buttons include small circuit boards behind the plastic housing. Even though a wall button circuit board could be intermittent, its not the most common issue we encounter.

As a wall button is used over time, the button will start to wear down. As you press this button, you will notice it jiggles or has a lot more play than it did when it was new. The worn out button can accidentally activate your automatic opener when someone closes the walk through door going from the garage into the home.

I know this may be hard to believe, but we have seen occasionally where the deep soul rattling bass from a large V-8 motor or Harley-Davidson motorcycle was powerful enough to cause a worn wall button to activate. I didnt believe it at first either, but after witnessing it at a customers home, it was true. You learn something new every day.

Have Your Door Serviced

An automatic opener, just like other mechanical devices, needs regular servicing to keep it in good working order. Dust it thoroughly and wipe down the chains and sensors to ensure they can receive a clear signal.

In addition to the opener, other parts of a garage door require maintenance as well. Springs, hinges and rails need regular dusting and oiling to prevent seizing.

If you want to adjust the sensitivity of the garage door opener to prevent accidental opening and closing, you can do this yourself by following the instructions in the owners manual.

Multimeter Vom Opener Wiring Testing

Again, you can check for a short in the wiring with a multimeter. The location you are measuring factors in to if your wiring has a short. If you are checking both ends of the same wire with 0 resistance then current is flowing through the wire. If you are testing the ends of two different wires with 0 resistance reading, that means both wires are connected. Are they supposed to be connected? If not, that indicates a short.

If the screen shows that its open, then youve got trouble. If you want to truly fix this problem, youll need to track down the obstruction thats keeping your door from closing.

  • Look at the circuit board. This is an area that you do not want to work on yourself. If something seems odd or wrong when you look at the board, call a local garage door repair company.
  • Reset the codes. If you have an older garage door system, it can help to reset the codes. Unplug the remote control component on the unit and plug it back in. If this doesnt work, try switching the breaker off and back on.

    Frozen Door Snow And Ice Buildup

    Garage doors are usually made up of 4 or 5 sections. During snowstorms and excessively cold temperatures ice can build up between the joints of the sections. The groove of the door joint can get filled with snow and ice causing the tongue section to get blocked. This is especially true as water drips off the rooftop and runs down the face of the door it hits the top tongue and groove joint first.

    Safety SensorsIf you close the garage door, but it comes back up at some point before completely closing, the safety sensor might be the problem. If nothing is in the path of the sensors lenses, make sure they are clean and properly aligned. Sometimes dirt on the lens, a slight misalignment, or a loose sensor bracket can cause the sensor to believe something has broken the sensors beam. Make sure everything is tight, lined up and clean.

    Sensor WiringIf that doesnt solve the problem, it could be the wiring between the sensors and the opener. Power down the opener and make sure the wires are connected securely, and there is no exposed wire that could come into contact with other objects.

    Be sure to consult your product documentation before attempting to repair your opener. If youre not able to determine the cause of the phantom operation you might want to contact an overhead door expert to troubleshoot the problem.
