Garage doors are a great investment; however, like many investments, there may be a few hiccups that you need to get sorted out. Previously, we started a troubleshooting guide that can help you out when your garage door is acting up. So, what if your garage door is opening and closing by itself?

My garage door is opening and closing on its own, as if someone else has the same frequency transmitter.

In many of these cases, when a garage door starts opening and closing by itself, or if you find your garage door open upon returning home, the problem is due to a short somewhere in the garage door system. This short is usually in one of two places: in one of your transmitters or in the wall button’s wiring.

If there is a short in your garage door transmitter, you’ll often return home with your garage door open, even though you know for a fact that you had closed the door before leaving for the day. What happens is that a short in your transmitter can cause a signal to be present. As you’re leaving your home, watching the garage door close fully and appear to stop, the carriage and arm run past the down limit therefore reversing the door and opening it again. One of the best ways to troubleshoot this problem is by removing the batteries from the garage door transmitter and then operating the door from the wall button. If there is an intermittent problem, the transmitter may be the culprit, or the other way around.

If this problem persists, try removing the wall button wire at the unit’s motor head to ensure there is no short in the wire that runs to the button; then try operating the garage door with only the transmitter. If the problem stops, you may have your answer! The reality is that this is a process of elimination. Get all the garage door help you need in Torrance by giving us a call today!
