Why Garage Door Opener Is Not Working


Assume that you are getting ready to attend a wedding ceremony. You and your family members are well dressed. You make sure that you close the door of the house properly and proceed to the garage to start the car. You press the remote of the garage door and start the car. The car has started but you still wait for the garage door to open. You keep pressing the remote but the garage door doesn’t open. What will happen next? The entire day gets spoilt. Many would have come across such a situation. What is wrong with my garage door would be the question? It could be one of many reasons like a weaker battery or your entire system has become faulty.

It may be a simple repair that one could do it themselves or may be a complicated one which needs an assistance of the professionals.

Unplugged Garage Door

It may sometimes happen without our knowledge that the garage door is not being plugged into the working outlet. In such a case plug in the wire properly and try it again. There may also be a certain situation where the outlets or circuit gets fused. In such case, plug in some other electrical device into the circuit and try whether the circuit is working properly.

Old Batteries

For a garage door to be opened, one of the transmitters has to be mounted on the wall and the other has to be in the car. If you have a couple of remotes, then try to open the door using both the remotes. If one does not work and the other works, then it is probably time to change the batteries in the remote.

If both the remote seems not helping to open the door, then check by pressing the button on the transmitter mounted on the wall directly. If directly pressing the button opens the garage door, then the battery of the transmitter on the wall has to be changed.

Blocked Photo-eye

Photo-eye is a device that had been used in garage doors for the past 20 years. If the laser emitted by the photo eye is blocked or in other words, if it is not received by the other end of the door, then the door will not raise automatically.  Check whether the photo eye is blocked or damaged by any means. A recent rain or dust might have blocked it. So clean it with a neat tissue paper or a plain cloth and test opening or closing the garage again.

 Misaligned photo eye

If the photo eye is clean, then you have to check the alignment of the photo eye. The photo eye must point in the same direction and at the same angle. If they are not same, one would assume that the other does not exist and the door remains closed. It may also happen that the sensitivity of the photo eye is too low or too high which stops from closing the door properly. Hence try to adjust the sensitivity level properly.
