Technology can turn out to be both a bane and a boon, and there is no better example of this than automated garage door problems. It is highly likely that in the cold and dark winter months, you will come home from work and be stranded outside- all courtesy of a malfunctioning garage door. What is more worrisome, however, is that even living in mild climates can lead to this kind of faultiness in garage doors, making the house more prone to intruders.
The easiest way to solve this issue is to troubleshoot potential problem areas and ascertain whether professional help is needed or not. Even if ultimately a technician is required, it is easier to get to the root of the problem if the malfunctioning parts have been identified. Some of the most common garage door problems are as follows:
The Door Opener Jams In the Middle Opening or Closing, or Refuses to Work Completely
All recent models of garage doors (i.e. post 1993) include a pair of sensor beams. While these were incorporated into the design for greater security, they inevitably create functionality issues. It is important to check if both beam lights are switched on, and are working properly. This is not difficult to confirm visibly since each of the beams is either red or green. If either of the lights does not switch on, it is apparent that there is a problem. Interference in function can be caused by several things- incorrect sensor alignment, the presence of a physical obstruction between the sensors, or dirt and damp on their surfaces.
The Remote Works, But the Garage Door Does Not
In this scenario, you should check the lights. If they are off, that means that the unit is not receiving any electricity. This can happen if the connection with the motor unit has been disrupted. An electrical fault may also have occurred. This can be found out by thoroughly examining the circuit breaker, fuse or ground fault circuit interrupter (GFCI).
Further examination would involve checking the emergency release chain. Pulling it will disengage the carriage and allow the door to open or shut without affecting the opener. The garage door can then be opened manually.
A Remote That Isn’t Working
This problem is obvious when the garage door opens and shuts with the use of the wall switch, but not with the remote. The remote should be checked by keeping it within range of the garage door opener, and vertically suspending the motor unit antenna. Sometimes, simply changing the batteries of the remote can do the trick. Otherwise, the remote may need to be programmed again so that it is in sync with the corresponding machinery.
It may be necessary to purchase a new remote if all of the above mentioned options do not work. In that case, care should be taken that the new remote is compatible with the garage door opener, or is a universal model.
The Door Doesn’t Close Completely or Moves Back Up After Coming In Contact With the Floor
You should immediately examine the close limit switch. In most cases, this will need adjustment. But if doing so doesn’t rectify the issue, you could try raising and lowering the garage door by hand. Often, this repetitive manual movement will solve the problem.
The Door Functions Properly, But the Opener’s Motor Continues to Run
In this scenario too, the close limit switch will need to be investigated. It should be tested by keeping it away from the motor unit.
The Door Moves Back Up Before Reaching the Floor
You should check if there is anything blocking the door’s edges. The close force of the door can also be adjusted.
The Bottom Line
A malfunctioning garage door should not be left unattended. Leaving it is dangerous if there are children about the house, or if someone is inside the garage and is unable to work the mechanism properly.
The issues listed in this article are some of the most common problems that an automated garage door owner would face. This list is however, not comprehensive. If you are unsure about where the problem originates, or whether some component is working or not, it is best not to tamper with the electrical circuits or machinery. In this case, you should certainly rely on your service provider, or the personnel who helped install the garage door in the first place.
