Most automatic doors rely on sensors to open and close. Although these devices are very convenient and reliable, sometimes your door may not function because the sensor is blocked or damaged. Here is what you need to know about troubleshooting the most common door sensor problems.
Common sensor problems
The photoelectric sensor of the residential gate works by emitting a light beam from one side of the gate to the other. If the photoelectric eye detects an object in the path of the door, the door system will no longer open or close. Your door may also start to open or close, and then suddenly reverse direction. Below are four common sensor problems that can cause these types of interference and how to solve them.
1.) Something is blocking the sensor
Branches, rocks, leaves, and other debris may enter the path of your automatic door sensor and cause your door system to malfunction. It is important to regularly remove any debris around the gate and trim large branches and shrubs to keep the passage clear. In addition, sometimes direct sunlight can interfere with the signal between the sensor beams and cause problems. If this is the case, you can use a small piece of cardboard to block some sunlight.
2.) The sensor is not aligned
The photoelectric sensor is very precise and easily misplaced. If there is no clear path between the sensors, they will not be able to detect each other and stop working. Usually, flashing red indicates that your sensor is not aligned. If this happens, simply realign the sensors manually and make sure they face each other. You can usually do this by simply tightening the screws or brackets.
3.) The sensor lens is dirty
It is common for the photo glasses on the gate to become dirty, soiled, or covered with spider webs. It is a good idea to clean them regularly. For this, you can wipe them with a dry, lint-free cloth. In addition, sometimes, water on or around optoelectronic lenses can cause them to malfunction. This is likely to happen if your sensor is exposed to rain or water from a sprinkler system. If this happens, just wait for the area to dry out before trying to open your door.
4.) There is a problem with the wiring
If the wiring is damaged, the automatic door sensor may malfunction. This can happen for many possible reasons. For example, sometimes the wires are damaged by insects nesting inside the sensor or rodents biting off the wires and weakening the connection. If this happens, you may need to replace some wiring to get your door back to normal operation.
If there is a problem with your door sensor, it is best to call a qualified door technician at. If the sensor on the door of the house is not working properly, the system may not be able to detect people, pets, vehicles and anything else entering its path, which may cause property damage or serious injury.
Door sensor replacement
Most door sensor problems can be solved by trained professionals. However, sometimes the door sensor is damaged due to daily wear and tear. If this is the case, it is best to replace the sensor completely, especially if you have used the same sensor for more than 10 years.
Some modern sensors have Wi-Fi enabled, which allows you to control the opening and closing of the gate through an app on your smartphone. If you want to take advantage of the convenience provided by the latest technology, please consider upgrading to this type of model. These sensors are very practical because they can allow contractors, friends and family to access your property even if you are not there. In fact, replacing the door sensor with a Wi-Fi-enabled door sensor may be a good investment.
