The sensor is a safety feature on most doors to the garage. It minimizes the risk of a pet, a car, or a human getting hurt by a moving garage door. When working, the door stops and reverses when it senses something in its path. Typically, the reversing movement comes accompanied by a flashing light and clicking noises. The sensor can fail after long-term use or due to wear and tear. Here are four sensor issues and how to handle them.
Failure Because of Obstructions
Obstructions are the first source of garage door problems. When something blocks the way of the sensors at the bottom of the door, the eyebeam stops emitting the laser beam. When a laser beam does not travel across the opening, yours will not close. Some of the objects that often block the beam include garbage cans and flower pots. Sometimes, the blockage might come from the back bumper of your car, especially when the garage is small. However, if you move the vehicle out and the door still doesn't close, consult a garage repair technician for an assessment.
Failure Because of Sunlight Interference
Sunlight interference is another common reason your garage door sensor might fail because it functions like the human eye. When your sensor receives too much sunlight, it might start to malfunction. Sunlight and sunset are the two times that the beams of sunshine could directly affect the sensors. It is also the time when you go to work and come back home. Therefore, your door could coincidentally fail at these two times.
Failure From Circuit Board Issues
A damaged circuit board is another common cause of garage door problems. The circuit board will get damaged gradually over the years. The circuit board is the motherboard or the computer that operates the door. When it fails, you have to spend large sums of money on the repairs. The technician will only check this component when they have exhausted all other common causes of problems.
Failure From Damaged Wiring
The door has a wire running from the photo-eye to the operator's head. If the staples are installed too tight, you can cut them loose and access the wiring. If the wiring has a short-circuiting issue, replace the eye.
Find a competent garage repair technician to assess your door and determine the extent of the sensor problem. They will recommend the perfect solution to the failed sensors and help improve safety around the garage.
