The garage door is a faithful servant that will close and open uncountable times in an average residential home. Consequently, it requires regular maintenance to manage its susceptibility to frequent tear and wear.
At times it could be a mild problem that you can fix all by yourself. Other times you may need to call a professional technician such as those at overhead door Fort Worth to help you fix it. Even before you call in an expert, you may troubleshoot the head door issues.
The photo eye’s blocked, dirty or misaligned
If your garage door is not more than 20 years, it has photo eyes on either side of the overhead door entrance. Photo-eye functions to detect a person or object blocking the overhead door from coming down all the way.
A garage door has two main elements; the line of sight and the photo-eye. Photo-eye infrared sensors are placed about six inches above the ground. When the remote control is pressed, the photo-eye sends a signal to the sensors, causing it to open the door.
If nothing is blocking the door when opening, the photo-eye on both sides of the door will trigger the sensor to open it. If something is blocking it, and the beam is blocked, the door will not shut.
So, inspect both eyes for any dirt that could be blocking the light from the beam. Clean the laser beam with a soft clean tissue. If the sensor is moved out of position, it can send a signal that there’s an obstruction on its path. Check the light in the sensors to make a judgment on alignment. If the light is blinking, then, they’re misaligned. Solve this challenge by tilting the sensors to their correct orientation.
Transmitter batteries are dead
You may say this is a no brainer, but the transmitters need batteries to work. If the dry cells are dead, the transmitter cannot send a signal to have the door open. Does the transmitter on the wall open the overhead door when pressed? If it does, the transmitter cells of your car likely need a new set of batteries. If you have two or more transmitters for your garage door, replace all of them because you probably changed them around the same time.
Replacing the transmitter battery is simple. Most require you to slide the back of the transmitter opens then remove the cells. Use a screwdriver if screws are used to place batteries in place.
When placing the new pair, ensure the negative and positive signs on the battery match the same signs on the transmitter. If interchanged, the transmitter won’t work and may give you the impression that something else could be the problem.
Torsion springs are broken
If the garage door won’t go up even with working batteries and functioning photo-eye, you need to check the torsion springs. Broken torsion and extension spring is one of the most dangerous overhead door issues anyone can experience.
Garage doors are held in place by springs. Because of the high tension, should they break, they produce such a loud bang that one would mistake for firecracker intensity. Damaged broken springs can cause misalignment and improper shutting of the door.
Regularly inspect the doors to detect any loose springs that need an expert skill to fix. Handling torsion springs can be risky. You should never attempt repairing torsion springs yourself.
Instead, call a professional technician near you to help fix the issue. A qualified garage door professional uses the right tools and skills to repair the door.
Faulty limit settings
Your garage door opens smoothly but suddenly snaps up again letting the entrance open. If this describes your issue, then, the limit setting needs adjustment. These are settings that allow the door to close and open when it’s required to.
If the limit switch is incorrectly programmed, the door flies open immediately it touches the ground, or, refuses to open or shut all the way. Ordinarily, this is a safety measure that prevents the door from shutting down on someone.
To fix it, open the door and keenly observe it as it opens. When it opens around five feet above the ground and then stops, the limit up the door needs adjustment.
Next, take the height from the ground to where the door stopped. The measurement will help fix the up limit switch. Turn the limit-adjustment screw clockwise. Likewise, if the door closes partially, turn the lower adjustment screws clockwise.
