However, if your garage door opens by itself, nosotros may be able to explain that i and give yous some tips to troubleshoot your garage door operator to prevent it from happening again. Before calling on a professional, follow these steps.
1. Scan the prophylactic sensors.
In garage door operators made after 1993, there are required safety features that open the door during the shut bike when they find something blocking the door. This is done with the assistance of sensors in the motor and on each side of the opening, near the floor and mounted on the tracks. Simply put, if the descending door hits an object, the motor detects the resistance, and the door opens. Likewise, if the axle of low-cal betwixt the floor sensors is broken, the door will not shut.
The slightest detection, such as accumulated leaves, snow or water ice around the garage door, can cause the door to non shut completely. In addition, misalignment of the floor sensors can cause them to not work properly. Carefully examine the infinite effectually the door too as the door tracks, as the sensors tin be misaligned if the tracks are bumped or bent. Likewise, bank check the status of the wires at the sensors and the connections. Fortunately, at that place is normally a blinking light on the opener or at the door operator button that indicates a blockage at the door, merely if you don't come across any blockages, it's also possible that a sensor has just gone bad and needs to be replaced.
2. Examine the garage door opener button.
The door operator button is similar to a door bell. It all depends on the configuration, but you probable take a button that activates the door operator. To troubleshoot the garage door opener push button, make sure it's clean and gratis of debris. The button can hands get dirty and stuck in the "pushed" position. This will cause the door to open and close until the push becomes unstuck. Make clean the button, also as the connections in the housing, if this is the case. And, again, make certain the wiring effectually the opener button is not compromised. If there are bare spots in the wiring insulation, anywhere forth the run of wire, information technology could short excursion and operate the door.
3. Consider the control board and transformer.
If the safety sensors and operator push are working correctly, and no bad wiring or connections are establish, your consequence may be with the control board in the garage door opener itself. A ability surge from a lightning strike or other electrical problem can crusade the board to become bad, equally well as the transformer. If you are handy with a multimeter, you lot can cheque the voltage into and out of the circuit board and transformer. This will confirm if one or both of them are bad and need replacing. Fortunately, if you lot find that youdo demand a replacement and you're already an American Home Shield® customer, your opener may be covered — meaning you thought ahead and protected your budget from this unexpected repair.
Bonus Tip: While we're on the subject, consider installing a surge protector where the operator plugs into the receptacle, to be on the safe side in the hereafter.
4. Get your neighbors involved.
Another possible solution to your garage door problems: Someone else is living shut to y'all with a remote that is programmed with the same code that yours is. This is pretty unlikely, but itis possible. If you accept an former operator, made before 1993, information technology is programmed by positioning clips. You lot can get ahead and reposition the clips and meet if that works. But before you lot do, visit all your close neighbors with garage door operators, ask them to open their doors and see if yours opens, as well. If it happens, case solved.
