Garage doors go through a lot in a typical day. Every time you drive in and out of it, so many internal movements occur, and that's why these doors eventually succumb and break down. However, some cases are fairly simple and can be troubleshot without any hassle. So if you've got a garage door, here are some of the three common faults that you can easily troubleshoot.
Opener makes a grinding noise
In some cases, the garage door opener motor produces a continual grinding sound, but the door remains still. This is a sure sign that your main gear is fried up. It's the part that comes into contact with the worm drive gear when moving the door.
Replacing the gear is the best solution. All you have to do is pull out the gear as one piece using a punch. The main gear should come out with the sprocket and shaft. Afterwards, replace it with your new kit. Don't forget to apply enough lubricant.
Door opening and closing by itself
This problem is normally caused by a short-circuiting either in the wall button or transmitters. A short-circuiting causes a continual signal to be sent to the door. This is what causes the opening and closing. To know your culprit, remove the transmitter batteries, and use the wall button to operate the door. Sometimes the problem is intermittent, so you may want to do this for a couple of days to be sure. If the door operates smoothly, then the transmitters are faulty.
Ensure that your transmitters are not stuck or under a weight that affects them. You could also replace their batteries.
However, if it persists, remove the wall button wire at the motor head. This is to determine if the problem originates from the wall button. Now operate the door using only the transmitters, and if it works, then the problem is probably the wall button.
All you have to do is replace its wires.
An upward bow is a sign that the door travels a long distance up and down. The door needs to move upwards in a way that it'll be just as high as the doorjamb. Ensure your door stop prevents the carriage trolley from hitting the opener. Otherwise, it may ruin it.
Find the opener motor, and using a screwdriver, rotate the travel limits adjustment screws till you achieve your required distance. Operate the door and see whether you need further adjustments.
