Let’s face it: as a homeowner, you don’t pay much thought to your garage door as in your mind it’s a simple device that only needs to do two things: open and close. For the most part, your garage door operates as expected with your automatic garage door opener.
But then one day, the worst happens: you press the button on your remote control to close your garage door, and it doesn’t work. The door either comes down about an inch and goes back up, or nothing happens at all.
Why is that happening? The following gives some potential causes:
Dirty Photo Eye Sensor
There are ‘photo eye’ sensors located on either side of your garage door about six inches from the ground. One sensor projects an invisible beam of light towards the other; if there’s a disruption between the sensors, the garage door will stop closing.
Did you know the most common reason for garage doors stuck in the open position is simply down to dirty photo eye sensors? As you can imagine, the fix to that problem is easy: clean any dirt and debris from the front of each sensor.
You can clean them using a soft cloth and some streak-free glass cleaner. Once you’ve done that, check the sensors are securely bolted into place. Sometimes, misalignments can occur if one or both sensors aren’t affixed to the walls properly.
As part of your regular garage door maintenance, you should ensure both photo eye sensors are always clean and able to work as intended.
Worn Garage Door Rollers and Bearings
Did you hear a strange popping or squealing sound whenever your garage door opened and closed? If so, the noise may indicate a problem with the garage door’s rollers and bearings. The culprit is usually a lack of grease lubrication.
The popping sound is due to worn rollers, while the squealing gets caused by bearings that require lubrication. Either or both of those issues could be the reason your garage door isn’t closing correctly.
Broken Garage Door Torsion Springs
Your garage doors have torsion springs. Their job is to enable your garage door to open effortlessly, but as with any steel springs, they will eventually wear out. In some extreme cases, they can snap!
When your garage door torsion springs no longer function correctly, they can make the process of opening and closing your garage door almost impossible in the worst-case scenarios.
Garage Door Opener Problems
Last but not least, your garage door opener could be the reason why your garage door is stuck in the open position. The cause of the issue might be something as simple as flat batteries in your garage door remote control.
Of course, some problems might be down to the garage door opener itself, such as an electronic or electrical issue. In those cases, a professional diagnosis and repair makes sense as it’s not a simple task for the home DIYer to tackle independently.
