Why is My Garage Door Not Closing?

An automatic garage door is an absolute convenience since one can close it using a remote. This helps you avoid the harsh weather outside leaving your home and certainly returning from anywhere and finding it raining or hailing at that very time. It can help protect your clothing and the interior and exterior of your car, and save you gas money.


Since most people use their garage to not only park their cars but also store tools, extra stuff, and more items, a garage door that does not close properly can be cause a lot of concern. You might be worried about all the things you have stored in your garage and also the garage does lead to the interior of your home which is another reason that if your garage door does not open or close properly, the integrity and security of your home is slightly or openly compromised. This makes it essential that you fix the garage door as soon as possible after finding out that it does not close properly.


In many cases, the causes behind the garage door not closing are easy to identify and fix by yourself. You should first try and fix the problem on your own before contacting a garage door repair service.

  1. 1.Misaligned Sensors

    Is your garage door haunted? Is it broken beyond repair?

    Often the garage door will not close because the sensors are misaligned. If the infrared sensors are not functioning as they should, you will find that one of them is blinking. Check the positioning of the sensors, especially the wiring. If this is tightened, then the sensors will become aligned again, and the garage door will close when you press the remote.

    Sometimes, the path between the sensors could be blocked. In this case you need to remove the obstacle between the sensors in order to ensure that the garage door closes.


    Another reason for the sensors malfunctioning is called dirty eyes. The sensors can become covered with dust or grime and be unable to detect the commands. You can fix this by cleaning the sensors and making sure that they are free of dirt.

    Another way of fixing the sensors is to unplug the garage door opener and replugging it. This will reset the sensors and can fix the problem for you.


    Since, faulty sensors can prevent a garage door from closing, you need to check for these issues and fix them to make your garage door close properly.

  2. 2.Warped Track

    If your garage door only closes partially, this could be a sign that the track is warped. In a properly functioning garage door, the door is lowered or raised on a track. If this track is clogged, warped, or loose, the door will not close. You can check for this by standing inside your garage and watching the sensors as the door comes to a halt. If the sensor light flickers, it means that the track is warped.


    To fix a warped track first clean it with a brush or rag. In cold weather, the grease in the track expands and this causes the track to misalign.


    You can also examine the track for any loose fittings and tighten it to ensure that the door descends smoothly. Sometimes, the track might be slightly bent or misaligned at the place where the garage door stops closing. You can use a hammer and gently tap the track into back into alignment.

  3. 3.Lithium Grease

    A garage door that does not close properly needs to be lubricated. However, not all lubricants can be used on garage door motors. This is because grease attracts dust and grime and can clog the tracks or the motor making it more difficult for the garage door to close. Oil too cannot be used as a lubricant because it runs and can stain the floor of the garage. The best material for lubricating your garage door to ensure that it closes properly is lithium grease. It is an aerosol that can be sprayed. It does not stain or attract dirt and grime that can clog the tracks of an automatic garage door.

  4. 4.Garage Door Opener

    Sometimes the garage door will not close fully because of a faulty adjustment in the garage door opener down limit switch. To rectify this you need to first try to close the garage door and mark the height at which it stops closing. Now open the garage door completely and measure the distance between the floor and the place where the door stopped. This measurement will be used to adjust the down limit switch.


    Next, use a ladder to access the garage door opener motor housing. The down limit switch is located to the side of this housing. Using a flat head screwdriver turn the down limit switch one turn clockwise for every three inch distance that you measured. Once you have done this, try closing the garage door again. It should now close completely till the ground.


    The garage door opener and the down limit switch should also be adjusted if the garage door closes and then reverse. In such cases, you should turn the down limit switch for a single turn using a flat blade screw driver and test the door again by closing it. If the door still reverses after reaching the floor, you need to repeat the procedure until the reversal stops.

Since a garage door is an essential safety device in a home and safeguards not only your car but also the tools and other material you store in the garage, you need to take steps to fix a garage door that does not close automatically. This can be done by checking all the main components of an automatic garage door – the sensors, the track, and the garage door opener. By ensuring that all of these function properly you will be able to ensure that your automatic garage door closes at the press of a remote button.


To ensure that your home and possessions are safe, you must familiarize yourself with the functioning of an automatic garage door opener. This will enable you to troubleshoot and fix problems that prevent the garage door from closing. By following a proper maintenance schedule and checking the door for commonly occurring faults you can fix it on your own.
