If your garage door opens but does not close, it can be a frustrating problem to fix. If you’ve already tried to manually close the door and found that it doesn’t budge, then there’s likely a mechanical issue with your garage door opener. Fortunately, there are several common causes of this problem that can be fixed with relative ease.

Remote opener.

If you haven’t been able to get your remote opener to work recently, it’s possible that the battery is dead. You should be able to find a replacement at any local hardware store.

If a new battery doesn’t fix the problem, then it’s likely that something else is wrong with your opener. The motor may be broken or damaged in some way (and will need to be replaced). You can also check for other problems if this happens; check that your door is properly aligned with the tracks so it won’t move while opening or closing, and make sure nothing is obstructing its path (such as fallen branches or snowdrifts). If none of these things seem like they could be causing an issue with your garage door opener, then there might indeed just be something wrong with the remote itself—in which case there isn’t much else we can say except “sorry.”

Sensors.

If your garage door opener opens but not closes, you may have a problem with sensors. Sensors can be dirty or have lost their contact with the door. To check this, lift up on the door at one end and release it. If it doesn’t close all the way, you may need to clean or replace them.

If no sensor issues are apparent, check the wiring around your garage door to make sure there aren’t any loose connections or broken wires that could cause problems with closing and opening your garage door.

Lastly, if everything else tests out okay you should try changing out your remote control just in case something got bent during use or transportation when moving into a new house/apartment/office space

Circuit board.

If the circuit board is damaged, the garage door will not close. The circuit board can be damaged by water or heat, or it may simply age out of service. If you notice that your garage door opener isn’t closing after 30-90 seconds of reversing, this may be a sign that your circuit board has failed and needs to be replaced by a professional.

Motor unit.

The motor unit is the “heart” of your garage door opener. It is located inside the wall between your garage and home, or in some cases, it may be mounted to the side of your home. If this piece fails, it could prevent your garage door from opening at all or from closing after being opened.

The motor unit can be replaced if necessary and you should contact a professional for help with this task if you have no experience working on garage door openers.

Chain and drive sprockets.

If your garage door opener is not working properly, it’s possible that one of the chain and drive sprockets has become damaged. The chain is made up of a series of interlocking links that rotate when the motor turns. Drive sprockets are located at each end of this chain, and they help guide the rotation so that your motor can move in and out smoothly. If any part of these components becomes damaged or worn out over time, then they may need to be replaced.

If you suspect damage to either component, take a closer look at them. If you see cracks or fraying along either surface (where it connects with other parts), then it could be time for replacement parts.

Try the solutions listed here to fix your garage door opener.

• Check the power source. Make sure that your garage door opener is plugged into a working outlet, and that it’s not just showing signs of life because one of those outlets happens to be a ground fault interrupter (GFI) that’s tripped. You can identify this type of outlet by looking at its plug—it will have two buttons on it instead of one. If you press these buttons together and nothing happens, then that is likely your issue; but if pressing them causes anything else inside the garage door opener to react, then you should try some other solutions listed here.
• Check the remote control. At times, a remote control can become damaged or lose its signal if something blocks its line-of-sight with the opener unit itself (like an object being placed in front of it), so double check all connections before moving on to other possible causes for failure here!
• Check sensors. If everything else looks good mechanically but there are still issues with opening or closing when trying different methods (such as using either handheld remotes vs traditional wall-mounted ones), then take another look at possible problems with sensors such as photo eyes which are usually located along each side edge somewhere near where cables come up from below ground level before entering inside like mine does here…
