Nothing is worse than coming home and finding that your garage door won’t close.

Having a garage is a nice convenience, but it can be a nuisance when things go wrong with your garage door. Knowing what the issue is can help you determine if it’s a problem you can tackle yourself or if it’s time to call for assistance.

Just like any door, your garage door is meant to open and close.

A garage that’s left open can lead to theft, weather damage, and other problems. Don’t leave your valuables exposed or your home unprotected if you find that your garage door won’t close.

To help you troubleshoot your garage door issues, here is a list of simples fixes you can try. 

1. Scan the Area

If your garage door is stuck, or not closing properly, the first step is to check for obstructions. It’s important to check if there’s something under the door, or blocking the safety sensors.

Sometimes, rusted or damaged rollers can cause the door to bind in its tracks. Replacing them, or lubricating them with silicone lubricant can correct this problem.


2. Check the Safety Sensor

If your garage door isn’t closing properly, there’s a good chance that the safety sensors need adjustment or re-alignment. The safety sensors are the electronic eyes that prevent anything from being crushed when the door closes.

If there’s nothing blocking the door and sensors, check to make sure the safety sensor is clean and properly aligned.


Garages are notoriously dirty, and the sensors are often susceptible to dirt and grime. Even a cobweb can sometimes cover a sensor, causing it to malfunction.


3. Try the Wall Sensor

If none of these resolve the issue, move on to the wall station of the garage door opener. Try to press and hold the interior wall station, using constant pressure until the door closes and touches the ground.

If the door successfully closes at this point, then you know the issue lies with the safety sensor.

Sometimes the electrical circuit boards, inside the photo safety sensors, get shorted when wet or during a power surge or lightning strike. You can clean and re-align the sensors yourself. No professionals needed!


4. The Close Limit Switch May Need Adjusting

Your garage door has set-limit switches that tell the motor when to stop running–both during opening and closing. This is a necessary feature which prevents it from closing on someone or something, causing harm or damage.

If the close-limit switch is set incorrectly, it may prevent the door from closing all the way. It can also cause the opener to pull back or reverse when you try to close it.
Adjusting the close-limit switch can help prevent your door from behaving erratically. Most garage door openers have a screw feature on the motor, which allows you to adjust just how far the door descends.


5. Use the Manual Release Cord

Most garage door problems can be traced back to the sensor. If that’s not the case, try using the manual release cord.

Located on the garage door opener, this cord should release the garage door opener from the doors so you can lower it down manually. Your door should be equipped with a handle towards the bottom. This will help you lower the door once it’s released from the opener.
