How to Fix Garage Door When It Won't Close

With the right tools and a bit of know-how, you can soon have your garage door working again – no need for a technician to visit! So read on as we provide guidance on how to fix common problems like misaligned sensors, and wandering rollers and how to fix garage door when it won’t close.

What Causes Garage Door When It Won’t Close?

1 . Sensor Misalignment

One of the most common causes of a garage door not closing is sensor misalignment. Garage doors have sensors on either side of the door near the bottom, and these sensors are responsible for detecting obstructions in the path of the closing door. If they are not aligned properly, they may think there is an obstruction when there isn’t one. This can cause the door to reverse and not close properly.

2. Sensor Malfunction

In addition to misalignment, sensors can also malfunction. This can happen if they are dirty, damaged, or simply worn out over time. When sensors don’t work properly, they may not detect obstructions or may think there is an obstruction when there isn’t one. Regularly cleaning and maintaining the sensors can help prevent malfunctions.

3. Track Obstruction

The track is another potential cause for a garage door not closing properly. If there is an obstruction in the track, such as debris or an object, it can prevent the door from closing all the way. Check the tracks regularly and remove any obstructions to ensure smooth operation of the door.

4. Broken Springs

Garage doors are heavy and rely on springs to help lift and lower them. If the springs are broken or worn out, they may not be able to support the weight of the door, causing it to either not close properly or not close at all. It is important to have a professional replace any broken or worn out springs to ensure the safe operation of the garage door.

5. Limit Setting Issue

Modern garage doors have a feature that allows you to set a limit for how far the door should close. If this limit is not set correctly, it can cause the door to stop closing before it reaches the ground. This could be due to a power outage or someone accidentally adjusting the settings. Check the limit settings and adjust them if necessary.

6. Power Outage

If there is a power outage, your garage door may not close properly since it relies on electricity to function. Some garage doors have a battery backup system for these situations, but if yours does not, you may need to manually close the door until the power comes back on.

12 Ideas on How to Fix Garage Door When It Won’t Close

1 .  Check the Safety Sensors

If your garage door won’t close, the first thing you should do is check the safety sensors. These sensors are located at the bottom of the garage door tracks and prevent the door from closing if they detect an obstruction. Make sure there isn’t anything blocking their view or that they aren’t misaligned. If they are misaligned, adjust them until the LED light on each sensor is lit up and solid.

2. Clean the Tracks

Over time, dirt and debris can build up on the tracks of your garage door, causing it to malfunction. Use a damp cloth to clean the tracks and remove any obstructions or buildup that may be preventing the door from closing properly.

3. Lubricate the Moving Parts

If your garage door is making unusual noises or struggling to close, it may be due to a lack of lubrication. Use a silicone-based lubricant to grease the moving parts of your garage door, including the tracks, hinges, and rollers.

4. Check the Springs

The springs on your garage door play a crucial role in its functioning. If they are damaged or worn out, it can cause the door to become unbalanced and prevent it from closing properly. Check for any signs of damage and consider replacing them if necessary.

5. Adjust the Limit Switches

The limit switches on your garage door control how far up or down the door will go. If these switches are not set correctly, it can cause the door to stop before it is fully closed. You can adjust these switches by following the instructions in your garage door manual.

6. Inspect the Rollers

If your garage door won’t close smoothly or keeps getting stuck, it could be due to worn out rollers. Check for any signs of damage or wear and tear and replace them if necessary. Also, make sure the rollers are properly aligned and lubricated.

7. Tighten Loose Hardware

Vibrations from the constant opening and closing of your garage door can cause hardware to become loose over time. Check for any loose bolts or screws and tighten them with a wrench if needed. Also, check the hinges and make sure they are secure.

8. Replace the Weatherstripping

Weatherstripping is the seal that lines the bottom of your garage door. If it becomes damaged or worn out, it can cause gaps that may prevent the door from closing properly. Replace any damaged weatherstripping to ensure a tight seal.

9. Check for Obstructions

Sometimes, the reason your garage door won’t close is simply because there is something in the way. Check the tracks and the area around your garage door to make sure there isn’t anything blocking its path.

10. Inspect the Cables

The cables on your garage door are under a lot of tension and can become worn or frayed over time. If you notice any damage to the cables, it’s best to call a professional for repairs. Also, make sure the cables are properly aligned and not tangled.

11. Test the Garage Door Opener

If your garage door won’t close with the remote or keypad, try opening and closing it manually. If it works fine manually but still won’t close with the opener, there may be an issue with the remote or keypad. Try replacing the batteries or reprogramming the opener to see if that solves the issue.
