Why Won’t My Garage Door Close? 5 Common Problems Explained

When your garage door starts acting up, it can be a recipe for disaster. You press the remote a few times, maybe even give the door a nudge, but still wonder, “Why won’t my garage door close?”

It’s not just frustrating, it’s also a security risk. An open garage door is like an open invitation for trouble. Not to mention, it’s a safety hazard.

There are a couple of reasons why your garage door won’t close. 

Here are 5 common problems which you should be looking out for. Learn how to spot telltale signs of specific issues and what you can do to troubleshoot before calling in professional garage door services for a fix.

Why won’t my garage door Close – 5 issues to watch out for

When your garage door refuses to close, it can be difficult trying to look for a starting point. 

There’s no need to worry, it’s usually due to a few common issues. They’re usually mechanical issues that cause the garage door to stop dead in its tracks.

Many of these issues can be fixed with a bit of knowledge and some elbow grease. Sometimes, a simple fix is all it takes to get your door moving again.

Issue #1 – Faulty, dirty, or obstructed sensors

Garage door sensors are like the watchful eyes of your garage. Positioned near the floor on either side of the door, they transmit an invisible beam across the opening. 

If anything interrupts this beam while the door is closing, the sensors tell the door to stop and reverse. It’s a nifty safety feature designed to prevent accidents and injuries.

Now, these sensors can be a bit finicky. A speck of dirt, a spider web, or even a slight misalignment can throw them off. 

A lot of them are highly sensitive, reacting to just about any obstruction. It’s frustrating, but at the end of the day, it’s all for your safety.

Fixing sensor problems

First, check if something is blocking the sensors. Clear away any debris. 

Next, clean the sensor lenses with a soft cloth. Sometimes, that’s all it takes. 

If they’re still acting up, make sure they’re properly aligned. The sensors should be pointing directly at each other, with no wiggle room. 

If they’re not, gently adjust them. 

Always remember to unplug the garage door opener before fiddling with the sensors to avoid any accidents.

Issue #2 – The transmitter battery is dead

Ever push the button on your garage door remote and nothing happens? 

That’s a classic sign of dead transmitter batteries. If your remote suddenly stops working or only works intermittently, the batteries are likely the culprit.

It’s easy to overlook, but these little devices need regular battery replacement. Ideally, you should swap them out once a year to keep everything running smoothly. 

Be sure to consult your manufacturer’s manual on how to properly replace batteries. 

Issue #3 – Broken springs

There are two main types of garage door springs: 

• Torsion springs, which are mounted above the door. 
• Extension springs, which run along the sides. 

Torsion springs twist to generate tension, while extension springs stretch and contract. 

Without these springs, your garage door opener would struggle to lift the heavy door, and manual operation would be nearly impossible.

Broken springs announce themselves with a loud bang, almost like a firecracker going off in your garage. Other warning signs include the door not opening evenly or refusing to lift at all. If you suspect a broken spring, be careful. 

Be careful when trying to fix these springs because they are under high tension and can cause serious injury if handled improperly. To be on the safe side, it might be best to get the help of professional garage door services to sort the problem out.

Issue #4 – Worn cables

Garage door cables work with the springs, helping to lift and lower the door safely. When the door is raised, the cables wind around drums or pulleys, and when it’s lowered, they unwind. 

These cables bear a lot of tension, making sure the door’s weight is evenly distributed and manageable.

Over time, garage door cables can wear out or break down. 

Look out for visible wear and tear, fraying, or the door hanging unevenly. 

You might also notice the door is struggling to open all the way or close smoothly. It’s like trying to close a heavy double door with just one arm. 

A garage door will struggle with worn cables. You’ll need to fix these issues immediately to avoid further damage or potential safety hazards.

Repairing or replacing cables

If you suspect your cables are worn or broken, first assess the extent of the damage. 

If you see significant fraying or the door is severely uneven, it’s time to call a professional. Garage door cables are under high tension, making DIY repairs risky. 

However, if you’re confident in your skills, ensure you follow safety precautions meticulously, such as releasing the tension from the springs before attempting any repairs. 

Issue #5 – Track obstructions

Garage door tracks can easily get obstructed by everyday debris, small objects, or even a stray garden tool. Sometimes, being careless at home and leaving things around can block a track. 

Other hard-to-spot culprits include dirt, leaves, and pebbles. Occasionally, the tracks themselves can become bent or misaligned, further complicating the situation. 

Without a clear path, a garage door will simply refuse to close.

Clearing and maintaining tracks

Keeping your garage door tracks clear and well-maintained is important. Here’s a simple guide to help you out:

1. Look for any visible debris or objects blocking the path. Check for bends or misalignments.
2. Use a brush or vacuum to remove dirt and debris. For stubborn grime, a damp cloth with mild detergent can do wonders.
3. If the tracks are bent, gently straighten them with a rubber mallet. Make sure they are parallel and level. An alignment tool can come in handy with this step.
4. Apply a suitable lubricant to the tracks, rollers, and hinges to keep everything moving smoothly.
5. Make it a habit to inspect and clean the tracks monthly. It’s a small task that can prevent major issues.

When to call professional garage door repair services

There will be times when it’s simply better to call in the professionals. Knowing when to call professional garage door repair services can save you time, money, and potential injury. 

Complex problems like broken springs, severely worn cables, or major track misalignments often require specialized tools and expertise that go beyond a simple fix.

Safety is a major concern when dealing with garage doors. 

The high tension in springs and cables can pose serious risks if not handled correctly. Any mistake in repairing these components can lead to severe injuries or irreparable damage. 

Additionally, the weight and size of the garage door itself make it dangerous to work on without the proper knowledge and equipment.

Professional garage door technicians are trained to diagnose and fix a garage door efficiently and safely. They can spot issues that might not be obvious to the untrained eye and provide long-lasting solutions. 

By calling in professional help for more complex repairs, you can have peace of mind your garage door operates safely and smoothly.

Everyone is looking for a quick fix when it comes to broken garage doors. But it’s also about doing it safely and correctly. When in doubt, call in the experts. 

Keep your garage door in tip-top shape

Your garage door is a major entrance to your home. So it’s only right that you keep it working and in excellent condition. 

Common garage door issues have their own set of noticeable signs and fixes. 

The good thing is, that regular maintenance and fast action to these warning signs can keep your garage door working for years to come.

Taking a bit of time to inspect and maintain your garage door can save you from bigger headaches in the long run. 

Don’t forget, there’s no shame in calling a professional for help. Better to have it fixed right the first time, rather than spending more on multiple repairs.
