There is not many things more frustrating than a garage door system that suddenly refuses to close. Whether you’re heading out for the day or trying to secure your home in the evening, a stuck garage door disrupts your routine and can pose a risk to the safety and security of your property. Fortunately, many of the most common issues behind a stuck garage door are simple to identify – and often easy to resolve without professional help. In this guide, we’ll explore some of the most frequent causes, walk you through some step by step troubleshooting and explain when it’s time to call in a garage door expert like the team at Jims Garage Doors.
Common Reasons Why Your Garage Door Won’t Close
Understanding the potential causes of a stuck garage door is the first step in getting the issue rectified quickly and safely. Let’s explore some of the most frequent issues:
Blocked or Misaligned Safety Sensors
Modern garage doors come equipped with safety sensors, small devices located on either side of the door near the floor, that prevent the door from closing if something is in the way. If your garage door won’t close, there’s a good chance that these sensors are either blocked or misaligned. Dirt, spider webs or accidental bumps from bins or equipment can easily knock them out of position. Most models of sensor will flash a red or orange light to indicate a problem. A solid green light on both sides generally indicates that the sensors are aligned and working as intended.
Obstructions In The Track or Pathway
If your garage door system starts to close but then stops midway or quickly reverses, there could be something obstructing the track or pathway. This is usually attributed to a lack of servicing, causing the door to become too heavy for the opener itself. Leaves, small tools, boxes among other things can cause the safety sensors to trigger or physically block the door’s path. It’s also important to inspect the metal tracks along the sides – if they’re bent, warped or clogged with built up grime and dirt, the door may not close properly.
Garage Door Opener Malfunctions
Sometime the issues lies with the garage door opener itself. Weak or dead remote batteries are a common and easy fix, but other faults like power supply issues or logic board malfunctions may prevent the opener from responding to commands. If your wall button works but the remote doesn’t, or vice versa, you may need to replace the batteries or reset the opener.
Broken Springs or Cables
A garage door opening mechanism relies on tightly wound springs and sturdy cables to lift and lower smoothly. If a spring snaps or a cable becomes loose or frayed, the door may refuse to close – or worse, come crashing down unexpectedly. These issues can often be detected by loud banging noises, uneven door movement or visible fraying. Do not attempt to repair broken springs or cables yourself, as these components are under extremely high tension, are very dangerous to handle and have the potential to cause serious injury without proper training.
Limit Setting Errors
Your garage door opener has inbuilt limit settings that tell the door how far to move when opening or closing. If these settings are incorrect – whether due to errors during installation, wear over time or power outages – the door may think it has reached the floor before it actually has, causing it to stop short or reverse. This issues is common in newly installed systems and can usually be adjusted on the opener.
Step By Step Troubleshooting Tips
If your garage door won’t close, try these safe, simple steps before calling for professional help. In many cases, the issue is minor and can be resolved quickly with a bit of attention and basic tools. These troubleshooting techniques are designed for homeowners to assess the most common causes without the need for technical expertise or specialist equipment.
Inspect & Clean The Safety Sensors
Start by gently wiping the safety sensor lenses with a soft, dry cloth to remove dirt or cobwebs. Then, check that both sensors show a steady green or amber light. If one or both lights are blinking or off, realign them by adjusting their angle until the lights return to solid. This usually fixes garage door sensor issues in just a few minutes. If your issues persist, get in touch with a specialist garage door technician like Jims Garage Doors.
Check For Visible Obstructions
Carefully inspect the entire path of the garage door, including the area where the door rests when closed. Remove any debris, garden tools or loose items that could potentially be blocking the door’s path. Don’t forget to examine the side tracks for dirt or grime build up, as well as dents that might be interfering with the rollers.
Test The Opener System
If there are no visible obstructions. Try using both the wall-mounted button and the remote control. If only one works, it could be a battery issue or faulty remote. Replace the batteries and try again. If neither option works, the opener may need to be reset. This is usually completed by unplugging the unit for a few seconds or pressing a dedicated reset button, depending on the model of your opener. If you have the owner’s manual handy, it’s always a good idea to refer to it to understand the reset protocols for your particular model.
Try Manual Mode
If your garage door still won’t close, you may try switching it manual mode by pulling the red emergency release cord (usually located near the opener rail). However, if the door is stuck open, do not attempt this yourself. A broken spring or cable could cause the door to fall suddenly, creating a serious safety risk. In this case, call a professional garage door technician first.
If the door is mostly closed, it’s safer to test manual operation. Pull the cord to disengage the opener and gently try to lower the door by hand. If it moves freely, the issue may be electrical. If the door is heavy, stiff or uneven, the fault is more likely to be mechanical – such as a bent track or damaged spring – and requires professional repair.
When To Call A Professional
While many stuck garage door problems can be resolved with some simple DIY fixes, some issues are better left to the experts. Here are a few scenarios where you should call a professional instead of trying to fix it yourself:
- The door won’t move at all, even in manual mode
- There are visible frayed cables, broken springs or bent tracks
- Sensor issues persist despite cleaning and realignment
- You’ve already tried resetting the opener with no success
For these types of problems, continuing to operate the door can lead to further damage or put your safety at risk. The team at Jims Garage Doors is available for fast, reliable garage door repairs and servicing.
Preventing Future Closing Issues
The best way to avoid a stuck garage door in the future is to ensure you are maintaining the system regularly. Preventative garage door maintenance not only extends the lifespan of your system, but it also reduces the likelihood of experiencing frustrating breakdown events.
- Inspect your door and its moving parts monthly
- Clean the tracks and safety sensors regularly
- Test the auto-reverse function with a soft object
- Lubricate hinges, rollers and springs with a garage door lubricant every few months
- Avoid storing objects near the door’s pathway
