Garage doors are an essential part of your home, providing convenience and security. However, like any mechanical system, they can experience issues over time. One of the most frustrating problems homeowners encounter is when their garage door keeps going back up instead of closing. This issue can be annoying and may pose a safety risk. In this article, we will explore the common causes of this problem and provide solutions to get your garage door functioning correctly again.
Understanding How Garage Doors Work
Before delving into the reasons behind a garage door that won’t stay down, it’s essential to understand the basic components and mechanisms involved in its operation.

Key Components of a Garage Door System
- Garage Door Panels: The actual door made of sections that lift and lower.
- Tracks: Metal rails that guide the door as it opens and closes.
- Rollers: Wheels that allow the door to move smoothly along the tracks.
- Springs: Torsion or extension springs provide the necessary tension to lift the door.
- Opener: An electric motor that powers the garage door mechanism, typically controlled by a remote or wall switch.
- Safety Sensors: Located near the floor on either side of the door, these sensors detect objects in the door’s path and prevent it from closing.
Understanding these components can help you troubleshoot why your garage door keeps going back up.
Common Causes of a Garage Door That Keeps Going Back Up
There are several reasons why a garage door may not stay down once you attempt to close it. Here are some of the most common causes:
1. Obstructions in the Door’s Path
Description: One of the simplest explanations for a garage door that keeps reversing is an obstruction in its path. If something is blocking the sensors or the door itself, it will automatically reverse.
Solution: Inspect the area under and around the garage door. Remove any objects, such as tools, debris, or even small pets, that may be blocking the path. Ensure the safety sensors are clear of any obstructions.
2. Misaligned Safety Sensors
Description: Safety sensors play a critical role in the operation of automatic garage doors. If these sensors are misaligned or dirty, they may falsely detect an obstruction, causing the door to reverse.
Solution: Check the safety sensors located on either side of the garage door near the ground. Ensure they are aligned with each other and that nothing is obstructing their path. Clean the lenses of the sensors with a soft cloth to remove dust and debris.
3. Damaged or Worn Out Springs
Description: Garage door springs are vital for lifting and lowering the door. If the springs are damaged or worn out, they may not provide the necessary tension to keep the door closed, leading to it reversing.
Solution: Inspect the springs for any visible signs of wear, such as rust or breaks. If you notice any damage, it is crucial to replace the springs. Note: Replacing garage door springs can be dangerous and should be performed by a professional.
4. Problems with the Garage Door Opener
Description: The garage door opener is responsible for powering the door. If it is malfunctioning, it may cause the door to behave erratically, including reversing when it shouldn’t.
Solution: Check the power supply to the opener. Ensure it is plugged in and functioning correctly. If the opener has a reset button, press it to reset the system. If issues persist, consult the owner’s manual or contact a professional for assistance.
5. Incorrect Limit Settings
Description: Garage door openers have limit settings that determine how far the door will travel when opening and closing. If these settings are incorrect, the door may reverse before fully closing.
Solution: Consult your garage door opener’s manual for instructions on how to adjust the limit settings. Typically, there are adjustment screws on the opener unit that can be turned to increase or decrease the closing limit.
6. Damaged or Misaligned Tracks
Description: The tracks guide the garage door as it opens and closes. If the tracks are bent, misaligned, or damaged, the door may not operate smoothly, leading it to reverse unexpectedly.
Solution: Inspect the tracks for any bends or misalignment. If you notice any issues, gently straighten the tracks using a rubber mallet. Make sure the tracks are securely mounted and free of debris. If the damage is severe, you may need to replace the tracks.
7. Faulty Remote Control
Description: Sometimes, a malfunctioning remote control can send intermittent signals to the garage door opener, causing it to reverse unexpectedly.
Solution: Test the garage door using the wall switch instead of the remote. If the door operates correctly from the wall switch but not from the remote, consider replacing the remote battery or consulting a professional if the issue persists.
Troubleshooting Steps to Take
If your garage door keeps going back up, follow these troubleshooting steps to identify the cause and find a solution:
Step 1: Inspect the Area
Check for any obstructions that may be blocking the door’s path. Clear away any debris or items.
Step 2: Check the Safety Sensors
Examine the safety sensors for alignment and cleanliness. Make adjustments if necessary and clean the lenses.
Step 3: Test the Springs
Inspect the springs for signs of wear or damage. If damaged, contact a professional to replace them.
Step 4: Review the Garage Door Opener
Ensure that the garage door opener is functioning correctly. Check the power source and reset the unit if necessary.
Step 5: Adjust Limit Settings
Consult the manual for your garage door opener and adjust the limit settings as needed to ensure the door closes fully.
Step 6: Examine the Tracks
Look for bends or misalignments in the tracks and make adjustments as necessary.
Step 7: Test the Remote Control
Use the wall switch to test the door. If it works from the wall but not the remote, consider replacing the remote’s battery.
When to Call a Professional
If you’ve gone through the troubleshooting steps and your garage door keeps going back up, it may be time to consult a professional. Here are some scenarios where professional help is recommended:
- Spring Issues: If you suspect that the springs are damaged, do not attempt to replace them yourself. Garage door springs are under high tension and can be dangerous.
- Opener Problems: If your garage door opener is malfunctioning and you cannot identify the issue, a professional can diagnose and repair it.
- Track Alignment: If you are unable to fix the tracks yourself or if they are significantly damaged, it’s best to call in an expert.
- Safety Concerns: If you notice any strange noises, movements, or if the door operates erratically, it’s important to seek professional help to avoid potential injuries or further damage.
Preventive Measures
To prevent your garage door from keeping going back up in the future, consider the following preventive measures:
- Regular Maintenance: Schedule regular inspections and maintenance for your garage door system. This can help catch potential issues early.
- Keep the Area Clear: Ensure the area around the garage door remains clear of obstructions to allow for smooth operation.
- Lubricate Moving Parts: Regularly lubricate the rollers, hinges, and tracks to reduce friction and ensure smooth movement.
- Test Safety Features: Periodically test the safety features of your garage door to ensure they are functioning correctly.
- Educate Household Members: Make sure everyone in your household understands how to operate the garage door safely and what to do in case of a malfunction.
Conclusion
A garage door that keeps going back up can be a frustrating issue, but understanding the potential causes and solutions can empower you to troubleshoot the problem effectively. By conducting regular maintenance and addressing any issues promptly, you can ensure your garage door operates smoothly and safely for years to come. If you find yourself in over your head, don’t hesitate to reach out to a professional for assistance. A functional garage door not only enhances your home’s convenience but also contributes to its overall security and aesthetic appeal.
