Garage Door Limit Switch Problems [Troubleshooting Tips]

When it comes to garage door issues, a common problem is a malfunctioning limit switch. The limit switch is responsible for the proper opening and closing of the garage door.  A limit switch is a mechanical device that signals to the garage door opener when the garage door has reached its limit in terms of travel, either when it is fully open or fully closed. 

This switch is usually installed in two separate locations, each designed to when the door is fully closed or opened. A malfunctioning limit switch will prevent the door from operating as efficiently as it should.

However, luckily, there are a few simple troubleshooting tips that can help you identify and solve the problem. Please make sure, before attempting any troubleshooting, that the power to the garage door opener has been disconnected.

1. To Troubleshoot A Garage Door That Won’t Open Completely 

Open your garage door and measure the gap between the bottom of the door and the top of the garage opening. Then, use a screwdriver to turn the “Up” limit switch adjuster on the side of the opener clockwise by one turn for every three inches of additional height. Test the door and adjust again, if needed.

2. To Troubleshoot A Garage Door That Won’t Close Completely

To close the garage door and regulate the gap between the ground and the door, press the button and use a screwdriver to adjust the “Down” limit switch adjuster on the side of the garage door opener. Turn the screw counterclockwise approximately one turn for every three inches the door needs to be lowered.

3. To Troubleshoot A Garage Door That Closes Then Opens Again

Press the “Close” button to close the garage door. If the door closes and then reopens, adjust the “Down” limit switch adjuster.

Turn the screw in a clockwise direction one turn at a time until the door remains closed when the “Close” button is pressed. Test the door several times and make any necessary adjustments.

Common Garage Door Issues And How To Fix Them

Garage doors are an important part of any home and can require regular maintenance and repair. However, just like any mechanical product, they are bound to encounter one issue or the other. Most of the time, the issues that happen to the garage door are very simple and they can be easily fixed or rectified.

Here are some of the common garage door issues and ways to fix them;

1. Unresponsive Remote

An unresponsive remote is one of the most common garage door issues and a source of frustration for many homeowners. Fortunately, there are a few simple solutions to try that can often resolve this issue. 

First, check the battery on your remote. If the battery is depleted, replace it and see if that resolves the issue. If that doesn’t work, reprogramming the remote may be necessary. This involves resetting the settings on the remote to match the settings on the opener. 

Typically, this can be accomplished by following the instructions in the owner’s manual or contacting the manufacturer for help. If the remote remains unresponsive after these steps, it is advisable to get a new one.

2. Wall Switch Not Responding 

This is another common issue with garage doors. This issue can be caused by a variety of reasons, including electrical or mechanical problems. However, this issue is relatively easy to fix.

Firstly, check the wall switch itself, ensuring it is plugged in, and the connections are secure. If the power is out, check your circuit breaker to see if the breaker has been tripped. If it has, reset the breaker. If the wall switch is still non-responsive, check the wires for any frayed or exposed cables. If any are found, it is recommended to replace the switch.

3. The Garage Door Won’t Close Completely

Garage doors that won’t completely close are a common problem that homeowners may face. Fortunately, this issue is typically easy to fix and can often be addressed without the need for professional assistance. 

The first step is to check the door’s sensors. The sensors are located at the bottom of the door and are responsible for sensing when an object is in the path of the closing door and preventing the door from closing further. 

If the sensors are blocked or misaligned, they will not be able to sense when something is in the way and the door will not close completely. To fix this issue, the sensors need to be cleaned and aligned. Additionally, check the tracks for any damage, such as dents or bent sections.

How Long Do Garage Door Springs Last?

Garage door springs are one of the most important components of a functioning garage door, and their longevity and reliability depend on a few key factors. However, if you use your garage door twice a day, the garage door springs can last for up to 10 years or more

Generally, garage door springs have a lifespan of between 10,000 and 15,000 cycles, with each cycle meaning that the door has opened and closed. Other factors that can affect the life of a garage door spring include the overall quality of the spring, the weight of the door, and the type of spring used. Better quality springs tend to last longer, while springs that are used to support heavier doors will need to be replaced often.

What To Do If Your Garage Springs Break?

If your garage springs break, it’s important to act fast in order to prevent any further damage. First, you should disconnect the opener from the door, as the broken springs can cause it to pull too hard and damage the opener or the door itself. 

Next, you should assess the damage and decide if you need to replace the spring or if it can be repaired. If you decide to replace the spring, you should contact a professional service to do the work, as springs are under high tension and can be dangerous to handle. 

How Long Do Garage Door Sensors Last?

Sensors in garage doors are very important. Typically, a garage door sensor will last anywhere between 3 – 7 years, depending on how often it is being used.

However, sensors may need to be replaced more often if they are exposed to extreme temperatures, moisture, dust, or insects. It is important to regularly inspect the sensors and keep them free of any debris to ensure they are functioning properly. Additionally, proper maintenance and regular maintenance of the system can extend the life of the sensors and keep them in good working order.

Can Garage Door Limit Switch Be Replaced?

Yes, a garage door limit switch can be replaced. However, it is important, to ensure that the new limit switch is the right size and type for the garage door opener. 

How Long Will Garage Door Openers Last?

Garage door openers are generally designed to be very durable and long-lasting products. Depending on the quality of the opener and how well it is maintained, a garage door opener can last anywhere from 10-15 years on average. 

However, regular maintenance is essential in order to keep the opener running in top condition and extend its lifespan. Basic maintenance tasks such as lubrication, adjusting the limit switches, and making sure all of the screws and bolts are securely tightened can help to keep the opener in good working order. 

Additionally, it is important to inspect the opener and power source regularly to ensure that it is functioning properly and that there are no signs of damage or wear. With proper care and maintenance, a garage door opener can last more than 10 years.


Having a malfunctioning garage door can be a huge inconvenience. A limit switch is one of the important parts of a garage door, and if it fails to work properly, it can prevent the door from opening and closing. 

If you’re experiencing a problem with your limit switch, you need to know how to troubleshoot it correctly to keep it functioning properly. We’ve discussed common problems with garage door limit switches, as well as tips on how to troubleshoot them.
