How to Repair a Garage Door

A broken garage door can either be a mild annoyance or a life-changing inconvenience. Hence, it is critical to analyze what is causing the problem and know how to fix the garage door. Even if there are multiple garage door types, it’s crucial to understand that most operate on a similar level. Regardless if it’s a glass garage door or an older model, the technology involved is mostly the same. If a person searches for “how to fix a garage door,” the knowledge bestowed upon them should apply to all garage door types.

As mentioned earlier, the first step to repair garage doors is through an analysis of the problem. Is it the garage door sensors that is causing the issue? Perhaps it is the garage door opener? Regardless of what is causing the initial problem, a person needs to figure out what to do next to fix it. Typically, the two most common problems are associated with the garage door spring and opener.

Fixing a Garage Door Opener

Garage door openers are convenient, but they are prone to numerous mistakes prone to repair. Garage door problems are more complicated than “get a new opener.” Therefore, a person needs to look deeper into the situation at hand. Usually, a garage door opener should have a reversible motor that helps the carriage move along a rail. This carriage should have a drawbar that influences how a door opens and closes. In turn, this drawbar should have some assistance from additional devices that limit the object from traveling so that the door closes and opens at the right location.

In the case a person owns an opener with a radio receiver, it is vital to know the basic layout associated with it. An example is two wires, black and white (or red), connect the motor unit terminal strip with the receiver terminal strip. The cables should be connected well, as the black wire is typically displayed with a (-) sign next to it, and the white (or red) wire usually has the (+) sign next to it. The motor unit terminal strip should be on the motor unit for the garage door opener, and the radio transmitter sends a signal to the receiver terminal strip. Hence, a signal should be sent straight along the wires to the other side to get the desired effect.

How to Fix Garage Door Problems Associated with the Opener

First, it may be a good idea to learn how a person should install the garage door opener as it can be the easiest fix garage doors can need. If a person needs an opener for LiftMaster, they should seek Ben’s Garage Door and Gate Supply. Ben’s Garage Door and Gate Supply is an authorized dealer for several essential garage door parts, including garage door openers about LiftMaster. As an authorized dealer, any garage door owner should be relieved knowing that the new opener has been tested to work for LiftMaster garage doors.

Now, it’s essential to know where to start. First, install the garage door opener’s mechanism somewhere near the center of the garage door. If a person is unsure where to place the opener, they should try to measure their door’s width. Half of the distance, better known as the midway point, is essential for placement. Knowing this, the owner should place the opener at the midway point. As far as the drawbar is concerned, it’s a similar deal, except vertically. Ideally, the garage door weight should feel balanced around the lifting point.

Next, a person should test out the capabilities of opening and closing the garage door. A person needs to see how far a garage door can open and close. Later on, he or she must mount the garage door opener in a way where its rail won’t be lower than how far the door travels. Remember, the door should not hit the rail!

Afterward, a person needs to find the spot to attach one part of the rail (front end). When a garage door lacks its structure, it’s best to install a mounting board on the front. Using something like a 2 x 6-inch wooden board can help know how high a door can travel, especially as a person can mark it with the relevant measurements they need for their specific garage door.

With the motor unit on hand, place the rail onto it. Usually, a garage door opener should come with an instruction manual of some kind. If you do not have it, seek an online version of the opener you have purchased. Assuming the garage door is optimal, it is crucial to put one end of the rail toward the measurements you should have made in the last step. Those intersecting marks should be two inches below the mounting plank, allowing anybody to try and install the rail bracket. If some supplies are missing, such as nuts and bolts, it is ideal to buy some for this assignment.

Then, drill holes in the relevant areas are disclosed in the instruction manual. It should go through the mounting plank, but the bolts should not be pressed too hard into it. Afterward, the motor assembly should be placed toward the horizontal rail. Physically test out opening the garage door to see if the rail does not disrupt the garage door’s movement. If so, you need to readjust it. Metal brackets can hold the garage joists in a suitable spot, especially if you use the 2 x 6-inch wooden board to assist in measurements. All of these actions are instrumental in the creation of the garage door ceiling.

install drawbar garage doorDrawbar for garage doors

Next, you should seek to place the drawbar toward the carriage. Move it so it’s closed, and then mark the drawbar for future screw holes, which is instrumental for later drilling. Then, install the drawbar and tighten the relevant hardware to the door. Adjust anything that seems out of place or installed incorrectly. An example is seeing where the bolts interact with the chains and what distance is limited from that interaction.

Try to install the radio receiver alongside the manual button. Some people may opt to install an optional key switch, while others may not. It’s more of a preference thing, yet it can greatly assist the opening and closing process. Aside from that, it is imperative to plug in the cord of the drive assembly into the closest extension cord. That, in turn, is plugged into a receptacle. Test the manual push button to see how the garage door operates in action. You may need to see if the extension cord gets stuck or not as the door opens and closes. Otherwise, make the appropriate adjustments to the garage door and opener. If the radio works, then that is a success!

Afterward, disconnect the extension cord and place the drive assembly cord into its new outlet (which it should stay in until another problem arises). If your garage has an overhead light socket, you can opt to connect the cord there. Otherwise, you can handle garage door repair, especially in the scenario involving an opener.

Wiring Safety Sensors to a Garage Door Opener

garage door sensor


Safety sensors are a delightful little device capable of preventing automatic garage doors from causing severe damages. Some safety sensors are universal (works with every garage door), while others are limited to specific brands like LiftMaster. Regardless of which one you own, it’s important to know how you can wire it to your garage door opener without relying on outside help.

Most modern sensors alert the user if there is an issue in some capacity. Some obvious signs include:

  • Garage door behave erratically (stopping and reversing directions out of nowhere)
  • Light flashing on the safety sensor
  • The safety sensor is visibly overheating.
  • There is a lot of dirt or bends on the safety sensor.

Like the previous entry on this article, it is crucial to identify what is the problem. First, look at the sensor and see what can potentially be causing issues for you. If it’s dirt, then you can easily clean it up. You can readjust bends relatively easily as well. Otherwise, it may be best to replace the safety sensor outright for both safety and financial reasons. If you’re replacing it, you may need to adjust the wires.

If you already have pre-existing wires, you need to strip nearly half an inch (approximately 7/16 of an inch) of the insulation for both the black and the white wires. It would then help if you decided which colored wire is going to be spliced with the aforementioned wires. The colored wire with the white and black wire goes into the gray terminal for the motor unit. Likewise, the entirely white wire goes next to it.

You do not have pre-existing wires in the scenario, and then you need to do the same stripping process as listed above. More than likely, you’re going to do so with four total wires (two black and two white). You need to twist the same colored wires together (black with black, white with white) from the sensors. Like in the previous paragraph, you connect the white and black wire to the gray terminal and the fully white wire in the white terminal nearby. Overall, this should significantly assist with the functionality of the safety sensors.

If you cannot make a quick connection involving plug-in terminals with or without existing wires, then there are alternative ways to safely setting up a safety sensor for your garage door. You can try to mess around with screw terminals. In this scenario, you need to do the same stripping as before (7/16th of an inch) and then twist the same colored wires as in the paragraph above (white with white, black with black). The main difference lies in how you plug it in. You need to connect the two black wires to the 3rd screw terminal within the motor unit.

Assess if You are Capable of Handling Safety Sensors on Your Own

If safety sensors prove to be too difficult for you to handle on your own, then do not hesitate to contact a professional to assist you. Of course, some instrumental safety tips can help improve your success rate.

Tip number one is to not work with wires when you have wet hands or live in a humid environment. This tip should be evident to most folk, but it cannot be stated enough how essential it is to your safety.

The next trick is to follow any instruction manual that comes alongside the safety sensors. If it’s a universal safety sensor, then there should be a ton of videos and physical guides that can assist you along the way if text alone cannot aid you. In the case you can handle it on your own, you should find it a handy skill for future repairs.

Other Tips on How to Fix the Garage Door

Remember, some people may be visual learners. If reading isn’t enough for you, you can always try to look up videos on YouTube for more in-depth clarification. If worst comes to worst, don’t hesitate to ask a professional to help you in the garage door repairs process!

Fixing a Garage Door Spring and Other Parts

First and foremost, be aware that if your garage door only possesses one torsion spring near the garage door center, it’s advisable not to try to perform any repairs associated with it by yourself. Instead, you should always call a professional garage door maintenance specialist that specializes in garage door repairs. It isn’t as simple as looking up “how to fix a garage door,” as the inertia associated with the spring, when let go, can cause significant damage. Amateurs can handle garage repairing at a general level, but it’s best to leave it to the pros of being dangerous.

Ben’s Garage Door and Gate can supply you with the necessary garage door springs for Diamond Springs on a similar topic. As an authorized supplier of various garage door parts, Ben’s Garage Door and Gate can assist any homeowner or commercial property owner with their garage door issues. In this scenario, owners interested in Diamond Springs can get theirs from Ben’s Garage Door and Gate efficiently.

Aside from that warning, there are some things a person can do to help fix general issues associated with their garage door. The spring mounting bracket holds the spring together, which itself is attached to the adjustment holes. When working together with the roller and the track, the garage door should open and close all fine and dandy! In issues related to roll-up doors, one can always adjust the spring tension and then pull the cable to adjust the end to either be shorter or longer.

Otherwise, it’s similar to fixing the opener as far as steps go. First, analyze what may be causing the problem. If you do not know what the issue is, you cannot attempt to fix it. After you are aware of the root of the problem, it’s time to perform the first real action. Generally, metal tracks should have the mounting bracket tightly attached to the wall. If it’s loose, that’s a problem and needs to be readjusted if so. You can always use a rubber mallet to fix specific dents and other minor damages.

If the tracks are damaged beyond a simple repair, it’s advisable to replace them outright. It isn’t just safer to replace a damaged track, but it’s also cheaper. Nonetheless, it is paramount that the alignment of the garage door is done correctly. For instance, horizontal tracks generally slant at a slight angle downwards in the direction of the garage’s backside. In the case involving roll-up garage doors, the vertical track should be upright.

If the tracks are not aligned, do not remove the screws that support them. Instead, loosen it to readjust its position. You can do so by tapping the tracks gently (remember, you don’t want to buy a new one right away). After this is done, recheck the alignment and repeat the process and until it’s aligned properly. Once it’s done correctly, tighten the screws and other parts for safety.

As with all things in life, the equipment relevant to a garage door often needs to be cleaned and maintained. Before replacing it, you should try to clean the garage door parts with specially designed cleaners. This aspect should make working conditions more sanitary and remove potential obstacles like dirt and oil. Even after you are done fixing a garage door, it is vital to perform maintenance checks now and then. Doing maintenance can prevent your garage doors from breaking down, and it’s always more financially advisable to prevent accidents than to clean up after the fact.

Assuming the garage door is not fixed, and you just finished cleaning, it’s time for the next step. After cleaning, it is important to see all physical parts are tightened securely and in the proper location. In the situation involving enlarged screw holes, it’s advisable to put the carpenter’s glue upon a fiber plug. After plugging that in, you can check around for other various problems. Filler can help with cracks, and aside from that, you need to check to see if everything else works.

When to Perform a Garage Door Fix

Garage doors tend to last approximately 50 years when taken care of. However, most people tend to ignore their garage door’s living conditions, causing a significantly shorter lifespan. Ergo, it’s best to try to fix your garage door whenever a problem arises. Naturally, you need to figure out the costs of handling a repair on your own versus a replacement. Likewise, you need to figure out if addressing the issue on your own is the best use of time or if hiring a professional garage door installation and repair company could be more beneficial.

Other Reasons For Fixing Garage Doors

Garage doors fix one of property owners’ greatest needs, allowing an entrance between their building and the outside world. A garage door can be safe and secure, yet functionality is not the only reason to fix your garage door. Some minor reasons include, but are not limited to:

  • Testing the market’s latest springs, rollers, etc.
  • Performing regular maintenance checks
  • Trying to make a garage door to look good for visitors.

More on How to Fix

Garage door problems range from specific parts to the overall garage door itself. For example, replacing the whole garage door on your own can save you some serious dough. Keep in mind and a garage door can weigh several hundred pounds, so unless you are a bodybuilder, you should have some friends nearby to assist you.

First, you need to measure the width and length of your garage door. If you buy one of the wrong sizes, that is a complete waste of both time and money. Instead, it’s better to get one the right size for your building. Now, taking out your old garage door differs from door to door. Some can be taken down in an upright position, while others must be lowered. You can tell by the amount of tension in the spring (if there is tension, it is not safe to take it apart).

Remove the spring tension cables if there is no tension and put the garage door downwards. You need to remove some of the other attached parts, such as nuts and bolts, brackets, etc. Afterward, it would help if you got rid of the operator and safety sensors that prevent the garage door from opening and closing. After the old garage door is gotten rid of, all you need to do next is install the new one.

Several paragraphs in this article can assist you, ranging from safety sensors to openers and other minor facets such as nuts and bolts for tightening brackets. If you have somebody else helping you support the garage door’s weight, they can also help you in several operations for putting together the new garage door. Remember to take proper measurements before installing the new garage door, as different parts may have different compatibility with one another. Assuming you have all of the correct equipment, the actual installation isn’t too challenging. The main problem is that it can take an amateur several hours, so be prepared to spend around 12 hours if you have not done a similar job yet.

The main advantage is that you do not have to pay as much if you take care of it yourself.
