How to Diagnose and Repair The Garage Door


Most homeowners don’t pay a lot of attention to their garage doors daily, as long as it’s doing its job properly. But, as momentarily as there’s a sign of trouble, all eyes shift towards its various components. Usually, this might be a good time to call up a repair professional/technician to check and fix your garage door problems. Still, before enlisting a professional’s help, there are specific minor issues one might be able to fix on their own. Following are some common garage door problems and their repair solutions that any average joe can easily do!

Remote/Keypad Not Working

You have a range of possible solutions if your opener isn’t responding to the external keypad or remote control. Perhaps the antenna in the garage is too far out of range. In that case, try moving a little closer. Consider your garage door opener as a radio with a 315mH operational range. Therefore, they can get disrupted even with 1-2 feet of extra distance. 

Also, check the motor unit’s antenna for any signs of damage and ensure it’s hung in a downward position.

Check if the wall switch can work the door. If so, then the mounted keypad or remote control requires new batteries.

Given their sensitivity, sometimes the remote control or keypad components might experience programming issues that require a reset. Try reprogramming your door opener. Different garage door openers might have differing reprogramming methods. That’s why it’s better to check the details for your specific opener first, whether on the instruction manual or online. If the process gets too overwhelming, you can always hire experienced professionals to install a new one. Suppose you are residing near southwestern Utah. In that case, you can hire someone skilled for Garage Door Installation St George UT. It will ease some burden off your shoulders.

Faulty Cables

Broken cables are another common issue concerning garage doors. The underlying reasons can range from extra pressure caused by broken springs to regular wear and tear. If you notice slight sagging or heaviness on either side of the door, know there’s a broken cable.

The garage door will also be angled downwards and leaning more on one side if that happens. Additionally, the door might not stay in one place if all the cables have come loose. Be careful when that happens, as it might come down when you try to lift it. It’s better to deal with faulty cables at the earliest as they pose severe safety hazards.

Door Doesn’t Close Completely 

Is your garage door opening fine but doesn’t close all the way? One of the following causes might be the culprit behind this issue.

Firstly, check if you need to adjust your set-limit switch. Garage doors consist of close-limit switches that facilitate starting and stopping of the motor as the door opens/closes. When set incorrectly, this switch can prevent the door from closing. Plus, it can lead to the opener reversing when you’re trying to close the door. Depending on the type of door, there can be various approaches for adjusting the set-limit switches. Still, most doors feature a screw on the motor unit that can easily adjust to control the speed of the door’s descent.

Secondly, you may need to realign or adjust the sensors. On both sides, right at the bottom of the door track, are electronic sensors that require a clear line of sight between them. The door will close smoothly without any trouble, given the sight path between the sensors is crystal clear. But, if something is blocking the sensors’ line of view, it can prevent your door from closing down. Besides the eyes, your door can also malfunction if the brackets holding the electronic eyes are misaligned. Fortunately, in such scenarios, the door itself reverses or halts, flashing its lights to indicate a problem. 

So, check and remove any hindrances that may be blocking the sight path between the sensors, such as leaves, dirt, and debris. However, suppose this issue is a frequent occurrence. In that case, the sensor brackets might get loosened from vibrations coming from the door tracks and need realigning. 

Door Closes But Immediately Reopens

This problem’s diagnosis is quite simple; you have to adjust your garage door opener. Most automatic garage door openers have settings for controlling the open and close functions. And occasionally, they might require adjustments, owing to daily usage and wear and tear.

The limit settings can dictate how far the moves to be fully closed or opened. Suppose these settings are off. In such cases, when the door reaches the floor, the opener’s sensors will signal this as hitting an object/person rather than the ground. Hence, the door will reopen.

Door Does Not Open All The Way

Periodically, the garage door may ascend correctly but won’t open entirely. Following causes might be the culprits behind such issues.

You need to move the up-limit switch closer to your door’s motor unit. An up-limit switch is a touch lever perched on the hinges near the motor unit. When it sits too far away, the motor will limit the door from opening fully. What’s the solution? Simply move this switch a little closer to the motor unit. This issue rarely occurs. But when it does, it’s usually after a new door opener installation. 

What’s more, damaged or sticky rollers can also stop the garage door short from fully opening. Check your rollers for any damage, dust-up, lubricate, or replace if they’re too damaged.

Jammed Rollers

If you find that the rollers on your garage door’s sides are sticking and sliding instead of spinning and turning, as they should, you’re in trouble. Why? This problem can lead to the door coming entirely off its hinges. Plus, jammed rollers can cause unnecessary noise during the opening and closing of the door.

It’s better to leave the door as is if it comes off of its tracks during opening or closing. Any attempts to change the open or closed position could potentially cause the springs and cables to break. And if noisiness is the only issue, try cleaning the tracks or replacing the rollers if possible. More often than not, humidity and lack of lubrication are the leading causes behind stuck rollers.
