Why does the Garage Door open partially Then Stops? | How Can I fix it?

Share

It can be incredibly frustrating when you press the button to open your garage door, only to have it start opening and then stop partway. There are several possible reasons why your garage door is opens partially then stops. Understanding the most common causes can help you troubleshoot the issue and get your garage door working properly again.

Common Reasons Garage Door opens partially Then Stops

There are a few common things that can cause a garage door opens a little and then stop:

Obstruction

One of the most common reasons a garage door will only opens part way is because there is some kind of obstruction in the way. This could be something inside the garage like a bicycle, ladder, or other items that are blocking the door’s path. It could also be something outside like a branch, debris, or even an accumulation of snow or ice.

If there is something obstructing the garage door’s opening path, the door will hit that obstruction and stop when trying to open all the way. You’ll want to thoroughly inspect the full range of motion of the door and remove anything that could be preventing the door from fully opening.

Broken Spring

The torsion springs on garage doors play a critical role in counterbalancing the weight of the door to allow it to open and close smoothly. However, garage door springs wear out over time. A broken garage door spring prevents the door from opening all the way, because the spring assembly is not working.

When a torsion spring breaks, the door loses the counterbalance force needed to fully open. This causes the garage door to partially open then stop when the opener runs into resistance from the imbalance. May need to replace the door spring is the only way to fix this issue and allow normal operation.

Improperly Adjusted Garage Door Opener

Another possibility is that the garage door opener force or limit settings need adjustment. The force adjustment controls the amount of power the opener motor applies to open and close the door. If this is set too low, the opener won’t have enough force to lift the full weight of the door, resulting in the door only opening partially before stopping.

The limit settings control how far down and up the door will travel. If either the open or close limit is set incorrectly, this restricts how far the door can move in that direction. For example, if the open limit is set too low, the door will hit the limit and stop before reaching the fully open position. Adjusting the force and limit settings correctly should allow full travel.

Malfunctioning Garage Door Sensor

Safety sensors are an important component for garage door openers. These sensors project invisible beams across the doorway and signal the opener to stop and reverse if something breaks the beam while the door is closing. However, problems with misaligned sensors or sensor malfunctions can also cause issues with opening.

If the sensors are obstructed or knocked out of alignment, the opener may misread that as an obstruction and stop the door while it’s opening. Inspect the sensors to make sure they are clean, aligned properly, and operating correctly. Realigning or replacing faulty sensors can get your garage door opening fully again.

Travel Limit Issue

In addition to force limits, most garage door openers have travel limits that control how far up or down the door will move. If the travel limit that controls how far the door can open is mistakenly set too low, it will prevent the door from fully opening.

This limit setting needs to be adjusted upward to allow the needed door travel to open completely. Refer to your garage door opener manual to learn how to adjust the open travel limit to match the height your door needs to fully open.

Weather-related Factors

Outdoor temperature fluctuations and weather events can also impact garage door operation and cause a door to only open partially before stopping.

Cold Weather Effects

In cold weather, the contraction of garage door components due to shrinking in frigid temperatures can cause issues with opening. The metal parts of the door and opener can contract and tighten up, increasing friction and resistance as the door tries to open.

Lubricating rollers, hinges, pulleys, and tracks can help combat the increased friction from cold temperatures. But extreme cold causes more significant interference and may prevent the door from fully opening until temperatures warm up again. Operating an obstructed door in cold weather can also overload and damage opener parts.

Force Limit Adjustments in Cold Weather

Many garage door openers have a separate cold weather or winter force setting. This increases the opener motor’s power to account for the increased resistance from extreme cold.

If your opener has this feature, adjusting the force limit to the higher cold weather setting may provide the extra boost needed to overcome the increased friction and open the door fully. Whenever temperatures return to normal, be sure to switch the force back to standard mode.

Garage Door Components

When troubleshooting a garage door that only opens partially, it helps to understand the basic components and operation of the door. Here are the main parts that work together to open and close the door:

Garage Door Opener

The opener consists of a motorized unit with a rail, trolley, and arm that connects to the top of the door. The motor provides the lifting force to open and close the heavy door. If the opener motor is underpowered or there are issues with the mechanism, it can cause problems with door travel.

Garage Door Springs

Garage Door Springs

Torsion springs are mounted on a metal shaft running above the door. The tension of these springs helps lift the weight of the door, offsetting the door’s weight to allow smooth operation. Broken or damaged springs will prevent the door from opening fully.

Garage Door Tracks

Rollers on the sides of the door move along vertical and horizontal tracks to guide the door up and down. Bent, misaligned, or obstructed tracks can restrict the travel and cause the door to bind up when opening or closing.

Proper installation and alignment of these components is needed for the door to move through its full operating range without obstruction. Now let’s look at the steps for inspecting and adjusting these parts of the garage door system.

Steps to Fix a Garage Door Only Opening Partially

If your garage door is opening a few feet or part way then stopping, here are some steps you can take to diagnose and fix the issue:

Inspect the Garage Door

The first step is to visually inspect the door to see if you can spot any obvious problems. Look at the door panels and hardware. Are there any broken, damaged, or loose parts? Are the door panels dented or warped? Any separated or cracked areas?

A damaged panel or hardware that is causing an obstruction could be preventing the door from making its full upward travel. If you spot any damage, try lifting the door manually to isolate the problem area. The inspection can help narrow down the cause.

Check for Obstructions

With the garage door closed, visually inspect the surrounding driveway, walls, tracks, springs, and opener hardware. Look for anything that sticks out or is in the path of the door that it could be hitting against during operation.

Obstructions like ladders, landscape debris, trash cans, bikes, tree branches, or accumulated ice/snow can all stop the door prematurely. Clear any obstructions that are in the way of the door’s range of motion.

Test the Door Manually

After removing any obstructions, disengage the opener by pulling the manual release handle. This will allow you to manually lift the door without resistance from the opener.

Gently lift the door about halfway up and see if you can easily manually raise it fully open and closed. If the door opens fully with no problems manually, it points to an issue with the opener or counterbalance system rather than binding or obstructions.

Adjust the Garage Door Opener

If the door operates fine manually, check the opener force and limit adjustments next. The force setting determines the amount of power applied by the motor. Start by setting this to maximum.

The limit adjustment sets how far the opener will open the door before stopping. Loosen the opening limit adjustment screw and slide the limiter bar farther out so it will allow full upward travel of the door if needed.

Run the opener through a full cycle and see if adjusting these settings allows the opener motor to lift the door completely without stopping partway. Make sure to reset the force back to standard mode once it is opening properly.

Inspect Garage Door Springs

It’s very common for old, worn torsion springs to break, preventing the door from opening more than a few feet before stopping.

Check the condition of the torsion springs above the closed door. Closely inspect for any broken or separated coils, cracks, or torsion shaft displacement which are all indications of broken springs. If you suspect the springs are broken, contact a garage door professional to replace the springs before using the door further to prevent damage or injury.

Check Garage Door Tracks

With the door closed, examine the vertical tracks on both sides. Make sure the tracks are straight with no kinks or bends. The tracks should be clear of debris and the rollers inside should spin freely without resistance or hang ups.

Then open the door manually about halfway and check that the horizontal tracks are straight and level. Door track problems can cause binding that prevents smooth operation. If the tracks are crooked or have obstructions, try straightening or clearing them.

Test the Garage Door Sensor

Malfunctioning safety sensors are a common cause for a garage door only opening a few feet before reversing. The sensors are located near the bottom of the door opening.

Start by visually checking that both sensors are aligned correctly. The lenses should point directly at each other without any obstruction in between. Then test the door sensor by blocking one of the sensor beams while operating the door. The opener should stop and reverse direction when the beam is interrupted.

If the sensors are dirty, misaligned or non-responsive, clean and realign them. Replace batteries if needed. Fixing sensor issues can allow the door to open fully without automatically stopping and reversing.

When to Call a Garage Door Technician

If you’ve tried all of the DIY troubleshooting steps and your garage door still only opens partially before stopping, it’s probably time to call a professional. The following are signs you may need garage door repair services:
