Does your garage door look uneven when opening or closing? Is one side sitting higher than the other? Or does the door suddenly feel heavy, move awkwardly or struggle to stay in position?
These are common signs of an unbalanced garage door.
At Mann Garage Door Services, we regularly attend garage door repair jobs across Perth where the door has become uneven or fallen out of balance. While the problem can sometimes look like a simple alignment issue, the actual cause may be somewhere within the spring, cable, roller, track or lifting system.
Recently, we attended another garage door repair job involving a door that was no longer operating evenly. Here’s a closer look at what can cause this problem, why it shouldn’t be ignored and how a professional garage door technician can get the system operating smoothly again.
What Is an Unbalanced Garage Door?
A garage door is much heavier than it may appear. Springs and cables work together to counterbalance its weight, allowing the door to move smoothly while reducing the amount of work required from the garage door opener.
When that balance is disturbed, the door may no longer travel evenly.
Depending on the fault, you might notice the door leaning towards one side, lifting unevenly, becoming unusually heavy or moving with a jerking motion.
Some homeowners describe this as a disbalanced garage door, while others search for terms such as:
-
Garage door out of balance
-
Uneven garage door
-
Crooked garage door
-
Garage door not level
-
Garage door lifting on one side
-
Garage door realignment
-
Garage door leaning to one side
Although the symptoms can look similar, there isn’t one single component responsible for every unbalanced garage door. The complete lifting system needs to be inspected to identify the underlying cause.
What Causes a Garage Door to Become Unbalanced?
Several mechanical problems can cause a garage door to lose its proper balance.
1. Incorrect or Uneven Spring Tension
Garage door springs counterbalance much of the weight of the door.
As springs wear or their tension changes, the door may become harder to lift or may no longer remain in the correct position. If the spring system is not providing the correct counterbalance, the garage door opener can also be forced to work harder than it should.
Spring adjustment is not a DIY repair. Garage door springs operate under significant tension and should only be inspected and adjusted by someone with appropriate experience and equipment.
2. Garage Door Cable Problems
The lifting cables on each side of the door need to operate correctly and maintain appropriate tension.
A cable that has become loose, frayed, damaged or displaced from its drum can cause one side of the garage door to behave differently from the other.
A common symptom is a door that begins lifting on one side while the opposite side remains lower.
If your garage door is visibly crooked, stop repeatedly operating it and have the cables and lifting system inspected.
3. Cable Drum Issues
On many sectional garage doors, cables wind around drums as the door moves.
If a cable is not sitting or winding correctly on its drum, the door may travel unevenly. Continuing to operate the door in this condition can potentially create additional problems with the cable, track or other components.
4. Worn or Damaged Rollers
Garage door rollers help guide the door along its tracks.
A worn, seized or damaged roller can create additional resistance on one side of the door. Instead of moving freely, the affected side may drag or jerk as the garage door opens and closes.
Roller condition should therefore be checked when diagnosing an uneven garage door.
5. Bent or Misaligned Tracks
The tracks need to provide a clear and properly aligned path for the rollers.
A bent, damaged or incorrectly aligned track can cause the garage door to bind or move inconsistently. This can sometimes make a balance problem appear worse or produce similar symptoms.
6. Worn Hinges or Loose Hardware
Garage doors contain numerous hinges, brackets and fasteners that work together every time the door opens.
With regular use, components can wear or hardware can loosen. These seemingly small issues can affect how the panels move through the tracks and should be checked as part of a complete inspection.
7. Previous Incorrect Repairs
Garage door balance can also be affected by incorrect spring tension, mismatched components or repairs that have not addressed the original cause of the problem.
This is why simply adjusting the part that appears crooked isn’t always enough. The complete door system needs to be considered.
Signs Your Garage Door May Be Out of Balance
An unbalanced garage door does not always fail completely. In many cases, the warning signs appear gradually.
You may notice:
-
One side of the garage door sits higher than the other
-
The door looks crooked while opening or closing
-
One side starts moving before the other
-
The door feels unusually heavy
-
The door opens or closes with jerky movements
-
The garage door suddenly drops when operated manually
-
The door rises when it should remain stationary
-
Cables appear loose or uneven
-
The opener sounds like it is struggling
-
The door makes new grinding, scraping or banging noises
-
The door catches at a particular point during operation
If your garage door is showing these symptoms, it is worth having the problem investigated before continued operation causes additional damage.
Why You Shouldn’t Ignore an Unbalanced Garage Door
An uneven garage door isn’t only an appearance problem.
Your garage door is a large moving system consisting of springs, cables, tracks, rollers, hinges, brackets and an electric opener. These components are designed to work together.
When the door becomes unbalanced, additional load can be transferred to other parts of the system.
Extra Stress on the Garage Door Opener
The garage door opener works best when connected to a properly balanced door.
If the door becomes excessively heavy or difficult to move, the motor may have to work harder during every opening and closing cycle.
Fixing the balance problem early may therefore help prevent unnecessary strain on the opener.
Additional Wear on Cables and Hardware
If one side of the door is carrying more load than the other, cables, rollers and other hardware may experience uneven stress.
What begins as an alignment or balance problem can eventually develop into a more complicated garage door repair.
Potential Safety Risk
A severely unbalanced door may move unexpectedly or become difficult to control.
If a spring or cable is damaged, homeowners should avoid attempting their own adjustments. These components can be under substantial tension and require appropriate tools and repair procedures.
How We Diagnose an Unbalanced Garage Door
At Mann Garage Door Services, we don’t want to simply make the door look straight and leave the underlying problem unresolved.
The objective is to determine why the garage door became unbalanced in the first place.
Depending on the door and symptoms, an inspection may include checking:
-
Garage door balance
-
Spring condition and tension
-
Lift cables
-
Cable drums
-
Rollers
-
Tracks
-
Hinges
-
Brackets and fasteners
-
Door panels
-
Garage door opener operation
-
General movement of the door
Once the cause has been identified, the appropriate repair or adjustment can be carried out.
Repairing and Rebalancing the Garage Door
The exact repair required depends on what has caused the imbalance.
A garage door balance repair may involve correcting spring tension, addressing cable or drum problems, replacing worn rollers, correcting track alignment, tightening or replacing hardware, or repairing another component affecting the movement of the door.
After the required work has been completed, the door should be tested through its operating cycle to make sure it travels smoothly and evenly.
The opener operation and relevant safety functions should also be checked before the job is considered complete.
Can You Balance a Garage Door Yourself?
Basic visual checks can help you identify that something isn’t right, but homeowners should be particularly cautious around springs and cables.
Never attempt to wind or unwind garage door springs, loosen cable drums, remove bottom brackets or re-tension lifting cables unless you have the appropriate training and equipment.
These components can store considerable energy.
If the garage door is already sitting badly crooked, a cable is hanging loose, a spring appears broken or the door feels extremely heavy, the safer option is to stop using the door and arrange a professional inspection.
Don’t Assume the Garage Door Motor Is the Problem
This is an important point.
When an automatic garage door starts struggling to open, it can be tempting to assume the motor is failing.
But sometimes the opener is simply reacting to a mechanical problem elsewhere in the door.
If the spring system is no longer properly counterbalancing the door, or a roller, cable or track is creating resistance, replacing the motor alone will not address the underlying issue.
The mechanical operation and balance of the garage door should therefore be checked before concluding that a struggling opener needs replacement.
