Garage Door Maintenance: What Homeowners Can Safely Check
Garage door maintenance starts with looking the door over regularly, noticing changes in how it moves or sounds, and following the door and opener manufacturer's instructions for safety testing and lubrication. You can safely observe much of the system, but springs, cables, bottom brackets and other parts under substantial tension shouldn't be adjusted or taken apart as routine maintenance.
A regular check is useful for spotting changes, wear, damage or safety concerns before you simply keep using the door. This guide is written for homeowners in Clarksville and the surrounding area, and more guides are on the Resources page.
A simple garage door maintenance routine
Step 1
Look
Look over the visible door and opener system for changes, wear or damage.
Step 2
Listen
Pay attention to new or unusual sounds during normal operation.
Step 3
Test
Follow your opener manufacturer's instructions for testing its safety features.
Step 4
Maintain safely
Follow the manufacturer's maintenance and lubrication instructions for your door and opener.
Step 5
Know when to stop
If something looks damaged, unstable, crooked, off-track or unsafe, stop and have it evaluated.
What can homeowners safely look for?
A visual inspection means looking at the system — not taking it apart or adjusting it. When it comes to cables, springs, bottom brackets and other tension-related hardware, looking does not mean touching, loosening, tightening, adjusting, disconnecting or replacing anything.
Cables
Cables that look frayed, damaged or out of place.
Track
Track that looks bent, damaged or displaced.
Panels and sections
Dents, cracks, separation or other damage to the door itself.
Rollers and hinges
Rollers or hinges that look damaged or unusually worn.
Hardware
Hardware that looks loose or visibly damaged.
The door opening
Objects, debris or clutter in the path of the door.
Safety sensors
Photo eyes that are blocked, dirty or obviously knocked out of position.
Door position
A door that looks crooked or uneven when closed or moving.
Anything new
Any other visible change from how the door normally looks.
If something looks wrong with a cable, see garage door cable repair. For bent, damaged or displaced track, see garage door track repair.
Listen and watch while the door operates
Changes in how the door normally sounds or moves can be useful warning signs. Examples include:
- Grinding or scraping
- Popping
- New squeaking
- Jerky movement or hesitation
- Unusual vibration
- Crooked or uneven movement
- Unexpected reversal
- Any noticeable change in how it normally sounds or moves
A sound on its own doesn't tell you what's wrong. But a new or persistent change is a good reason to have the door evaluated, rather than running it again and again to see whether the problem goes away. If the door has stopped moving properly, the won't open or close guide can help you understand what may be happening.
Garage door opener safety checks
Automatic openers include safety systems intended to reduce the risk of someone or something being caught under a closing door. Two are especially important:
Photoelectric safety sensors
The "photo eyes" near the bottom of the door are designed to detect something in the doorway and stop or reverse a closing door.
Automatic reversal
The opener is designed to reverse a closing door when it meets resistance or an obstruction.
Test these the way the instructions for your specific opener describe — openers differ, so there's no single test that suits every model. Never bypass or defeat a safety sensor, alter wiring or modify the opener, and only change force settings if the manufacturer's own instructions tell you to. If the opener repeatedly fails a safety test, don't ignore it — see garage door opener repair.
What about garage door lubrication?
Lubrication needs vary by door, opener and component. Follow the maintenance instructions for your specific equipment to find out what should be lubricated, which product to use and how often.
Some moving parts may need lubrication where the manufacturer specifies it, but lubrication is not the same as mechanical adjustment. Never loosen, take apart or adjust hardware in order to lubricate it. The owner's manuals for your garage door and opener are the best starting point for model-specific guidance.
How often should you check a garage door?
Industry safety guidance from DASMA recommends making visual inspection and opener safety testing a regular habit, with monthly checks. Lubrication and other maintenance requirements vary by equipment, so the instructions for your particular door and opener should set those intervals.
Regularly, such as monthly
Look the system over and run the opener manufacturer's prescribed safety tests.
As the manufacturer specifies
Lubrication and other equipment-specific maintenance.
Whenever something changes
Have unusual operation, visible damage or a failed safety test looked at, rather than assuming routine maintenance will fix it.
Maintenance vs. repair
Routine homeowner maintenance may include…
- Looking the system over
- Keeping the door's operating area clear
- Noticing changes in sound or movement
- Safety testing as the opener manufacturer prescribes
- Lubrication as the manufacturer prescribes
- Consulting the owner's manuals
A repair problem may include…
- A broken spring
- A visibly damaged or frayed cable
- A crooked or off-track door
- Damaged or displaced track
- Significant door or panel damage
- A persistent opener malfunction
- A failed safety system
- A door that is unstable or can't operate normally
Maintenance is not a substitute for repairing a damaged part. If a check turns up something on the right-hand list, see garage door repair, or spring repair if a spring looks broken.
When should you stop using the door?
Continuing to operate the door may not be appropriate when:
- The door is visibly crooked or off-track
- A spring appears broken
- A cable appears damaged or loose
- The door seems unstable
- There is significant physical damage
- Operating it causes severe binding or abnormal movement
- It's stuck open and creates a security or safety concern
- The opener's safety system isn't working as expected
Not every minor noise is an emergency. But if the door is stuck open, unstable or unsafe, see emergency garage door repair, and calling is usually the quickest way to explain the situation.
Don't Adjust High-Tension Garage Door Parts Yourself
Garage door springs, cables, bottom brackets and some related hardware can be under substantial tension. Don't loosen them, adjust spring tension, remove springs, repair or replace cables, loosen bottom brackets, or take apart any tension-loaded hardware. Spotting a problem during a maintenance check doesn't mean you should fix it yourself — see spring repair and cable repair for what a trained garage door technician typically handles.
A quick homeowner checklist
- Review the door and opener owner's manuals.
- Look for visible changes, wear or damage.
- Pay attention to new sounds or movement.
- Keep the door opening and safety-sensor area clear.
- Perform the opener manufacturer's prescribed safety tests.
- Follow manufacturer instructions for lubrication.
- Do not adjust springs, cables or bottom brackets.
- Stop and seek help when the door looks damaged, unstable or unsafe.
Frequently asked questions
How often should I check my garage door?
Industry safety guidance recommends a regular routine, with monthly visual inspection and opener safety testing. Lubrication and other equipment-specific maintenance should follow the instructions for your particular door and opener, because requirements vary.
What parts of a garage door should be lubricated?
It depends on the door, the opener and the component. The manufacturer's instructions for your equipment should identify which parts to lubricate, what product to use and how often. There is no single schedule or product that suits every door.
Can I adjust a garage door spring as part of maintenance?
No. Spring adjustment is not routine homeowner maintenance. The spring system can be under substantial tension, so adjusting, loosening or removing springs should be left to a trained garage door technician.
Why is my garage door suddenly making more noise?
New noise can come from several different components or conditions, so it can't be diagnosed from the sound alone. Consider it together with any change in how the door moves or operates, and have it evaluated if the change persists or the door isn't moving normally.
What should I do if my garage door looks crooked or off-track?
Don't force the door or keep operating it to see whether it corrects itself. Leave it where it is, keep people and vehicles clear, and have it evaluated. A crooked or off-track door is a repair problem rather than a maintenance task.
When does garage door maintenance become a repair issue?
When a check turns up visible damage, a failed safety feature, unstable or abnormal operation, or a failed component such as a broken spring or damaged cable. At that point the problem has moved beyond ordinary routine maintenance.
For a crooked or off-track door, see garage door track repair.
