Common Problems with Garage Door Closing Slowly — How to Fix

/wp:heading wp:paragraph

There are a number of issues that can cause a garage door to close slower than it should. The most common causes include:

/wp:paragraph wp:heading {"level":3}

Lack of Proper Lubrication

/wp:heading wp:image {"id":4291,"width":"292px","height":"auto","aspectRatio":"1","sizeSlug":"full","linkDestination":"none","align":"right"}

/wp:image wp:paragraph

Garage doors have many metal parts like rollers, hinges, and springs that rotate and slide against each other during operation. Without proper lubrication, the metal-on-metal friction will lead to binding and drag that slows the door. This added resistance makes the opener work much harder to close the door.

/wp:paragraph wp:paragraph

Inspect all moving components and apply garage door lubricant to any areas that appear dry. Pay particular attention to the rollers and hinges. Lubricating twice per year is recommended for preventing slow closure issues. Any squeaks or grinding noises are a sign that lubrication is overdue.

Worn or Damaged Rollers

/wp:heading wp:paragraph

The small wheels that run along the door’s tracks are called rollers. With frequent use, these rollers gradually wear down and develop flat spots. A damaged roller will scrape and drag along the track rather than roll smoothly. This halts the door’s momentum and makes the opener struggle to close it.

/wp:paragraph wp:paragraph

Check rollers for any visible damage or oblong shapes. Spin each roller to feel for rough rotation. Replace any deteriorated rollers immediately before they cause further damage to the track. Installing high quality nylon or steel replacement rollers can help the door close smoothly for years.

/wp:paragraph wp:heading {"level":3}

Misaligned or Damaged Tracks

/wp:heading wp:paragraph

If the metal tracks that guide the rollers become bent or misaligned, it can cause significant resistance and friction for the door to overcome. The rollers will bind in the warped areas of track rather than moving freely. Tracks can become knocked out of alignment by impact or natural settling of the building.

/wp:paragraph wp:paragraph

Inspect tracks for dents, kinks, and any sections that are no longer straight and flat. Track alignment needs to be precise for proper roller movement. Contact a professional garage door technician to have misaligned tracks straightened or replaced.

Tension Issues with Springs and Cables

/wp:heading wp:paragraph

Garage door springs produce the counterbalance tension needed to offset the door’s weight. This allows the door to open and close smoothly. If the springs have the wrong tension, the door will seem heavy and resist normal operation. Weak or broken springs will cause very slow closure. The lifting cables can also lose proper tension and cause similar issues.

/wp:paragraph wp:paragraph

Inspect the springs and cables closely. Signs of a tension problem include door drifting down when partially open, jerky movement, binding, and taking longer to open or close. The springs and hardware are under extreme tension and adjustments should only be made by a trained professional to avoid injury. Complete spring or cable replacement may be needed.

/wp:paragraph wp:heading {"level":3}

Worn-Out Hinges

/wp:heading wp:paragraph

Steel hinges connect each door section and allow articulation as the door moves. While robust, hinges do wear out over time, especially if not regularly lubricated. Worn-out hinges that are loose or sagging will prevent the door from closing smoothly and with proper alignment.

/wp:paragraph wp:paragraph

Check all hinges along the width and height of the door. Look for hinges that appear deformed or have lost their flush fit. Any that are loose or moving erratically need to be tightened or replaced. This will realign the door sections and remove drag points.

/wp:paragraph wp:heading {"level":3}

Opener Problems

/wp:heading wp:paragraph

If an automatic opener is used to operate the door, problems with the opener itself can also cause slow closing. Low power, mechanical issues, and problems with the wall-mounted button or remote can prevent the opener from closing the door properly. Opener motors gradually lose torque over years of use as well.

/wp:paragraph wp:paragraph

Check that the opener has power and is responsive to the button or remote. Most openers have a force or speed adjustment that may need increased. Listen and watch for any straining or abnormal movements during operation. Have a garage door technician inspect the opener components and make repairs as needed. Installing a brand new opener is an option if the current model is outdated or underpowered.

/wp:paragraph wp:heading {"level":3}

Issues with Closing Force Adjustment

/wp:heading wp:paragraph

Automatic garage door openers have a force adjustment that controls the amount of power applied during closing and opening. If this closer force setting is too low, the motor will have trouble overcoming friction to close the door. Turning the force adjustment to a higher setting can resolve this.

/wp:paragraph wp:paragraph

Locate the adjustable force dial on the opener and incrementally increase the force setting until the door consistently closes without issue. Be careful not to set the force too high, as this can damage the door and create a safety hazard. Finding the ideal force level may take some trial and error. Consult the opener manufacturer’s recommendations.

/wp:paragraph wp:heading {"level":3}

Weather Stripping in Poor Condition

/wp:heading wp:paragraph

Weather seals are installed around garage door perimeters to block out wind, rain, dust and other outdoor elements. If the weather stripping has become brittle, torn or detached, it allows air to enter the garage and create added resistance against the door closing.

/wp:paragraph wp:paragraph

Inspect weather seals on the top, bottom and sides of the door. Check for cracking, gaps or missing sections. Compressed seals that no longer spring back may also need replacement. Install new weather stripping designed for garage doors to restore a tight perimeter seal when closed.

Accumulation of Debris and Dirt

/wp:heading wp:image {"id":4293,"width":"292px","aspectRatio":"1","scale":"cover","sizeSlug":"full","linkDestination":"none","align":"right"}

/wp:image wp:paragraph

Over time, debris like dust and dirt can collect in garage door tracks and moving components. This buildup leads to gritty friction as the rollers move through the tracks. Any debris that gets lodged inside hinges or springs can also impede normal operation and make doors close slower.

/wp:paragraph wp:paragraph

Use a vacuum and rag to thoroughly clean garage door tracks, removing all built up debris inside. Blow out or dislodge any dirt that has collected inside hinges, rollers and springs. Following a regular maintenance routine will prevent major buildups in the future. If dirt and sand are getting blown into the garage frequently, consider sealing any cracks or gaps that allow infiltration.

Electrical Problems with Sensors or Wiring

/wp:heading wp:image {"id":4295,"width":"292px","sizeSlug":"full","linkDestination":"none","align":"right"}

/wp:image wp:paragraph

Automatic garage door openers rely on electric sensors that detect objects obstructing the door. If something is blocking the photo eye beam or motion sensor during closure, the door will reverse open. Any electrical issues with the sensors or opener wiring can also cause unintended reversal or stoppage that prevents proper closing.

/wp:paragraph wp:paragraph

Check for loose sensor brackets, malfunctioning sensors, cobwebs blocking the sensors, and any damaged wires. Address sensors that appear askew or have blinking lights indicating signal problems. Repair or replace damaged wires. Thoroughly cleaning sensors and realigning brackets often resolves closure issues. Have an opener technician assess electrical components for other problems.

Here are some tips to keep your garage door closing properly for years to come:

/wp:paragraph wp:list

• Lubricate the rollers, bearings and hinges - Twice yearly lubrication is the easiest way to combat friction and maintain smooth operation.
• Inspect hardware regularly - Look for signs of wear yearly and replace rollers, cables and hinges as needed.
• Clean tracks seasonally - Remove debris before it builds up and clogs the track system.
• Check weather seals and replace if damaged - This prevents wind resistance and outside elements from entering the garage.
• Test door balance yearly - Adjust spring tension and cable tautness to offset door weight.
• Have opener serviced if needed - Update old openers and keep tuned up to ensure proper closing force.
• Listen for noises and binding - These are the warning signs of underlying issues that require correction.
• Watch for alignment problems - If one side of the door lags, realign the tracks.
• Adjust opener force properly - Setting too low makes closure difficult, too high risks equipment damage.

• Lubricate the moving metal parts like hinges and rollers a few times per year using a garage door lubricant.
• Inspect hardware components for signs of wear regularly and replace as needed. Rollers are most prone to wear.
• Make sure tracks are aligned properly and free of debris, dust, rocks, etc.
• Check cables, springs and opener settings to ensure proper tension and force.
• Clean weather stripping and replace if worn to prevent air resistance.
• Address any grinding, squeaking noises right away before it worsens.
• Have a professional garage door tune-up to check balance, alignment and condition annually.
