Why Won't My Garage Door Close All The Way

“Why won’t my garage door close all the way?” If you’ve found yourself pondering this frustrating question, you’re not alone. Dealing with a garage door that refuses to close completely can be both inconvenient and worrisome.

Not only does it compromise the security of your home and belongings, but it can also leave you feeling perplexed about the underlying cause. 

In this practical troubleshooting guide, we will delve into the possible reasons behind your garage door’s incomplete closure and provide realistic solutions to help you regain control over this essential entry point.

Let’s get started without further adieu.

Reasons Behind why won’t my garage door close all the way

There are several reasons garage doors won’t close completely. Here are some common points to consider:

Obstruction in the Doorway 

Objects or debris blocking the path of the garage door can trigger the safety sensors, and thus your garage door won’t close all the way.

Malfunctioning Safety Sensors 

If the safety sensors are damaged or worn out, they may fail to function properly, leading to issues with the door’s closing mechanism.

Issues with the Garage Door Tracks 

Bends, dents, or debris on the tracks can obstruct the smooth movement of the garage door, and your garage door does not go all the way down as a result.

Insufficient Lubrication 

Without proper lubrication, the door’s moving parts, such as rollers, hinges, and tracks, can experience friction, hindering the door’s complete closure.

Problems with the Garage Door Opener Settings 

Incorrect settings, such as travel limits, force adjustments, or downforce adjustments, can prevent the garage door from closing properly.

Damaged or Worn Springs and Cables 

The springs and cables play a crucial role in the operation of the garage door. If they are damaged or worn, they can impede the closing process, and as a result, the garage door doesn’t fully close.

Power Issues 

Power supply problems, such as a tripped circuit breaker or faulty wiring, can prevent the garage door opener from functioning correctly, causing issues with the door’s closing mechanism. Consequently, the garage door won’t close completely.

Misaligned Safety Sensors 

Safety sensors have been legally required since 1993 and play a crucial role in maintaining a safe environment around the garage door. When these sensors are not properly aligned, they may not detect the door’s movement correctly, causing it to stop before closing entirely.

How to Fix a Garage Door That Won’t Close

If you’re dealing with a garage door that won’t close, here are some step-by-step points to help you troubleshoot and fix the issue:

Check for Obstructions 

Look for any objects or debris blocking the path of the garage door. Remove any items that may be obstructing its movement.

Inspect the Safety Sensors 

Ensure that the safety sensors, located near the bottom of the door, are properly aligned and free from dirt or debris. Clean the sensors and adjust their alignment if necessary.

Test the Remote Control and Wall Switch 

Make sure the batteries in your remote control are working properly. Test the wall switch to verify that it’s functioning correctly.

Examine the Tracks 

Examine the tracks on both sides of the door for any bends, dents, or obstructions. Use a level to ensure the tracks are aligned correctly.

Lubricate Moving Parts

Apply a silicone-based lubricant to the rollers, hinges, and tracks. This will reduce friction and help the door move smoothly.

Adjust the Garage Door Opener Settings 

Consult the owner’s manual for your garage door opener and adjust the settings as needed. Look for features like travel limit adjustment, force adjustment, or downforce adjustment. Incorrect settings can prevent the door from closing properly.

Check the Springs and Cables 

Inspect the door springs and cables for any damage or wear. Broken or worn-out springs and cables can affect the door’s operation. If you come across any issues, contact a professional technician to replace them.

Test the Power Supply 

Ensure that the garage door opener is receiving power. Check the circuit breaker and verify that the power supply is stable. If necessary, call an electrician to address any electrical issues.

Reset the Garage Door Opener 

Resetting the opener may help resolve any minor glitches. Refer to the manufacturer’s instructions to learn how to reset your specific model.

Seek Professional Assistance 

If you’ve gone through these troubleshooting steps and the door still won’t close, or if you’re unsure about performing the repairs yourself, it’s recommended to contact a professional garage door technician. They have the expertise and tools to diagnose and fix more complex issues safely.

Remember, safety is paramount when working with garage doors. If at any point you feel uncomfortable or uncertain about the repair process, it’s best to seek professional help.
