Why Won’t My Garage Door Close? (11 Reasons Why)

Garage doors can be a pain to operate. You might try to lift the door manually, but if it’s raining or something is blocking the way, that won’t work.

Even so, your garage door should open and close on its own automatically. So what’s going on when the door doesn’t completely close? Here’s what I will give to light about why your garage door won’t close!

Why Won’t My Garage Door Close?

1. No Electricity

If you have ever had this problem, you know that you need to check your electrical system. You may not even realize it, but your garage door battery could be low or dead.

Furthermore, it can happen when you let your battery run down because you forgot to recharge it or never plugged it in.

Moreover, if it occurs, there’s nothing wrong with your door—it needs an extra power boost to get it moving again.

As a result, if you have no electricity in your home, it’s possible that the door will not open or close because there is no voltage being sent to the motor!

2. Defective Sensors

Only if the sensor is functioning correctly will the garage door close. If the sensor is broken, your opener won’t work and won’t send a signal to open for you.

Along with this, if your springs or cables are damaged or worn out, you can potentially have a problem. These components need to be replaced before they suffer irreparable damage.

Because of that, for the sensors to receive a clean signal from the outside, you also need to ensure that they are free of any obstructions.

As an effect, the sensor should be inspected for any signs of damage and any loose connections that might have contributed to the failure!

3. Obstructed Door

An obstruction is the most frequent cause of a garage door that won’t shut. It could be anything from twigs and leaves to shattered pieces of accumulated material in the rails.

As well as that, rocks, dirt, grime, and even dust can assemble and obstruct the passage of the garage door.

Overall, your garage door won’t close correctly if leaves or other debris are stuck in the tracks and they aren’t periodically wiped out!

4. Automatic Override Glitch

If your garage door doesn’t close, there might be a problem with your automatic override.

Therefore, checking the safety sensors to see whether they are functioning correctly if you have this issue is recommended.

On that account, if the garage door doesn’t close, check to see if your garage door is experiencing some override glitch!

5. Locked Door

A common problem is a stuck garage door. Hence, the bottom rail is obstructed, and it appears like nothing is operating.

As such, lubrication helps the chain move more smoothly and efficiently. Additionally, if you have heavy snow or ice on your driveway, this can also cause problems.

On the grounds of this, it’s essential to keep your garage door in good condition so that it functions appropriately and safely, preventing your garage door from hooking!

6. Door Track Dilemma

Door Track Dilemma

Over time your metal tracks may rust, twist, or bend, jeopardizing the security of your garage door system. If the garage has been busted over age, it’s usually time to replace the tracks.

On the contrary, garage door motion and door closure may be hampered by a track that appears broken or misaligned.

This is why it’s possible that the track door is broken or anything is blocking its path, preventing you from shutting the garage door!

7. Goes Out Of Alignment

An incorrect height alignment is the most frequent cause of the garage door failing to close.

Because of this, the springs and wires are intended to act as a single unit. Therefore, if the cables are out of alignment, the door will not operate on its own.

Above all, if they are out of place, the door may pop open while it should be closing!

8. Fragmented Cables And Springs

If the torsion spring in your garage door is broken, you’ll probably notice that the automatic garage door opener won’t work in this situation.

In that case, the door won’t remain in the up position when you raise it manually after disconnecting the opener. Viewing it in the spring will reveal the split.

For this reason, it is advised to double-check damaged garage door springs and line wires so you can immediately tell if they are busted!

9. Worn Gear Teeth

Despite being an electronic device, your garage door opener still contains manual components.

Moreover, the device’s plastic or nylon gears are used to move the door physically.

Furthermore, your gears will deteriorate if the grease dries up, so an unbalanced garage door is another factor in worn opener gears.

To such a degree, the garage door cannot be moved because the gears cannot lock together!

10. Obstruction On Track And Tension Spring

To check for this condition, lift the garage door up and down with a hand truck or car jack to see if it moves freely.

Following that, if it does not move freely, the obstruction could be something as simple as dirt or debris that has gotten in between the rollers and the track itself.

That is why, if there is an obstruction on the track, it can stop your garage door from closing completely!

11. Sensor Misalignment

Photo-eye sensors readily pushed out of alignment will be used in the door system.

Additionally, it would interfere with the mechanism’s capacity to operate as intended. Therefore, both sensors should have lights, and they should be lighted.

In that case, if your garage door won’t close all the way, it’s likely because there is a misalignment between your sensor and its mounting bracket on the wall above it!

One of the most crucial components of your house is likely your garage door.

Numerous things, such as a lack of electricity, faulty sensors, and a blocked door, can contribute to this.

Above all, maintaining it properly and efficiently is a terrific way to save your items, conserve space, and increase the value of your home!
