Why Does My Garage Door Get Stuck When Opening/Closing?


Automatic garage doors are a true convenience when they work properly, but when they don’t, they become a frustrating hassle. Like all mechanical devices, garage doors and their openers are prone to faults that can prevent them from opening and closing like they’re supposed to. Here are some of the reasons why this might happen.

Lack of Lubrication

Your garage door’s track and the opener’s chain both require sufficient lubrication in order to do their jobs. If either one is under-lubed, the door can become stuck when opening or closing. To fix this problem, you will need to add more lubrication to both parts. You can use a standard machine oil either in a spray can or a bottle. However, the spray option will be much simpler to use, especially at odd angles.

Damage to the Track

Most garage doors sit in a track made from aluminum, which is highly susceptible to warping and bending. Impacts from tools, ladders, cars or other objects can bend the track in such a way that the door is unable to open or close fully. Similarly, the freezing and thawing process of winter weather can cause the frame to become distorted and make the door jam. Depending on the location and severity of the damage, you may be able to repair the track without professional assistance or a new installation. Try using a hammer to pop out any dents.

Sensor Problems

All modern electric garage door openers are required by law to come equipped with sensors for safety purposes. These are typically located on either side of the garage door near the ground. If something gets in the way, like a child or a pet, the sensors will prevent the door from opening or closing. While this feature is indisputably beneficial, it is unable discriminate between living things and inanimate objects. If your door is becoming stuck, make sure that there are no leaves or other debris piled in front of the sensors and keep the items stored in your garage clear of them.

Faulty Sensor Alignment

In order to work as intended, the sensors on either side of your garage door must be properly aligned. If the infrared beams fail to make contact with one another, the door will refuse to budge. However, it can be very tricky to tell whether or not they are aligned correctly. If you suspect that this is your problem, it is strongly recommended that you have a professional garage door technician determine if it is the case and make adjustments as necessary.
