When your garage door starts to malfunction, it can make entering or leaving the garage a more difficult task than necessary. Typically, there are a handful of issues and problems that your garage door may be particularly likely to encounter.

Misaligned Sensors

To prevent the garage door from closing on people, vehicles or other objects, there are a series of sensors designed to detect whether something is in the path of the garage door. If these sensors become misaligned, it can prevent the door from functioning correctly as it may cause the door to detect an object in its path despite there being nothing there.  

Compromised Primary Spring

Most garage door openers will use a powerful spring to help control the heavy door. If this spring were to fail, the opener may struggle to raise or keep the door open. Corrosion can be a major cause of the primary spring failing, but it can also be necessary to replace these springs as a result of normal wear and tear. Replacing a compromised torsion spring is both extremely difficult and dangerous without the proper equipment. Homeowners should always avoid attempting to repair or replace their garage door opener's torsion spring. Incorrectly installing this spring can put it at a risk of failing when the door is in use, which may result in the spring rupturing and sending debris flying throughout the garage.

Faulty Electrical Connection

A faulty electrical connection can render a garage door either completely inoperable or it may result in the door showing unusual behaviors. Over time, the vibrations from the garage door opening and closing can cause the wiring in the opener to come loose. This may compromise the flow of electricity to the garage door, which may lead to these performance issues. One of the first steps that you may want to take to address this potential problem is to inspect and reset the circuit breaker for the door. If this fails, a professional garage door repair technician will be needed to locate the electrical problem and safely perform the correct repairs.

Lack Of Lubrication

A garage door will need ample amounts of lubrication to prevent friction damage from occurring. Fortunately, low lubrication is a problem that may provide you with some warning signs. In particular, grinding noises or the garage door working much slower than normal can indicate that the lubrication needs to be checked as soon as possible. Failing to quickly add lubrication to the opener may contribute to it being destroyed or severely damaged, which means you may want to avoid using the garage door opener until more lubrication is added to it.
