5 Reasons Your Garage Door May Not Open

When you have a manual garage door, you don't have to worry about motor malfunctions, however, they can be difficult to raise and lower, especially if your have health problems such as chronic pain. While electric overhead doors make it easier to get in and out of your garage, they may malfunction. Although there are certain things you can do yourself that will restore your door to its proper working order, you may need to call a garage door repair professional to diagnose the problem. Here are five reasons your garage door may not open:

Obscured Electronic Sensor

Motorized garage doors have an electronic eye sensor that emits a laser beam across the length of your garage. If that laser is interrupted or obscured by an object such as a garbage can or dirt on the lens, the signal will be disrupted so that the motor will not be able to raise or lower the garage door. Keep items away from the lens and periodically clean the sensor with a dry, lint-free rag to remove debris that may be blocking the signal.

Faulty Torsion Springs

Broken torsion springs will prevent your electric overhead door from opening. You may even hear the spring breaking, which typically sounds similar to a firecracker. If you have broken torsion springs, never attempt to open the door.

This can further damage the motor and may even pose a danger to your safety. If you try closing a garage door that has a broken torsion spring, it may come crashing down on anyone standing in the way. Springs are commonly rated for a certain amount of cycles and are usually the first things that malfunction in garage door systems.

Snapped Cables

If one or both of your torsion spring breaks, chances are that the cables on the door will snap because of the great amount of force that is often released by the break. Oftentimes, a snapped cable will damage a wall or car, and if someone is standing in the general vicinity of the cable when it snaps, a serious injury may result. Like with a broken torsion spring, you should never try and open your garage door when it has a broken cable.

Faulty Remote

If your remote control isn't working properly, your door may not work. The first thing you'll need to check is the batteries to determine if they're weak or dead. If the batteries are still fresh, try moving closer to the door because if you're too far out of range of your overhead door, it won't open.

After the batteries have been checked, make sure that the sensor on the remote is clean, because like the electronic sensor on your garage door, the sensor on your remote may be obstructed by dirt or debris. If these things fail to do the trick, you may have to reprogram the device, which you can do by following the manufacturer's instructions.

Tripped Circuit Breaker

If the circuit breaker that supplies power to the motor of your overhead door has been tripped as a result of a power surge or failure, the door won't go up or down. To determine if the circuit breaker has been tripped, locate the breaker box and if the switch that supplies power to the overhead door is positioned in the opposite direction of the other switches, it has been tripped. Simply push the switch back into its original position so that power is restored to the garage door.

If your garage door is malfunctioning, don't try troubleshooting it yourself. Call a garage door repair professional who will assess the situation and safely make the necessary repairs. If you need to get your car out of the garage but the electric door won't work, simply pull the emergency release handle to engage the door into the manual mode so that it can be safely lifted.
