One of the most common problems with garage doors is when they randomly open or reverse while closing. Many homeowners ask the pivotal question, “Why would my garage door randomly open?” There are a few possible answers. If a garage door opens on its own, and doesn’t obey your commands, here are some reasons why:
Photo-eye sensors are quite reliable but also responsive to any type of debris or blockage. If your garage door randomly opens midway, check whether the sensor itself is dirty or smudged. Also check whether leaves, dirt, snow, or ice have built up around the door or near the floor sensors.
Solution: If the issue is caused only by something blocking the sensor, the solution is as simple as clearing debris, wiping it off, and ensuring it’s clean so there’s a clear signal.
When you’ve cleaned the sensors and still notice the garage door opening at random, check whether the safety sensors are aligned properly. These sensors work by directing a beam of light across the door opening; when the beam is blocked, the reverse mechanism is triggered. A misalignment happens when one sensor is not pointed directly at another. The receiving sensor will display a green LED if it is working; when this indicator goes off, flickers, or starts to dim, something needs to be fixed.
Solution: Push the sensors back into alignment if possible. But a technician may have to fix the sensor position or repair a bent or otherwise damaged track that has affected the sensor.
Transmitter or Remote Issue
Sometimes, you might find that the garage door opener remote doesn’t trigger a response. Transmitter issues can occur as well. Sometimes these are due to radio frequency interference. Radio waves are used to open a garage door, but a faulty transmitter can block these from triggering your door to close, or this can trigger your garage door opener at random.
Solution: Change the batteries in the remote; if that doesn’t fix the issue, try the wall panel to see whether there’s a problem with the garage door remote. However, if the problem still isn’t fixed, there may be a problem with the transmitter, in which case you’ll need a professional to inspect the system.
Damaged Electrical Circuits or Wiring
Power outages, electrical surges, and severe weather can damage electrical circuits and garage door opener parts. Your garage door can then operate erratically. Damage to the wiring that runs from the motor unit to the wall-mounted opener, and the sensors, can short circuit or lose insulation. Wires may also be damaged by rodents, shovels, or a nail or staple.
Solution: Electrical issues can be difficult to fix, and dangerous. Once you find a potential issue after inspecting the system, hire a garage door electrical professional to fix the problem.
Your garage door might not close properly because a spring has worn out and broken. Garage doors rely on heavy-duty springs to support their weight and won’t close properly without them. Replacing a spring on your own is dangerous, as garage doors are heavy and an unstable spring can easily injure you.
Solution: Inspect the springs to identify any problems. Contact a professional if you see a gap in the spring or it is rusted or severely worn. Do not touch it. Have a technician replace the spring right away.
If garage door opener troubleshooting hasn’t revealed any potential causes, there may be crossed signals. This can occur when a neighbor is using the same frequency or code that’s used to open your garage door. In some cases, a nearby radio, appliance, or other wireless devices may interfere with the system, making you think you have a broken garage door remote or other problem.
Solution: Check if there any wireless devices are interfering with your garage door opener. If so, you can try resetting the code. Also, see whether your close neighbors have the same type of garage door and ask them to open it. If yours opens at the same time, reprogram the remote.
