Common Issues And Solutions With Linear Garage Door Openers

When it comes to troubleshooting your Linear garage door opener, it’s important to familiarize yourself with common issues and their solutions. This will help you identify and resolve any problems you may encounter, ensuring smooth operation of your garage door. In this post, we will discuss two common issues and their solutions with Linear garage door openers: “Garage door keeps going back up” and “Blocked or misaligned infrared safety beam.”

Garage Door Keeps Going Back Up

If your garage door closes partially and then immediately reverses back up, it can be frustrating and inconvenient. Fortunately, this issue can be easily addressed by adjusting the travel down setting of your Linear garage door opener. The travel down setting controls the distance the door needs to travel before it fully closes. If the door closes before reaching this set distance, it may have detected an obstacle or safety threat, causing it to reverse. To fix this issue, follow these steps:

  1. Locate the travel down adjustment on your Linear garage door opener, usually found on the back or side of the motor unit.
  2. Using a screwdriver or the specified tool, turn the adjustment screw clockwise to increase the travel distance.
  3. Test the operation of your garage door by closing it. If it still reverses, repeat the adjustment until the desired travel distance is achieved.

By adjusting the travel down setting, you can ensure that your garage door closes completely without encountering any obstacles.

Blocked Or Misaligned Infrared Safety Beam

If an object obstructs the path of the garage door while it is closing, the infrared safety beam will detect the blockage and cause the door to reverse and fully open. This is a safety feature designed to prevent any damage or injuries. To troubleshoot this issue, follow these steps:

  1. Inspect the area around the garage door for any objects that may be blocking the infrared safety beam.
  2. Remove any obstructions, such as debris or stored items, that may be interrupting the path of the infrared beam.
  3. If there are no visible obstructions, check the alignment of the infrared safety beam sensors. Ensure that they are facing each other directly and aligned properly.
  4. Adjust the position of the sensors if necessary, ensuring that they are securely fastened in place.

By unblocking or realigning the infrared safety beam sensors, you can prevent unnecessary reversals of your garage door and ensure smooth operation.

In conclusion, addressing common issues with Linear garage door openers can be easily done by adjusting the travel down setting and checking for any obstructions or misalignments in the infrared safety beam. By following these troubleshooting steps, you can ensure the proper functioning of your garage door opener and avoid any inconveniences.
