Your chain drive garage door opener is tasked with operating the largest moving part in your entire home. With this type of responsibility you want to make sure that the opener will work consistently without any problems. When problems do occur you should know how to fix them easily and quickly. In all garage door openers, there are two areas where problems can occur. They are located in the motor unit and the lifting mechanism itself. Troubleshooting your chain drive garage door opener is easily done by following a few steps.
Always Look for Loose Hardware
Before you start checking out any other problems that might be associated with your chain drive garage door opener, begin looking at the various nuts and bolts on the unit. These can be in the rail system, the mounting brackets, and lifting mechanism. When these work their way loose, and they sometimes do, it can cause your opener to do some crazy things. Binding, moving, raising intermittently, bouncing, and hitting the floor hard are all problems associated with loose hardware. Take some time to tighten these up to ensure that things are working smoothly.
Uneven Rails and Tracks
Some problems are associated with the actual installation of the garage door opener. If the rail system is not perfectly level, the chain can eventually bind up in the process of working the door. Also, the garage door slides along two door rails on either side of the garage. Place a level on these and the rail to check to see if they are level. If they are not, adjust the height to the point where they will work without any problems.
If the chain of the chain drive system is not cleaned on a regular schedule you will find that it will not work as smoothly as it should. While there is a certain level of bouncing involved with a chain drive opener, it should not be overly bouncy and cause the chain to slip. Look at the chain and clean any type of gunk, grime, and dirt that will accumulate there.
Door Reverses on Contact
There are times when the door will reverse its direction as it makes contact with the garage floor. This can be caused by two different things. One of the problems can be with the travel length of the garage door opener itself. Adjust the amount of travel in the system to keep the door to a specific stopping point. Another problem that might cause this is a malfunction of the electronic eye. If there is any type of obstruction that is getting in the way as the door closes, it will immediately reverse its direction. Clean the lenses and make sure there is nothing interfering this the eye. Even a shadow that is made by closing it will cause this to happen.
Door Does Not Raise
Sometimes the manual release for the door is pulled, causing the opener to disengage from the lifting mechanism. The garage door will operate, but the door is not going to raise or lower. Check to see if this has happened and set it back into position.
