The 5 Most Common Garage Door Malfunctions12/20/2016 Back To Blog
When the garage door doesn't work properly, you naturally want to find out what’s wrong. Is it the spring, the opener, or something else? Let’s take a closer look at the most common malfunctions, how they occur, and how they are fixed.
1. Jamming During Movement
When the door opens or closes and stops all of a sudden, the issue is most probably with one of the tracks. It could be blocked, bent or broken. The solution is cleaning, straightening, or replacement, respectively. Alternatively, one of the lift cables could be broken and has to be replaced right away.
2. The Door Doesn’t Open Although the Opener Runs
There are two possible causes to this issue. You may be dealing with a broken spring. Just look up to see if this is the case. Remember that you must never operate the door when a spring is broken. This is extremely dangerous and can cause damage to other hardware parts. Just disconnect the opener from the door and stay put until the spring’s been replaced. The other possible cause of this problem is a broken trolley. This is the component which is driven back and forth along the opener’s rail to open and close the door automatically. It must be replaced for the electric door to work properly once again.
3. Garage Door off Track
This issue typically occurs when a lift cable snaps. The door gets out of balance and starts hanging on one side. You must not touch it, in order to avoid injury and further damage. The solution to the problem involves replacing the cable and adjusting the door. If the track is bent, it has to be repaired and if it's broken, it must be replaced.
4. Noisy or Completely Silent Motor
In either case, the opener won’t work to lift the door. When the motor unit makes grinding sounds, the main gear is probably broken and should be changed. If it is silent, it may not be getting power or it may have failed. The solution could be replacement of the wiring or the motor, respectively.
5. The Door Reverses Instead of Closing
Usually, this problem occurs when the safety sensors malfunction. Try to troubleshoot them by cleaning them and aligning them so that they face each other. If this doesn’t help, they are most likely faulty and should be changed. A broken cable can also be responsible for this kind of issue; hence its timely replacement is essential. Another possible cause is a misaligned, bent or broken track. It should be fixed or changed right away by a professional.
