3 MOST COMMON GARAGE DOOR PROBLEMS
Although there may be repairs and maintenance that you can’t handle on your own, there are common issues that you can fix yourself. The sooner you identify and fix the issue, the less damage and cost you’ll have later on.
Just a little reminder: These troubleshooting tips should be done at your own risk. If the issues are not self-evident, please contact us directly.
1) Broken Springs
Broken springs are probably the most common garage door problem. This is likely due to the garage door being inoperable after it or they break and in most cases requiring professional service for repair. In other words it’s not something you can typically put off while continuing to use the garage door. If you are unable to lift you garage door manually with one hand you likely have a broken or incorrect spring(s). Garage door springs can be extremely dangerous weather they are torsion or extension type. Always refer to your garage door repair company for replacement and adjustment of your garage door springs. If you have extension springs make sure you have safety cables installed!
2) Broken or Slipped Cables
Broken or slipped cables would be a close second as they are the link between the counterbalance springs and the door to be lifted. Having one broken or slipped cable will likely leave your door in a crooked position, if you are able to get the door closed. If both cables are broken or off, the garage door opener should not be able to lift the door beyond a few inches if even at all. Garage door cables can also be extremely dangerous as they are generally under extreme tension. Loose/frayed cable and ends can be very sharp. Never attempt repair or adjustment of your garage door cables. Always refer to your garage door repair company for any garage door repair or adjustment.
3) Garage Door Will Not Close
Although this can be caused by multiple different root problems most often this is a result of either a misaligned safety sensor or a dirty/blocked safety sensor. With Liftmaster garage door openers this is easily recognized by the lights on the motor unit flashing 10 times once the door reaches the full open position when it will not close fully. If your Liftmaster garage door opener will not close and you observe the lights flashing 10 times take these steps to possibly resolve or diagnose this issue yourself:
- Check the sensors at the door (typically mounted on or just next to the vertical door track roughly 6” off the floor) you should have lights on both of them. One will be green and the other either green or amber.
- If neither have lights on, stop here and call a professional as there is likely a more involved problem.
- If you have one light on, this is promising! If one light is on check for proper alignment and debris in front of or on the sensor(s), typically it is obvious if one of the sensors is not pointing directly toward the other or there are leaves, grass, cobwebs etc. blocking the sensors.
- If the sensor is misaligned often times you can move it back into position by hand.
- Sometimes you need to loosen the wing nut that holds the sensor to the bracket then adjust and re tighten.
