No matter how much you take care of your garage door, it’s impossible not to spend the years without any glitches. It is essential to be familiar with simple troubleshooting strategies to help you in fixing your garage door without spending a ton of money. Oftentimes, these common garage door issues can be fixed on your own with simple tools and you can save extra cash by doing so.

If your garage door won’t close, it can spell out security issues for you. So, fix your garage door right away with these simple steps:

1) Check the sensors.

Safety sensors are made to ensure that there are no objects blocking the garage door. This prevents objects or pets from being run down by the largest moving part in your home. Check if the sensors have a solid red or green light. If it does, it means that the sensors are aligned correctly and will work as it should. If it is blinking, then it’s not properly aligned and will not work properly. Just readjust the sensor and ensure that the pair is facing each other. In addition to that, check if there’s an object blocking the sensor. Sometimes, little objects might go unnoticed yet block the sensors and keep the door from closing

2) Sunlight against the photo sensor.

See if the sunlight hits the photo sensor on your garage door opener at certain times of the day. When it does, it might affect your sensor and will not close your garage door. Try covering the sensor with your hand and close your garage door. If this works, then remedy this by putting a visor or a cover over the sensor to block the sunlight.

3) Clean the sensors.

While you’re at it, take the time to clean the sensors. Dust and other particles may settle on the sensors. So clean this up to make your sensors like brand new.

4) Check the wiring.

Sometimes, connecting wires are just little things in the entire system that are ignored. However, these can affect the operation of the opener system. Check the wiring in your garage door opener system. If there is corrosion on the wiring or are not connected properly to the sensors, the safety sensors might not line up correctly. Sometimes, staples may have gone through the wire during installation. As time passes, wires on the staple may have severed due to vibrations. You might need to change the wiring or re-staple the wire to secure it.

5) Inspect the tracks.

If the previous steps did not help you, then you should inspect the tracks. If tracks are too tight against the rollers, this might not close the garage door properly. What you need to do is to look for signs of friction on the track. You might see screws and tracks that have been scraped off by roller friction. This happens when there is not enough room on the tracks and the rollers are too tight against the track. When the garage door goes down, it pinches the track and gets too much resistance. Because of this, the garage door goes up. The rollers should be loose and able to move around the track. If the rollers are rubbing against the track, loosen the bracket with a wrench and hold the track out so it’s not pinching against the roller. Then, tighten it again to secure the track.

6) Adjust the travel setting on the garage door opener.

When the door closes, the weather stripping on the bottom of the door has to be in contact with the ground. If the garage door doesn’t go down that far, then you have to adjust the opener until it does. To do so, remove the case of the opener and look for the adjustment knobs. One knob controls how far the door closes while the other controls how far it opens. Adjust the knob accordingly to lower the door down but not too far that it already pushes against the top track.

7) Change the gear.

If your door does not close and you hear a grinding sound, the gear inside the opener is worn out. You may need to replace the gear on your own by consulting the manual. This may be a difficult DIY solution for you. Remember to release the emergency cord and disconnect the power before you start changing the gear. If you think you cannot do this on your own, always consult a professional.

  1. I knew there were sensors for garage doors, but never realized they have to be lined up together so there is a solid light. Our garage door has been giving us some problems and won’t close. I’ll see if the lights are solid on the sensors, and hopefully it’s that easy of a fix!
