“Why Won’t My Garage Door Close!?” – Safety Sensor 101

Written by Nick McGregor. Posted in Garage Door Opener Safety Sensor Beam Photo Eyes ISBs

You’re leaving the house, kids are packed in the car, you’re off to a soccer game and running 15 minutes late.  You pull out of the garage ready to take off, glancing sub-consciously at the door, waiting for it to shut…and it doesn’t.  UGH! Why me, why now? The Simple Answer: your sensors are doing their job.  If the lights on the motor unit on the ceiling are blinking or flashing, something has likely broken the safety beam sensor (or ISB) path, or caused it to become misaligned; which will not allow your door to close.

Infrared Safety Sensors for Garage Door Opener

To minimize this occurrence in your life, and to keep you from yelling at your garage door (it has feelings too!), here are suggestions on keeping your door sensors happy.

First and foremost, the purpose of the sensors is for safety. Again, if anything breaks the path of the laser beam, the sensors will not allow the door to close. Period. Even if you don’t think so at the time, this is a good thing.  Too many accidents have, and still do, occur from doors closing on people, vehicles, lawn mowers, etc.

Secondly, when it comes to the sensitivity of the sensors, it can be extremely high.  This also is a good thing.  (See the previous sentence)  In order to keep them functioning properly, it is necessary to maintain them.  It takes all of 5 minutes or less; and here’s how:

  • Make sure to keep the area around the sensors free of debris. Sweep away any leaves, grass, etc that may interfere with the tracks/sensors.
  • Wipe the sensors gently with a soft, damp cloth paying attention of keeping them in place. If they’re moved too much, it will enable them from working, which will keep the door from closing, which will not make you happy.
  • Lawnmowers, kids toys, bikes, and rolling trash cans create 99% of these issues!
  • After cleaning the sensors, operate the opener to test the door and ensure it is opening and closing properly. This is also a good time to maintain your door and opener too.
  • Remember that the light on BOTH sensors must be lit up solid (they can be green, amber, or red).  The sending sensor is usually amber or red, and the receiving sensor is usually green or yellow.  Any flickering indicates alignment is needed.

PRO TIP:  Watch the sensors as the garage door operates.  Vibrations in the track, or even objects attached to the garage door (leaves, brackets, the bottom weather seal) can break the beam as the door closes.  Remember that garage doors age, foundations shift, and parts come loose over time!

Just so you’ll know, something as small as a fleck of dirt or a spider web may cause a break in the beam and allow the sensors to “work”.

One last thing…it is THE FEDERAL LAW to have sensors on all doors with openers. If you have an outdated opener it’s recommended that you consider replacing as soon as possible.

We hope this information helps you; if you have any questions, or would like to schedule an appointment to have one of our technicians come out to service or install a new garage door opener, please contact our showroom for an appointment today!

North Dallas Resident Couldn’t Close Her Garage Door

Customer Calls from North Dallas with a Reversing Garage Door Opener

ISBs Safety Sensors

A customer in Dallas called us because their garage door would not close unless they held down the wall console button. So we sent out a technician to the customer’s house. When the technician arrived he checked her opener and he then realized it was her ISB sensors located at the bottom of her garage door opening. Sometimes if there is even the littlest blade of grass in the way of those sensors it will cause the door to not shut.  The technician made sure the sensors were free of debris and made sure the customer also knew that they need to be in line as well. He showed her how to loosen the wing nuts and adjust them until both lights are light up solid as well.

After the technician was through the customer had no problem shutting their garage door. She was thrilled that she didn’t have to hit the button 20 times every time she tried to leave the house!

Preventative Winter Garage Door Maintenance

Written by Nick McGregor. Posted in About Our Different Garage Door Services in Plano, TX, Garage Door Maintenance in Plano, TX

Winter Frozen Thermometer

As we enter the winter months, we’re starting to see our usual winter season problems.  Garage door openers, hinges, rollers, and more are seizing up.  The colder it gets, the tougher it is for the moving parts of your garage door and opener to stay functional.  We see this particularly in screw-driven openers, and older model garage doors.  Keeping the garage door lubricated properly can prevent the moving parts from locking up at the most inopportune times.  It’s fairly similar to why our knees ache in the wintertime.  A professional garage door technician can lubricate and adjust every aspect of the garage door system in order to help prevent this problem from arising.  

Have your garage door and opener serviced by professionals at least once per year.  The International Door Association recommends that you have service done twice per year as the temperature changes.  Preventative maintenance can save you money in the long run.  Try to think of your garage door in the same way you might think of your automobile.  Would you go 5 or 10 years without an oil change?  Unfortunately most homeowners go for 4 or more years without having their garage door and opener serviced.  Consider the fact that scheduling maintenance ahead of time can keep those bolts secure, prevent rusting, and can point out problems that might continue to worsen over time so that you can keep an eye on them.

As part of the recommendation to have service done twice a year, the service you have done just before winter can be the most important.  Rigidity caused by lower temperatures makes everything act up, and nobody wants to be sitting in their garage when it’s cold outside trying to figure out why their garage door got stuck half way open.  Do yourself a favor and lubricate all the moving parts of your garage door with proper lubricants.  But be careful, applying the wrong lubricant, or applying the wrong amount can do more harm than good.  Refer to the professionals if you’re not sure what to use, how to use it, or where to apply it.
