My Garage Door Won't Go Down!

One of the most common problems we will have with our garage doors are photo-eye sensor related.  You may be asking what in the world are the photo-eye sensors?  In the lamest terms they are the two "eyes" located on the bottom of your garage door and are about 6 inches off the ground.  How these work is one devices shoots an invisible beam that directly points into the optical receiver of the one on the opposite side of that opening.  These two gadgets prevent your child, pet or even a careless driver from being crushed by the operating garage door should it become active while any of those things create an obstruction.  Basically, when there is an obstruction that cuts the direct contact between the two sensors, it breaks the circuit which then tells the operator that the door cannot be closed or that it must roll back up to prevent damage to your vehicle or injury to your pets or family members.  Which is why they are now a government regulation and most operators will not work if they are disabled.  Some of the most commonly reported problems of this safety feature are:

• Sporadic stopping and starting
• Flashing lights
• Door only goes down about a foot and bounces back up
• You have to hold your wall panel button down until the door completely closes

There are a few things you can do to solve your sensor issues and avoid an expensive simple 5 minute service call.

First, you want to locate your two photo-eye sensor devices, then try to see if each one has a lit LED light.  Sometimes you will notice that one is lit and the other one is either off or flickering.  What does this mean?  It means a couple of things.  For one you might try adjusting the sensor height by moving it with your hand because it may be out of direct alignment, they may have been bumped while taking the trash out or even the vibration of the door over time has knocked them out of alignment.  When moving that sensor around and the light goes from off or flickering to bold secure the device in that location and try running the door and it should work!  The other problem that often occurs with sensors is that they get dirty.  Let's face it when was the last time you vacuumed your garage and made your sensor lenses squeaky clean?

If aligning the sensors didn't help, check to make sure the lenses on both sensors are free of any debris, cobwebs or dirt.  If you notice anything go ahead and wipe them clean with a damp cloth and dry the residue with a dry cloth, being sure to not bump them out of alignment.  If you are still having problems, check the wires and make sure none are pinched, ripped or clipped.  Fixing a wire will take a little handy work that most people can perform.

The only bad news is that if all the above have failed, there is problems with your wiring somewhere or your photo-eye sensors are broken.  In some cases people have their garage floors pressure washed and someone forgot to cover the sensors so they are burnt out from moisture.  Sometimes, especially those homes located in rural areas, they can have rodent residents that chew on wires and in some cases the wires have been drywalled over which make the situation a tad more complicated.  An easy fix would be to have the sensor wires run exposed (stapled on top of your drywall).  Another common problem are the garage doors that seem to malfunction at certain times of the day during certain seasons of the year.  That problem is due to the sun directing light into on of your garage sensors at a particular time frame of day.  That problem can be solved by adding sun shields to your sensors and more often than not the malfunctioning garage door sensor problem is solved.

How to Winterize your Garage Door!

Tis' the Season! For broken springs, worn operator gears or worse it's 7:30am you need to be at work by 8:00am and your garage door won't go up! As much as we would love to help everyone right away our office is swamped with service calls and when the weather really drops we will be lucky to get to you the next day! 

Here are some thing you can do to help lengthen the life of your door as well as prevent costly repairs:

The first line of defense is to lubricate the moving parts. As shown in the diagram to the right, apply a silicon based spray lube to all rollers and hinges. There are end hinges which hold the rollers in the track, as well as center hinges which pivot as the door moves.  Lubricate all pivot points. DO NOT lubricate the track itself.

While lubricating, you should also check the garage door hardware parts.  With repeated use, the hardware on the garage door will tend to loosen over time. If you notice any loose screws, bolts or nuts, tighten them so hardware parts won't fall out of adjustment.

Garage door springs should be coated about once every season.  Allow the oil to drip down and coat the cables on the side of the garage door.

There are two types of spring systems see below diagram to determine which system your door has.

Extension Spring

Torsion Spring

NOTE: springs are under very high tension due to the loads they must lift

and can be very dangerous.  Do not attempt to adjust spring tension yourself.

The extension spring system will run along the tracks of the door, torsion spring system will run above the actual door itself.  When lubricating the springs be sure to get a good amount on there but not so much that it drips off the spring, you don't want the oil to drip on your door when its open.

You also want to lubricate the Operator Rail, which is the bar that connects to your Operator hanging from the ceiling, again being careful with the amount so its lubricated well but not dripping.

We use SLIPIT Mechanic's Spray Lubricant with Silicone you can find it online or at your local hardware store.
