THE GARAGE DOOR INDUSTRY-EXPLAINED

by Roy Bardowell, CDDC

Since my stroke in 2014, I have met dozens of medical professionals over the last 6 years. During conversation, I am often asked “What Do I Do?” When I tell them, I am an engineer in garage door automation; they seem confused. Most are aware of garage doors, but many are oblivious there is an industry involved in many aspects of garage doors.

In this article I intend on tackling the many aspects of garage doors and the automation of these doors. First & foremost; there is the garage door itself, which comes in many forms:

The most common garage door type sold is the residential garage door (pictured above) only because there are millions of homes in the USA and Canada combined. Some homes have more than one garage door, which also adds to the greater residential total. I estimate the North American and European sales of garage doors are nearly equal. Residential garage doors are mostly sectional type doors meaning the door is made of multiple sections linked by hinges and move up and down as one unit through steel tracks.

Most residential garage doors are made up of two sheets of steel with a foam core. The foam core can be styrene or Poly-Urethane type. The foam acts as a binding agent that holds the inside and outside steel panels bonded. A small portion of residential garage doors are one-piece doors, mostly found in California.

This foam bond is what turns two floppy steel sheets into a strong stable durable board. The foam is not only the binding agent that keeps a door section stable and solid, but also serves as insulation to keep your garage warm and toasty on cold winter nights. The process of bonding two steel sheets by a foam core is the basis for most steel insulated garage doors. The exception is steel roll-up doors likely found in Storage Depots. These simple rollup doors (aka continuous sheet door) have found a good home in Australia, New Zealand and sporadic locations in Europe.

Second most popular door is commercial garage doors which are also produced in many forms for the many types of commercial buildings.

Commercial steel garage doors also use the very popular foam core to bond the outside and inside steel panels which in turn produces a stronger board which is required in Commercial or Industrial garage door applications. Commercial Doors are also produced as roll-up type doors also. When you get into commercial roll-up type doors, the types outnumber many others in the field of commercial doors. If I take a step backwards to the continuous steel type; this type can be made with and without insulation and a is a less expensive version of the rolling steel curtain door.

Rolling steel curtain doors are typically made from multiple steel slats that are interlocked together. The interlocking permits the multiple slats to be rolled around a barrel or pipe which is common in most rolling doors.

By interlocking more slats, a door can be made into nearly any height. By utilizing heavier steel slats, a manufacturer can produce a fire rated door. With rolling steel fire doors, the way they are automated is very important. If a fire occurs, a fire or smoke detector must signal the operator to close the rolling steel door. Once the rolling steel door is closed, it is presumed the fire will not spread into another area of a building resulting in lives and property saved.

To ensure a fire door is reliable the fire door must be drop tested every year.

Commercial door operators can connect to the barrel with gears and chain.

By rotating the barrel, a slat door or grill type door can be lifted upward or dropped down. Another popular rolling product is the security grill; aka rolling gate.

This product can be used for security or when ventilation is desired. The most common place where rolling gates are found is in malls in front of store fronts, but also is heavily used in parking structures.

In this article, I will refrain from going too deep into the many ways to automate a door, because the full explanation would be too long. For that, I will follow up with another document in the Summer of 2020. Look for other documents explaining our Industry in the coming months

In closing, let me remind everyone; JUNE is garage door SAFETY MONTH!

June is the time for manufacturers who produce motorized door openers to remind homeowners your garage door could be unsafe and must be periodically maintained TO OPERATE WITH THE UTMOST SAFETY.

    I have a Clicker KLIK2U.... Does it work with a Guardian? If so what is the id code for Guardian

    A Clicker is not Universal.  It will not  work with a Guardian garage door opener.  Google "Guaridan GDOR2B" for sources that will sell a compaible remote.  If more help is needed please call 1-424-272-6998.

    We have a 2011 Ford Escape with an Interior System for operation of Exterior Gates, Garage Door and House Security Lights. I am unable to Program the Guardian 630SL with the vehicle equipped system which worked with the other Garage Door Opener our home had. Is there a reason I am unable to set up this Opener purchased from your company using the "Guardian Remote Clicker" the only answer to this inconvenience ?

    Elmore,

    There are two systems auto manufactures supply with their cars, HomeLink, made by Gentex and Car2U made by Leer Corp.  Guardian operators are compatible with HomeLink, but not Car2U.  Please check your car's owner's manual to see what system is used in your vehicle.  There should also be a phone number in the manual to call for help in programming either of the two systems.

    I have two guardian remote controls that do NOT open our Guardian garage door opener. I have replaced the batteries in both units, and they still do not work. However, the external wall mounted wireless garage door opener works, as well as the embedded garage door openers in our Honda cars. So what is not working are the two guardian remotes. Please provide some direction to troublehoot and solve this issue.

    Thanks in advance...Scott

    Hi Scott,

    Have the remote controls always worked with the garage door opener or is the issue something recent?  The fact that the HomeLink system in your car is working indicates that the radio receiver in the opener is working.  What are the model numbers of your opener and remote controls?  To talk directly to a tech who can help to troubleshoot, call 1-424-272-6998.

    Is there a way to put the lights on the opener in "motion" mode, rather than just coming on by pushing the light button or opening the garage door?

  1. Brian's picture
    Dec 04, 2017

    Dear Alayne,

    Some gargae door openers have a special control console that can provide this function.  Your Guardian opener is not adaptable to this console,  A less expensive alternative would be to replace the light switch in your carage with a passive infrared motion sensor wall switch.  This switch will recognize a presence in the room/garage and turn on/off lights accordingly.  A garage door opener system works with a set timer, so lights can remain on even after the person has left the garage.  The switch could be purchased at any hardware of store or home center.

    I recently posted complaining about the motor. I found a number for Guardian technical services online and as a last effort I called them. Technical services was great and helped me fix the problem fairly easily with directions over the phone. I’m impressed with corporate but still disappointed in the local installer as since the day they installed the opener they come across as more interested in generating charges than doing what’s right for the customer.

    Thanks to Technical Services!

    I'm in New Zealand. If I can't source this for my Guardian 21230DL, I'll have to discard an entire garage door opener which works perfectly well just because it can't receive the signal from the remote.

    I looked for an internet sale on your website but couldn't find it.

    Considering that it will cost $800 to replace the whole door opener unnecessarily, I would really appreciate your help.

    Roy, I have six two button remotes, the black rubber inserts fall out and I have to use a small object to activate the opener. Would it be possible to send me five or six replacements. I would happily pay for them.

    Hello,

    My garage door motor is beeping every 15 minutes. Is this due to my remote battery being low or the motor being low? I'm having trouble locating a batter on the actual motor.

    I read the comment on how a clicker is not universal and will not work on guardian garage doors. Specifically could you please suggest one that will work? Your tech phone number is useless! I've left two messages and not received a return call yet and its been three days. No one ever answers either.

    Any Guardian remote control listed on the remote controls page on this website will work with any Guardian operator.

    If there are issues reaching technical service please feel free to contact a regional office (also listed on the website).

    My garage door will not work with the wall panel unit. The remote control units work and the keypad outside works. Any suggestions?

  1. Brian's picture
    May 14, 2018

    Hi Sherri,

    Is the LED back light on the panel glowing?  Check the wiring first.  The plug on the end of the wire leading from the control banel should be securely plugged into the "wall box" recepticle on the motor head.  Check for any wire shorts due to staples holding the wire to the wall.  Check the wire terminal connections on the back of the panel.. If more help is needed please call 1-424-272-6998.

    Lost power and opened the garage manually, power came back on the door opened almost completely and stopped. Beeping 20 times checked no lights on. Metered the wires for power, 21.08 tried aligning can't get any LEDs on?

    Dear Jada,

    20 beeps signified a photo-eye misalignment or faliure.  Please call Guardian Tech Service at 1-424-272-6998 to resolve.  Thanks

    No lights on the photo eyes. I think the logic board is out. Can you help me?

  1. Brian's picture
    Jan 07, 2019

    Hi Clinton,

    If the operator still opens the door and a constant pressure on the push button (PE override) closes the door, then the circuit board is probably not the problem.

    1. Check at the operator head to see if wires are in the 4 photo-eye terminals.  Sometimes installers will twist wires togther and use only 2 of the terminals.  This reduces power to the photo-eyes.  It may work initially, but over time as the wire develops more resisitivity, power declines.

    2. Check the alignment of the eyes.

    3. If LEDs fail to appear, after careful alignement, then replace the phot-eyes.

    4. Call 424-272-6998 for further help.

    I have no lights on my photo eyes. I have two garage door openers and tried the logic board in the other opener and the lights would come on. This tells me the logic board is good. Wondering if it might be the transformer.

    Jan 23, 2019

    Clinton,

    If you plug the photo-eyes that do not light-up when plugged into operator A into operator B and they light-up, the eyes are good.  Replace the logic boaed in operator A.

    Call 424-272-6998 for additonal assistance.

    Hi Roy,

    Thank you for the blog. We have a Guardian Pro Series 628 which was installed about two years ago. We have constant problems with the sensors and believe this is cause by glare from the sun since we experience the problems mostly during the day. Are there specific safety sensor sun shields (that's a mouthful) that work with these units? Also, the green light on that side blinks slowly all the time but the door still goes up/down. Is that normal? I thought both lights should be solid.

    Thanks!

  1. Brian's picture

    Hi Jim,

    There are no stock sun shields for photo-eyes.  Fabricate a shiled from cardboard or an empty paper tube and tape to the red (receiver) photo-eye.  Another trick would be to reverse the position of the eyes, placing the receiver eye on the shaded side (if there is one eye in bright sun and the other in the shade). 

    You are right, both red and green LEDs should be steady.  The flashing green could be due to misalignment or a poor connection at the operator head.  First, check the PE alignment.  If necessary, remove the wing nut holding the sensor for full range of motion.  Next, check the terminal block on the back of the motor head.  The first 4 terminals (L to R) are for photo-eye wires.  Each terminal should have one wire inserted.  At times, installers twist together pairs of wires.  Not using all terminals cuts the ammoun of current avaialble to the sensor and could cause the LEDs to flash.  If these two steps do not work, call 424-272-6998.

    We had a long power outage and when power was restored opener would not open. I pulled the red cord to open manually and now the opener doesn't work at all. It doesn't even seem to be connected. Do I just need to reprogram the opener? Thanks!

    I bought a Guardian Garage Door opener and from day 1 it has been temperamental when using the remote to open and close. If i am too close or push the button to long or too short a time. I had the installer return and ask questions, it appears Guardian knows their problem is the RF signal being sent at too rapid a rate or something of the like.
    DOES GUARDIAN HAVE A SOLUTION TO CORRECT YOUR ISSUE? At present i would never recommend this product or ever buy another, my second door will not be replaced with a Guardian.

    My green side is frequently blinking, so the door can't open/close. Lens are clean, no obstructions and we've tried adjusting the green side left/right, up/down with no luck. Sensor wiring appears secure. What am I missing??

  1. Brian's picture
    Jun 21, 2020

    Hi Thomas,

    First check to see whether the eyes have been properly wired into the operator head.  There are 4 terminals for photo-eyes.  All 4 must be used in order to provide full power to the eyes.  Lack of power can cause the blinking condition.

    A short in the photo-eye wires can also cause the green LED to blink.  Over time, expansion and contraction due to weather, can cause a staple to break the wire insulation. 

    See this link for more advice: https://www.adhguardianusa.com/technical-references-troubleshooting-photo-eyes
