New Garage Door Motor Installed – Sandton

Do you need a new garage door motor installed in Sandton? Please contact Mr Garage to install a new garage door motor for you in Sandton. We specialize in garage door automation, garage door repairs and garage door installations.

Our client in Melrose road in Sandton recently called us and reported the following:
  1. My garage door motor is broken
  2. It was making a funny sound before it broke
  3. My garage door motor does not want to work at the moment
She had a Pro-Alpha garage door motor. There is basically no support for these motors at the moment. They are old 220V motors and we strongly recommend that you install a new Centurion garage door motor. We did the following tests
  • We first checked if there is power at the motor (220V in this case). In some cases the plug or db board tripped and, because of this, the motor stopped working.
  • Then we check if there is 12V or 24V present at the receiver. Sometimes a fuse has broken and the receiver cannot trigger the motor.
  • So, can you trigger the motor manually? In this case we could not trigger the motor.
  • Finally, we check the carriage and drive or chain mechanism. The carriage was stripped so it would not be able to lift the door any more.
We installed a new Centurion X-trac motor and had a happy client in no time.

Another garage door motor installed in Sandton…

In another case, we did a lot of work for a client in the Sandton Country Club Estate. The garage door broke and, in the process, the pine jams got damaged and needed to be replaced. A couple of months before this happened, one of his garage door springs broke and another company installed new springs for him. The problem, however, was that this other company did not weigh the door and installed incorrect springs. The door never worked properly. This damages the motor. We weighed the door and installed the correct springs. After the door was working properly we installed a new Centurion SD04 garage door motor.

And a third garage door motor installed in Sandton…

In yet another case, a client in Coleraine Dr in Riverclub, Sandton, had a broken garage door motor. The type of motor was an old imported 220V motor with no local support. Mr Garage only installs well-supported local brands of garage door motors. Our preference is the Centurion X-trac and SD04 motors. We replaced the motor and, once more, have a happy client.

Centurion RDO II Garage Door Motor for Roll-up Doors

The Centurion RDO II garage door opener is a great motor to install for your roll-up garage door. As usual, there are a couple of options for automating roll-up doors. The one that we recommend is the Centurion RDO II. We install the motor on either the left or the right hand side of the door. This will depend on available space and cabling. The shaft of the garage door goes through the RDO motor and the motor fits through one of the wheels of the garage door.

Roll-up garage door

A roll-up door consists of a single piece of steel. The doors rolls up into a cylinder. It is important that your door is in a good mechanical condition before considering automating it. If your door is older than 10 years you should consider installing a new door before  automating it with an RDO. A roll-up garage door is sometimes also known as a roll-a-door or roller door.

Basic Features of the Centurion RDO II Garage Door Motor

The Centurion RDO is a 24V DC motor. So during power outages you have battery backup. The motor is strong and can easily lift any single roll-up door. Please note that old doors need to be serviced before installing this motor. A door that is not working optimally will damage the motor. Whisper-quiet operation means this motor makes very little noise during operation. It has anti-crushing technology to detect if something is obstructing the door during operation. Plus, you can also fit Infrared Safety Beams and use the auto-close feature to automatically close the door after 30 seconds of passing the beams. Furthermore, it has a wall mounter controller with a courtesy light. We can programme the on-board code-hopping receiver to:
  • Open/close garage door.
  • Switch Courtesy Light on and off.
  • Override automatic closing.
  • Electronically lock the system for added security.

Installing the RDO

Correct installation of the Centurion RDO II motor, together with a mechanically sound garage door, will give you many years of great service from the motor. However, there are a couple of things we regularly see that should not be done by the installer.
  1. The installer should not install the RDO on a wheel that is not compatible by using a hack saw to modify the wheel so that the motor fits. This creates a weakness in the wheel, and very often the wheel breaks and can cause both the motor and the door to break.
  2. If needed, we can install a wheel adapter or a compatible wheel. The fork of the motor should fit over one of the webs of the garage door wheel.
  3. The door needs to be serviced so that it is in a good working condition before the motor gets installed. Many garage door motor installers can only install the motor, but do not have a lot of knowledge regarding garage door mechanics and working. We often find that a motor is installed incorrectly and that the door is not working properly.

Using your RDO

Using your Centurion RDO II is very simple. You simply press the button for the required function on the remote and it should work by either opening your door or switching on a light etc. There are however times when either the motor or the garage door experiences a problem and you need to understand how to get the motor in manual mode or disengaged. To do this, you will notice a red cord on the side of the motor. You need to pull gently down on the cord until it clicks. If you look at the motor, there is a lever that is pulled down to engage and disengage the motor. This is lever is spring loaded. Always make sure that the cord is hanging on the side of the door and motor so that is does not get broken when you open and close the door.

Fault finding and problem solving

When you experience a power failure or load shedding, your motor has battery backup and should be able to open the door about 10 to 15 times. Please note if you have external receivers or beams connected to the motor that it will consume battery power and after a couple of hours you may find that your door does not open. So, if you know the power outage is going to be a couple of hours, then put your door on manual so that you can easily open your automated garage door. Please contact us if the following happens:
  1. My door opens but does not want to close
  2. My door closes but does not want to open
  3. Nothing happens when I press the button
  4. Someone drove into the door and it does not want to work now

Garage Door Motor Repair Linden, Randburg – 9th Street

We recently had a client for a garage door motor repair Linden, Randburg – 9th Street. Previously we had done a lot of work on their garage door hardware and also on their garage door motor. We replaced their garage door opener batteries a couple of months ago. However, recently there was a power outage, and, after a couple of hours, the motor stopped working. The first step in understanding the problem is to understand where the problem is occurring. When we arrived at the client we unplugged the garage door motor. Next we started testing the motor using only the battery backup. The motor opened the door many times without a problem. So it is clear that the motor and battery back-up were fine. But that something was discharging the batteries during the power outage.

There is an external receiver connected to the motor. This is the piece of equipment that communicates with the remotes and then causes the motor to either open or close the garage door. A garage door motor also has a PC board. What you have to keep in mind is that both the external receiver and the pc-board of the motor consume a little bit of current continuously. This means that, even if you are not opening and closing the garage door and the motor is not operating, the pc-board and the receiver will continue to draw current from the battery. The batteries used for this particular motor are 2 x 12V 1.3 A/h. Please note that if a lead acid battery is rated as 1.3 A/h that you will probably only get about 75% of that rated value over an hour. (In other words, only 0.975 amps per hour). So, if the pc board and external receiver together consume about 300 mA continuously, the batteries will last between 3 and 4 hours. This is exactly the amount of time that passed before the client tried to operate the motor and found that it would not open the garage door.

Garage Door Motor Repair Linden Solution

The solution for this type of problem will depend on a couple of factors. How much time does the client expect the motor be able to last during a power outage? What budget does the client have? 1) It is possible to install 2 x 12V 7.2 A/h batteries. This should give you roughly 5 to 6 times the time as the 1.3 A/h batteries. 2) A different external receiver can be installed that consumes less power 3) Solar power solutions or generators / inverters are other options (these are usually quite pricey though)

Centurion Garage Door Motor X-Trac

The X-trac, a Centurion garage door motor, is Mr Garage Mr Garage’s favorite garage motor to install for automating a garage door. Suitable for both sectional and tip up garage door, but not a roll up garage door. And used for both steel and wooden doors alike. With 24V battery backup to make sure that your door opens during power outages or load shedding and super quiet operation you can rely on the X-trac garage door opener to give you great service and performance for many years.

Garage door motors and automation
The motor design is split in 2 sections (See image below). Firstly there is the 24V motor part moving up and down the shaft which is in turn connected to the door. It has a steel cord with a red knob that is pulled gently to engage and disengage the motor. This can be done at any point of the shaft.
