Technical Advice for Automatic Gate Opener Problems


COMMON AUTOMATIC GATE OPENER ISSUE AND SOLUTIONS

Can you find what gate opener issue you will have with this board in your All-O-Matic operator?

If your gate opener issue is on this board, you should probably call a local San Diego automatic gate company.

Your gate opener issue is usually a simple fix.  The last place you should look is on the board itself though.  Here are five of the most common issues we find:
Gate Opener Issue 1:  The gate opener issue is it won’t make a sound, try to move or anything at all.

Most Common Solution:  Check the breaker and any switch.  Also check your outlets for a tripped Ground Fault Interrupt (GFI).  When these trip they will stop all power to any outlet in the circuit so make sure you look at all GFI outlets.

Gate Opener Issue 2: Gate won’t stop in the right spot. Most common solution:  Limit switch nut or cam is not hitting the limit switch at the right time.  Adjust the limit nut or cam to the correct place on the limit shaft.  On slide gates, the nut is held in place by a lever riding inside the slots of the limit nut.  This must be pressed back out of the slot to adjust. The stopping points may vary by an inch or so but should not change substantially.

Gate Opener Issue 3:  The gate will only open when I am close to it. Most common solution:  The antenna has been cut or shorted to ground.  Most gate openers have separate receivers.  These usually have the name Multi Code, Liftmaster, Linear and Mega code on the m.  The remote “clicker” will also have this same name.  Press the remote and listen for a click from the machine.  The click is coming from the receiver.  Check the antenna and make sure it is as high as it can go without touching any metal.

Gate Opener Issue 4:  The gate won’t close: Most common issue:  The photo eye or other device is holding it open.  First turn off all power using the breaker.  This will cause any call box to release the gate.  Turn the motor back on, then look for  the loop detectors inside.  If the “detect” led is lit red, then you likely have a loop problem or something is sitting over the loop.  A photo eye will light up a safety LED on most opener control boards.  Check to see if it has a reflector.  If so, see if it is wet or misaligned.  Wave your hand in front of the photo eye.  If it clicks, it is usually good.

Gate Opener Issue 5: The gate keeps reversing direction: Most common issue – Obstructions:  If it is a slide (wheeled and rolling) gate the track may have something on it like a rock or plant material.  The wheels might be bad or have string or a shopping bag wrapped around them.  On a swing gate, lube all of the joints then check the level of the gate.

If any of this is confusing or does not work.  Give us a call.  Our rates are typical for the industry but out knowledge of gate automation and electronics is at the highest level.  We use diagnostic tools and methods, not guess work.  Do it yourself until you can’t, then call a professional.

Doorking 1812 – Changing Entry CodesDoorKing Telephone Entry System

The most common request we get is to change the current codes in the 1812. Here is a very simplified procedure. It assumes the code is located in position 01.

You must enter these codes quickly or it won’t work!

Start by entering the following: Press * 0 2 and enter the four-digit MASTER CODE(the last four digits of your serial number usually) you should hear a beep. (the “*” is on the keypad opposite the “#” sign)

Enter 01then press * (beep).
Enter the new four-digit entry code _ _ _ _ then press * (beep).
Press 0# TOGETHER to end this programming step (beeeeeep).
You may have to do this a couple of times to exit out of the programming.

This should change your main code. If you have multiple codes or have difficulty with this procedure, you may want to call us and start fresh.

Please e-mail us with your own tips and tricks for fixing your Doorking 1812.  It will help us to explain procedures better.

Programming Transmitters / Clickers / Remotes

There are several different types of transmitters with their own frequencies, codes and methods of sending those codes.

First, they all must match the type of receiver the gate operator uses. To determine this you need to find the antenna and follow it back to the receiver. In many, if not most cases, the antenna is attached to the receiver and will be located inside the operator cover.

Make sure you are clear of the gate operator parts and the gate. It may start to move.

Once you know the receiver brand and model number, you can program the transmitter.

There are three basic types. The first and the easiest to program is one with a learn button. In these, you will push a button on the receiver, then push a button on the transmitter. On some, you have to push the receiver button again. Usually, you will know it is programmed when the light on the receiver goes out or the gate receiver clicks.

Make sure you are clear of the gate operator parts and the gate. It may start to move.

The second type is a dip switch transmitter. This has a series of tiny switches inside the transmitter and receiver. These will need to be matched to each other. These are easily duplicated and not the best security to use.

The third type is a universal transmitter, designed to work with many receivers. These have instructions for each receiver that must be followed exactly. Currently, the most popular of these brands will program 18 different receivers. These still do not cover all of the receivers made for gate operators so make sure you know before you buy one, what exactly they work with.

As always, if you have difficulty, please give us a call or e-mail and schedule an appointment.
