Do Your Electric Gates Keep Opening and Closing? Fix Them Today!

Electric Gates Keep Opening and Closing

Does your gate act as it has a mind of its own? Do you need to hit the reset button to fix this ongoing problem regularly? In other words, do your electric gates keep opening and closing? Fret not, since today we’ll show you how to fix this problem!

Everybody knows how annoying it can be having a faulty gate. For this reason, homeowners must know the different causes of this issue. From having faulty limit switches to radio frequency interferences, we’ll go over how to fix these problems.

So, keep on reading to find out more!

Why Do Your Electric Gates Keep Opening and Closing?

Automatic gates grant homeowners a wide variety of benefits. That’s why to keep on enjoying these benefits, you must know how to fix this sort of problem.

There can be many underlying issues that may cause your gate to behave randomly, whether you count on an automatic swinging or sliding gate. 

However, when electric gates keep opening and closing, then there are four main reasons behind this problem:

  • Limit switches aren’t working properly.
  • Your DIP switches need to be reprogrammed.
  • There’s an interference with the opener’s radiofrequency.
  • Your gate’s loop detector starts to have problems.

Limit Switches Aren’t Working Properly

Being one of the main features that grant gates their automatic feature, limit switches are the ones responsible for opening your gate. In other words, limit switches act as sensors. These switches detect if there’s an object or not in the way.

Because a limit switch can sense when there’s an object nearby your gate, it tells your opener when to start; thus, it moves the gates. 

For this reason, when your automatic gate begins to operate on its own, then it probably is because the limits switches start to become faulty. In other cases, it can be because it’s hitting any obstacles when it starts to open or close the gate.

How to Check If Your Limit Switches Are Working Properly?

One way to test if your limit switches are working properly is by using a limit magnet and a multi-meter. Usually, both these things come with your gate opener kit. 

First, you’ll need to open your switch. When opening your gate switch, you’ll see three wires from three different colors: white, blue, and red. While the red and blue are phase wires, the white wire is a common wire.

Take the white wire and connect it to the negative terminal of the multi-meter. In other words, you’ll need to clip it to the multimeter’s black wire. On the other hand, you’ll need to connect the other two wires to the multimeter’s red wire, which is the positive terminal.

Then, you’ll set your multimeter on continuity mode. There are two types of readings that can come up since it depends on the kind of switch your gate counts on. If it’s a normally closed (NC) switch, then the voltage reading will be of 1.5V. Otherwise, if your switch is Normally Open, then the reading will be of 0V.

After taking these readings, you’ll take your permanent magnet and place it near the switch. If your switches work perfectly, then this will make the voltage change. With an NC switch, it will make the reading change to 0V. With an NO switch, it will turn the voltage to 1.5V.

Lastly, keep in mind that you’ll need to do this with both halves of the switch, the top half and the bottom half. 

DIP Switches Need to Be Reprogrammed

When counting on an automatic gate, you’ll likely need to reprogram your DIP switches from time to time. After all, these switches are an essential part of your gate’s control board and opening mechanism. 

There are other times that programming correctly from the start can save you from gates that keep opening and closing on their own accord. Also, DIP switches are inside your remote control’s control board.

In a control board, there are between 8 to 9 different DIP switches on a circuit board, depending on the type of transmitter. Each of these switches can be placed in three different positions: positive, neutral, and negative. 

As you can imagine, each switch counts on their specific goal for your automatic gate. For instance, the first switch controls the gate opening limit. The second, third, and fourth switches take care of the opener’s auto-close timer. Be sure to consult the purpose of each switch with your gate opener’s manual.

How to Program for Single Entry Transmitters?

First, you’ll need to remove the transmitter’s front cover. Slide the cover away for you to get a look at the battery and DIP switches. 

After that, you’ll need to set the code by adjusting the switches. When adjusting them, be sure to use a small screwdriver. 

With a single entry transmitter, there should be 9 different DIP switches. Just like we stated before in this article, each switch can be placed into three positions. Adjust the switches to your liking by using the opener’s manual as a guide. Also, be sure NOT to place all switches in the same position.

Then, you can reassemble the transmitter once you have your personal code all set up. 

Now it’s time to place the code onto the control board’s memory. First, you need to remove the control box lid. Be sure that it’s set onto programming mode. That way, you’ll make sure that you’ll place the code onto the operator’s memory. 

To place your control board into programming mode by following these three steps:

  1. First, you’ll need to turn off the main power switch by pushing the switch that’s placed on the control box’s bottom right.
  2. Then, you’ll need to hold down the S5 button that’s on the control box as well. While doing so, turn on the main power switch by pushing the switch button on the left.
  3. Lastly, you’ll let go of the S5 button right after turning on the main switch. After successfully performing these three steps, your control board should be in programming mode.

Lastly, you’ll press your transmitter’s button until you see your control board LED light turns on and then off. After that, you’ll let go of the button. By now, the code should be on the control board’s memory. 

How to Program for Dual or Triple Entry Transmitters?

Programming a dual or triple entry transmitter consists of almost the same process as a single entry transmitter. The only difference is that dual and triple transmitters count on 8 DIM switches, instead of 9. 

You’ll start off by removing the transmitter’s cover. Then, you’ll set on the code in the same way you would with a single entry transmitter. You’ll also need to place your control board in programming mode as well in the same way as we explained before in this article.

Radio Frequency Interference

Additionally, when electric gates keep opening and closing, it can be due to something that interferes with your gate’s radiofrequency signal. 

Many things can interfere with the radio frequency of your garage door. Some of these things often include a home’s circuit board, AC systems, and even Wi-Fi.

Homeowners must first find out the source of the RF interference. If it comes from a device that you can do without, then it would be best if you disconnect it. However, if it comes from your neighbor’s appliance, you should consider telling them,

Lastly, you can buy surge protectors, higher quality remotes, or even an upgraded opener.
