Most Common Problems with Gate Motors Top 10

No1 *Problems due to cold weather and low temperatures

There are several problems your gate might experience when the low temperatures strike. You might notice some delay in opening of your gate, or even the inability to open at all.

Metal components will contract as the temperature drops and unless you are using grease specially intended for lower temperatures, the grease will thicken, too. All this makes it harder for the gate to move and open since it requires more power.

Another problem is the battery since it is inside a metal box. Due to this, as the temperature gets lower outside, the internal temperature of the battery will also drop and this will make it harder for the battery to start because of the reduction of the electro-chemical reaction. This reaction is meant to produce the electrical current which allows the gate system to operate.  You may have noticed that if you try to open it a couple of times, it will finally work.

No2 *The gate is not reacting, moving or making any sound

  • First you should check if the breaker and the switch are working properly.
  • Check the outlet in which the gate is plugged. You can use some other device to see if they work when plugged in the same outlet.
  • Then look at all your outlets to see if their ground fault interrupter is tripping. You have to check all of them because if GFI is tripping this action will cause power to be cut from any device in the GFI’s circuit.
  • The problem might be the remote controller, maybe it’s broken, the batteries are dead and need replacement or it has run out of its “working hours”.

No3 *The gate doesn’t stop where it is supposed to

If your gate doesn’t stop where it is supposed to it is mainly due to the limit switch nut or cam failing to hit the limit switch at the designated time. If you have a slide gate you’ll notice that a lever is holding the limit nut in place. It’s riding inside the slots of the limit nut. To solve this problem you have to press it back out of the slot on the limit shaft. This will put it back in its correct place.

No4 *The gate doesn’t open unless there is someone standing next to it

This problem can occur in two scenarios.

  • One reason might be the antenna which was cut or just shortened. Try to put it as high as you can and be careful not to let it touch any other metal surface.
  • The other might be that some other source of transmitting is interfering with your source. Check to see if there is any possible source of radio transmitting near where you live. This could be a radio station, a military base, a flight path or an airport. If it happens that you do have these sources near you, then you will have to get a special receiver and an antenna.

Check the face of your receiver cover. It is common that gate openers have separate receivers. Look for the names like Multi Code, Liftmaster, Linear and Mega code. Check your remote clicker because it will have the same name as the receiver cover does. While pressing the remote you should listen and wait for the click coming from the rec receiver.

No5 *The gate doesn’t close

  • Check to see if there is something blocking the gate physically. Check the wheel bearings to see if they are broken and check the chain and track too to see if they is any visible damage on them. For a swing gate you should check the gate arm for damage, as well as the hinges since they could be stuck or even broken.
  • If you still can’t find the cause then do the next thing. After making sure that the power supply is off, detach the chain for a sliding gate or detach the gate arm for a swing gate. Now try to move the gate to open/close it. If it can be done it means that there is nothing mechanical causing the problem. If you can’t move it means that there is a mechanical issue involved and that it would be smart to call a professional technician.
  • First check to see if any of the other house residents have maybe entered the “hold open” command and you didn’t know about this.
  • Then you should check for the key switch. Maybe the corrosion took its toll on the electrical switch on the back of the key cylinder, or the fire department came to your house without you knowing it to test the fire department key switch and they simply forgot to put it back to its regular operation.
  • This problem can also occur when devices like the photo eye or any other are preventing the gate from closing. You can check to see if the photo eye is working properly. First check to see if the safety LED light is lit. You should find this light on the opener control board. Look at the reflector if you have one. Maybe it is misaligned or even wet. By waving your hand in front of the photo eye, you will find out if it is working properly or not. The clicking sound means that everything is in order. Sometimes insects can cause malfunction of the photo safety sensors and control boxes since they prefer warm places. You should check from time to time and clean them with a dry cloth.
  • You should check the edge transmitters. These will be found on the gates with reversing edges. There could be a battery issue which means you will have to change the battery. Make sure you buy the right type of battery depending on the type of your edge transmitter. If there is nothing wrong with the battery, then the problem is the transmitter itself. The corrosion might have gotten to it or if it might be damaged in some other way. You would have to replace that transmitter with a new one if this is the case.
  • You should use the breaker to cut all power off. This action will automatically cause the gate to be released. Make sure to look at the loop detectors when you turn the motor on. The lights on the loop detector will tell you if you have a loop problem. It is possible that something is putting pressure to the loop too. If the lights are lit red, then you’ll know that you have one of these two situations on your hands.

The best way to get your gate fixed is certainly to call a professional technician to fix it.

No7 *Remote controller doesn’t work

As on any remote controllers, there is a little red light on the top part of it. This light will be lit when you give a command to the gate to open or close. If the light didn’t lit up when you pressed the remote key, then you problem can either be the batteries or the life span of the controller. Try changing the batteries with the new ones. If the problem continues after you have replaced the batteries then it is obvious that you need to buy a new remote controller since the old one has probably run out of its “working hours”. You can call a technician or a supplier from who you bought it. The technician will program the new remote controller and your problem will be solved.

No8 *When to use Manual Release Mode?

There will be situations when you will have to put your gate into manual mode. You may experience a power outage or your gate isn’t working because it’s broken or you forgot to do an annual service and it’s showing difficulties in its operating. If the power is off this mode will allow the gate to open and close. You should have a manual release key in your possession and the gate should have been tested to see if it works in manual mode.

No9 *The swinging gate doesn’t open

There can be three causes for this problem.

  • The first one is because the remote controller is broken, its batteries are dead and they need replacement or it’s just run out of its “working hours”.
  • Then it could be your ascending driveway’s fault. If this is the situation you are in, then either make the gate open to the other side if it’s possible or just hang the gate to a higher post so it doesn’t reach the driveway as it opens.
  • Since the gate safety loop sensor is present at most gates, you should check it to see if this sensor is the cause of malfunction. It is made to prevent the gate from harming any person, animal or object that might be on its path. If the sensor notices an obstacle it reverses the gate process/disables it. If the sensors aren’t working properly, you should call a technician.

No10 *The gate keeps making a beeping sound

If your gate keeps beeping, especially during the night after the storm and making battery low sounds, you should try to add one more battery, that is, more power. It is possible that after the storm your battery might make sounds as if it is dead but the next day everything will be fine. This might occur with Mighty Mule Gate openers. If the trick with adding the second battery doesn’t work, then you can just contact the company’s customer support.
