7 Common Liftmaster Gate Opener Problems

Liftmaster Gate Opener ProblemsWhen counting on electric gates, it’s only natural to expect convenience at all times. That´s why it can be quite dreadful when your gate opener starts to malfunction. Today, we’ll go over which are the most common Liftmaster gate opener problems homeowners experience and their best solutions!

Top Liftmaster Gate Opener Problems and How to Troubleshoot Them

While there’s a variety of electric gate types, all automatic gates work by using many mechanisms. As a result, there’s no definite reason why a gate opener might start to break down. Additionally, some of these issues can be prevented and fixed on your own, while others might need professional repair.

When counting on a Liftmaster gate opener, then you can check its control board to see its error code. While these codes vary from model to model, they can help you figure out what your gate opener might be experiencing.

Use these codes and your opener’s user manual to get yourself an idea of what the issue might be. Today we’ll show you which are the most common problems you might encounter.

These are 7 Liftmaster gate opener problems you should know of:

  • Dirty or unaligned photo eye sensors
  • Faulty edge transmitters
  • Gates keep opening or closing
  • Malfunctioning or broken remote control
  • Worn-out, dirty, or noisy track
  • Damaged chain wheel bearings
  • Bad wiring at the control box

Dirty or Unaligned Photo Eye Sensors

Your gate’s photo eye sensors are the ones that tell it if there’s an object nearby when opening or closing it. They help prevent your gate of closing while your midway through.

These sensors work in a way that if an object is in between these, then your gate won’t close. Because of this action, if the lenses are dirty or unaligned, then it’s likely that your gate won’t work properly.

Luckily, you can fix this issue by yourself. First, you’ll want to make sure that both sensors are properly aligned.

If you count on the LMTBU model, then you’ll see that both emitter and receiver emits lights. When it’s not aligned, then the receiver will give you a red light. On the other hand, the Liftmaster’s LMRRU has a reflector and a sensor that emits a red light if improperly aligned.

You’ll want to gently rotate the receiver until you reach its sweet spot when lined up. You’ll know this when the light switches blue. Be sure to check if the sensors are stable enough. If they aren’t, then contact a professional  to help you out.

When cleaning the photo-eye sensors, use rubbing alcohol and a lint-free cotton cloth to rub the lenses.

Faulty Edge Transmitters

Just like the photo eye sensors, edge transmitters help automatic gates to detect any obstacles that may be on the way. Whenever they detect something in the way while it’s closing, they stop and reverse. Sadly, when this problem happens, it’s likely that your gate stays in an open position.

You can fix this problem by replacing your battery. Although you can do this procedure by yourself, it’s best for you to contact an expert technician to do it.

Gates Keep Opening or Closing

Do your gates keep opening or closing? When finding yourself in this situation, there may be four main causes behind it: faulty limit switches, unprogrammed DIP switches, radiofrequency interference, and malfunctioning loop detectors.

Luckily, if you have expert hands, then you can fix this problem.

Malfunctioning or Broken Remote Control

Many times, it can be that it isn’t your automatic gate itself the source of the problem. In fact, it can be your remote control.

You can check if your control is working correctly by looking at its light. If it isn’t flashing a red light when pressing any button, then it probably means that its batteries are out of charge. Replace them with new batteries if this is the case, you can .

If replacing them didn’t work out for you, then it probably means that the controller is now broken. When finding yourself in this situation, then you can either fix the controller by taking it to a professional or you can buy yourself a new one. Also, be sure to get your remote controller reprogrammed by an expert.

Worn-Out, Dirty, or Noisy Track

Worn or dirty tracks can be a common problem if you’re counting on a sliding gate. When your gate track is full of debris and dirt, then it can make your gate all jerky and not open smoothly. This issue can make your gate motor wear out too at a much faster rate.

That’s why homeowners must keep their tracks clean at all times. Be sure to also maintain your tracks well-lubricated as well. By doing this, you’ll also prevent a noisy gate.

Damaged Chain Wheel Bearings

You can find wheel bearings on swing gates. When these bearings break down, then it can make your gate not move at all. This sort of issue usually occurs due to a lack of lubrication, collisions, or severe weather. Faulty wheel bearings can also result in faulty hinges as well.

Just like your tracks, be sure to lubricate thoroughly your bearings and hinges using an appropriate lubricant. Avoid using petroleum-based lubricants.

Bad Wiring at the Control Box

Lastly, we have bad wiring issues. Unfortunately, this issue isn’t something you can fix by yourself. You can verify if it’s a bad wiring problem by checking the key switch and Hold Open commands.

If these settings aren’t set and your automatic gate still doesn’t work, then it’s time to call the professionals.

Now that you know the main Liftmaster gate opener problems, it’s time for you to take action to solve your issue. Remember that you can never go wrong by contacting your gate provider to handle any complications.

Also, in case you’re in a hurry and need to use or move the gate, then we recommend for you to change the gate, then be sure to switch it onto manual mode. By doing this, you’ll have a temporary solution while you get your opener fixed up.
