In this article, we will guide you through one of the most common reasons why a gate opener stops working: electrical problems.

This step-by-step guide is intended to help you figure out what is causing your problem and hopefully fix it. However, many issues with gate openers should be fixed by a professional.

LiftMaster Gate Opener Won’t Open – What To Do

This step-by-step guide will help you determine what to do if your gate opener suddenly stops working and won’t open your gate. One of the most common problems with gate openers is electrical issues. Electrical issues can be caused by a variety of factors – from small issues to much larger problems.

Step 1 – Check For “Hold Open” Command

Many gate openers have a “hold open” command. If this command is unknowingly pressed, it could cause your gate to stay open indefinitely or not work properly. Check all of the commands on your gate to ensure the “hold open” command or other possible commands have not been accidentally activated. Your gate opener problem may be as simple as an accidentally pressed button or switch!

Step 2 – Check The Key Switch

If the “hold open” command is not your problem, the next simple solution is to check the key switch. It is possible that the key switch has been turned to stop the gate from opening – for example, the fire department may have tested your gate and failed to put it back to your regular settings. A bigger potential issue with the key switch is damage or corrosion due to weather over time. If your key switch is damaged, don’t hesitate to call your gate installer to determine your options for repair or replacement.

Step 3 – Reset The Power

Like all electronics, sometimes all your gate opener needs to work again is a simple reset. A simple issue may have caused the malfunction and it is possible that resetting the power will bring your gate back to life. The video below also shows you how to reset the “loop detector” on a LiftMaster gate opener. This can also be easily solved with a reset.


Before moving on to more invasive steps, it’s a good idea to reset the power and see if your gate’s operation improves after the reset.

Step 4 – Check Sensors/Photo Eye

If you’ve come this far, that means your problem is not a switch, command, or a simple power glitch. The good news is that your problem may still be a relatively easy one to fix. When a gate won’t open, one of the most common problems is an issue with your sensors/photo eye. Check out the video below to see how to fix the problem. Though the video focuses on a gate not closing, the same issue can also cause your gate to stop opening.


If you are wondering if your gate’s sensor or photo eye is not working, follow these steps:

  • Check to see if the safety light is on (found inside the control box)
  • Check to see if your sensors are wet or if they have collected debris
  • Wave your hand in front of your sensor and see if it reacts – if it doesn’t, something is wrong

If you notice any issues like the above with your sensors, clean them thoroughly but carefully. Sometimes debris or even pests can interfere with your sensors, causing your gate to fail to react properly.

Step 5 – Check The Edge Transmitters

Unfortunately, if your problem is not fixed by any of the above solutions, you may have a bigger issue. Check your edge transmitters (if your gate has them, they are found on gates with reversing edges). When you check the transmitters, you will be able to see if there is an issue with the battery. A battery replacement is a relatively simple procedure, but it is best if a professional does it?for you. If your battery is fine, then there could be a problem with the edge transmitters. Weather damage or corrosion could have taken place over time, causing significant damage. If this is the case, you will need to replace the transmitter.

Step 6 – Call The Professionals

If you still can’t figure out what is wrong with your gate opener, then it’s time to call the professionals. It’s best that you do not go into the control box or attempt to fix any mechanical or electrical issue if you do not have the proper kn0w-how. You could create more damage that may end up costing you more. You could also injure yourself. Gate openers are complex pieces of technology and should be repaired by those who understand how they work.

Other Possible Causes

If you suspect that your issue may not be electrical – you could be right! There are lots of other reasons why a gate opener will stop working. Check for these other issues to help you solve your gate opener problem.

Possible Cause – Remote Control Issues

If your gate isn’t opening, it may not be the fault of your operator! It may be a simple problem with your remote control. If the remote isn?t flashing a red light when you press the open key it means it has probably depleted its battery or the controller has reached the end of its life.?Gate Openers Review suggests these steps for fixing this problem:

  1. Try swapping the batteries?with a spare and functioning remote. If the controller works then you know its a batter issue ? whew!
  2. If, even after buying or swapping batteries into your remote, the?gate?won?t open or the flashing command light isn?t appearing, then?the controller may simply be beyond its life expectancy. This is common in electronics and may require specialized tools and parts to repair.
  3. Call the supplier or a technical representative?to help you replace and program the controller.

Possible Cause – Weather Issues

We see pretty extreme temperatures in Ontario. Wet and rainy fall days or cold and icy winter weeks can cause damage to the gate opener or the gate itself, stopping it from opening properly.

Weather can also stop your gate from closing. So, how do you check if weather is the issue?

The first step to determining if your gate won?t open due to weather is by simply checking the weather!

Has it been extra rainy the last few days? Was there a significant drop in temperature? Has the cold set in for the first time this season, or has it snowed recently? Even?rain?can stop your gate from closing or opening properly.

Rain or snow can block your sensors or photo eye and stop them from working. In extreme cases, such as a heavy ice storm, it could physically damage your gate or gate opener. Keep an eye on the weather and maintain your gate opener as necessary.

Possible Cause – Something Is In The Way

Another?simple but common problem that may result in your gate not opening is that something is blocking your gate?s pathway. If there is debris or an object blocking your gate?s path, it will not work properly.

Check the area thoroughly to see if anything, even something small, is in the way. Debris can also cause your gate to get stuck in the open position. You should also regularly maintain your gate’s tracks and mechanical parts so that debris does not build up and cause bigger problems down the road.
