Simple Fixes

In many cases, there’s going to be an easy fix for your garage door opener. 

To help you get started, we collected a few things that might help you understand how to repair a Liftmaster garage door opener. 

Replace the Batteries

Most of the time, you’ll find that the batteries in your remote have drained over time.

If you’ve been using it for a while, this is probably why the opener won’t work now. 

Try changing the batteries out, and try again. It’s a good idea to check the connectors too. If there’s rust, you can polish them to make them work again. 

Lubricate the door

If a garage door isn’t properly maintained, it may not be able to open properly. Lubrication is an important part of maintenance. If you don’t do it, the moving parts may seize up or rust, stopping the opener from doing its job. Lubricate all the moving parts of your garage door, and try it again.

Plugin the Opener

Again, this is a very simple issue to address. The garage door opener can be unplugged, usually to allow you to work on the garage door safely. If it’s been unplugged, then, of course, it can’t work. Check it hasn’t been unplugged, and plug it back in if it has. 

Signal Issues

The next thing that can affect your garage door opener is signal issues. These will stop the garage door from opening or shut it again once it does open. Let’s take a look at what can be causing these problems. 

Get in range

Firstly, check that you’re in range of the garage door. If you’re too far away, your remote may not be able to send a signal to the opener. 

The garage door path is blocked.

Are you finding that the door won’t shut all the way? If it keeps moving down but then auto-reversing, that’s a sign that something is blocking the entrance. The opener has a safety measure that stops it from shutting if there’s something in the way. Check the garage door path for any blockages, and remove any you find. 

Blocked photo eyes

If you’ve checked for blockages and can’t find anything, this is probably the culprit. The photo-eyes are what sense if anything is in the door’s path. If either is blocked, it cuts off the sensor and forces the door to reopen. 

Most of the time, you’ll see that the photo’s eyes have got dirty, and that’s what’s causing the problem. Clean them off with a soft cloth and try the door again.

If that doesn’t work, the sensors may be misaligned. Tie a piece of string between them, and adjust them until the string is level. This will realign them and ensure that your garage door can open properly again. 

Crossed signals

Are you finding that your garage door opens even when you aren’t using it? That’s a sign that you’re getting crossed signals with someone else in the neighbourhood. They may have an opener on a similar frequency to yours, and when they try to open their door, they’re opening yours instead. You can check your manual to see how to change the frequency to stop this from happening. 

Hardware Repairs

Finally, there may be issues with the hardware of the garage door itself rather than the garage door opener. Look for these problems if you’re not seeing anything on the garage door opener causing issues. 

Broken springs

This could well be why your garage door isn’t opening. The springs on your garage door are designed to give it the tension it needs to open. If they don’t have that tension, the door can’t open when you press the button on your remote. Check to see if the springs on your door have broken or have lost tension. 

When checking the springs, remember that they are very dangerous when handled incorrectly. If a garage door spring breaks, it can launch and cause damage to anything in the garage. 

Worse, it can cause serious injury. If you believe the springs are to blame for the opener not working, you can replace them. However, it’s often best to call on an expert to help you, as they can remove and replace them safely. 

Bent or broken tracks

Another reason your garage door opener isn’t working could be your garage door tracks. These are what the garage door travels on, so they need to be perfectly straight. If there’s a bend or dent in them, you’ll need to mend them.

For minor dents, it’s simple to hammer them back out with a rubber mallet, a piece of wood. If the dent is severe, though, you’ll need to look into replacing your tracks. This is another job where you may want to call in a professional. 

As you’ve seen on this list, many repairs are essentially just troubleshooting. These are easy to do yourself, and so you’ll have your garage door opener working again in no time at all. 

If you’re having more substantial problems, though, or are unsure of what to do, it’s always better to call in a professional. Keep that in mind as you look for the problem.

Now that you know how to repair a Liftmaster garage door opener, you can troubleshoot the problem before calling a professional.

Problems With The Liftmaster Safety Sensors

Your Liftmaster garage door not working could be due to an issue with the sensors. As mentioned above, the sensors are there to prevent the door from closing if an object is in the path of the garage door. 

So if your garage door is closing partially and then opening again or does not close at all, your safety sensors should be the first thing you check. There could be something blocking the beam between the two sensors. If there is nothing obvious in the way, the problem could be that the lenses on the sensors need to be cleaned.

Also, check to see if there are any cobwebs on the door tracks, as these may block the light. For the sensors to work, they need to be perfectly aligned. If they are slightly off, it will cause a problem, and you will see a blinking light on one of them. Loosen one of the sensors and adjust its position until the light is no longer flickering.

A loose door track will affect the sensors and cause them to be misaligned. To fix this, use a wrench to tighten the bolts.

Liftmaster Close And Open Limits

You can use your garage door remote control to program and control the bulk of the motor functions, including resetting the open and close limits if the garage door doesn’t close or open completely. This can also be done manually on most Liftmaster models. 

To do this, you will need to locate the limit dials on the motor housing. Then, to extend the close limit, turn the close limit dial counterclockwise and adjust the open limit dial clockwise to extend the open limit.

Liftmaster Remote Won’t Work.

When installing a new door opener, the remote will need to be programmed and will not work until this is done. Your owner’s manual should provide instructions on programming your remote control. 

If your remote has been working for a while and stops working, the most common reason is dead batteries. Change the batteries and try again. If the remote still doesn’t work after changing the batteries, check if the lock switch is turned off if you have a wall-mounted model.

Beeping Garage Door Opener

LiftMaster garage doors that have a battery backup and are connected to Wi-Fi will beep to let you know about an issue or to confirm that a process step has been accomplished.

If your garage door has a battery backup, there are several possible beep scenarios:

  • Beeping every 2 seconds and an LED display that’s steady orange means the unit is using battery power. Is power restored in your home? Test the outlet to make sure.
  • Beeping at 30-second intervals with an LED display flickering orange indicates a low battery. See if the outlet will provide power when plugged into a different device. If so, the battery needs to be replaced.
  • Beeping every 30 seconds with a steady red LED display indicates a dead battery that needs to be replaced.

If your garage door is Wi-Fi enabled, most beeps you hear will be related to the opener’s status in connecting to the network:

  • Three slow beeps indicate that the opener is connecting to Wi-Fi.
  • Six fast beeps mean that the opener has failed to reach the server.
  • Two beeps will be heard when the opener attempts to connect to the MyQ server.

Garage Door Opener Lights Flash, But Door Doesn’t Close.

Your LiftMaster garage door opener features two safety mechanisms that could stop the door from opening or cause the opener lights to flash.

  • Check that the lock button on the main door control isn’t activated. When on, this feature will lockout requests from all garage door remotes and restrict operation to the main door keypad.
  • If the lock button isn’t activated, it’s likely that your garage door’s safety eyes, which ensure that the door only closes when the opening is clear, may be obstructed or misaligned. See this article for more help on safety eyes.
  • If your door comes down, hits the floor, and reverses, your safety eyes are likely the culprit.

Garage Door Opener Light Won’t Turn Off.

LiftMaster garage door openers are equipped with at least one light whose function is wired into the opener. Lighting is defaulted to remain lit for 4.5 minutes and turn off automatically. There are several ways to check whether you need to adjust lighting settings or that there’s a wiring issue:

  • Ensure that the light button on your Multi-Function door control hasn’t been accidentally activated. Press and release the button again to turn it off.
  • Have you been walking back and forth in the garage? It could just be that the safety sensors are being crossed and, because of that, the garage door light is remaining on.
  • There could also be a motion-detection feature. Check your owner’s manual and, if desired, follow the steps to deactivate this feature.
  • Your owner’s manual will also tell you how to reset the light time-off feature. You can reset it too as short as 1.5 minutes after activation.

When Was The Last Time You Replaced The Batteries?

Liftmaster garage door opener troubleshooting should always begin with the simplest, most obvious check. If you press your garage door opener remote and nothing happens, the best place to start is with the batteries. 

Open up the battery panel on the remote and replace them with fresh new ones. That might be as far as you need to go regarding repairs.

Are You Expecting Too Much From Your Remote Opener?

If you replace the batteries and it’s still not working, the next thing to ask yourself is whether you’re expecting too much from your remote. It would help if you still were within range of your Garage door Repair for it to transmit the signal. 

If you’re hitting the button from many houses away, you likely aren’t in range. Try using it once you are in your driveway and see if it works then.

What About Broken Parts?

If you’ve tried all these steps and the door still isn’t working, it could end up being that you have some parts that are broken and need replacing. The most common culprit is a broken spring. It may not even be broken – maybe it doesn’t create tension, which means it can’t work properly. 

Dented and broken tracks can be another issue preventing the door from working.

These troubleshooting tips will make it possible to fix your Liftmaster garage door and get it working again.
