Liftmaster offers a wide range of quality garage door products and accessories and provides plenty of support if you experience any problems with any one of their products. But there are a number of common problems you may be able to tackle on your own.

A general understanding of how a Liftmaster garage door opener works can help you identify problems and aid in Chamberlain/Liftmaster troubleshooting.

The door opener is either located on the ceiling of your garage or mounted on the wall. A pair of LED safety sensors are located on either side of the track, close to the floor. The sensors will prevent the door from closing if they detect something is blocking the path. A 16-gauge wire connects the sensors to the opener, which is powered by the electrical system in your home. If your door opener is not working, the first thing you should check is the power plug to ensure that it is plugged in all the way and transmitting power to the garage door opener. If it isn’t, check the main panel to see if the breaker has tripped.

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. Simply 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 that are on the motor housing. Then, to extend the close limit, turn the close limit dial counterclockwise and adjust the open limit dial clockwise in order to extend the open limit.

Liftmaster Remote Won’t Work

When you install 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 how to program your remote control. If your remote has been working for a while and stops working, the most common reason for this 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.

Liftmaster Error Codes

The latest Liftmaster garage door openers come equipped with a feature that will display an error code consisting of a series of flashing lights. The number of times the lights flash and direction of each flash determines what error is being detected. How to interpret the error code system is outlined in your manual so keeping it handy to troubleshoot error codes is important.

Below is a list of error codes for the Liftmaster 8550 garage door opener:
