Opener Design

This garage door opener is equipped with a strong 3/4-horsepower motor that can lift heavy, wood, gatehouse-style doors as well as standard sectional doors. The belt-drive system helps the motor run smoother and quieter than a chain-drive opener. This is good news to sound-sensitive people and those who have a bedroom located over or near the garage as you won't have loud clanking and screeching coming from the LiftMaster 8550.

The best garage door openers offer timers to automatically close your garage door. The LiftMaster is one such opener with a timer-to-close function, which can be set to one, five or 10 minutes with the press of a button, or you can set your own custom time up to 99 minutes. This is a handy feature to have, especially if you tend to forget to close your garage door.

One of the best features of this garage door opener is the backup battery. This feature allows you to open your garage door up to 40 times if the power goes out at your home. The battery automatically recharges once the power is back on, so you don't have to worry about running out of juice or manually recharging the backup battery. This opener is compatible with the MyQ home automation system, and it works with HomeLink if you have an automobile newer than 2012.

Safety & Security

The LiftMaster 8550 Elite Series includes the standard safety features provided by the best garage door openers, including a safety infrared beam that projects across the base of the garage door and opens the door if anything crosses it. You won’t have to worry about kids or pets getting trapped under the door. The door is also sensitive to pressure, so the opener reverses and lifts the door if it encounters an object before reaching the ground.

The remote uses the Security+ 2.0 system, a series of over a billion rolling codes that resets each time the door is opened. This ensures that no one can hack your door code and access it while you are away. The control panel also has a motion sensor built in that turns on the lights automatically so you don't have to navigate through a dark garage.


The opener comes with just one 3-button remote and a digital Smart Control Panel that allows you to program the timer, clock and light duration. The digital display shows the time and temperature as well. Unfortunately, it lacks a keyless entry pad. (If you need one of those included, consider our top pick the Chamberlain Premium Whisper Drive.) You can add another remote control and a keyless entry pad, but you have to purchase them separately. It comes with two 100-watt light bulbs on either side of the main unit, so you’ll have plenty of light to get into your house. The lights shut off automatically 4.5 minutes after they are activated.

Warranty & Support

This opener comes with a generous lifetime warranty on the motor and belt, and it covers parts such as the railing and circuit board for five years. The backup battery is only covered for one year, however, which is fairly standard. This is a nice warranty package that should provide plenty of security for years to come.

LiftMaster provides customer support six days a week, excluding Sundays, and can be contacted by email and phone. You can download installation manuals, which is very handy if you misplace yours and need to learn how to program a new remote or replace a part. There are also instructional videos and answers to frequently asked questions on the LiftMaster support site.


The LiftMaster 8550 Elite Series is one of the best garage door openers available and is a great choice if you have a heavy door or just want an opener that you can't hear through the whole house. Although it only includes one remote and doesn't have a keyless entry, its Smart Control Panel, battery backup and lifetime warranty help this garage opener keep your home safe and secure.
