Typical setup is between 5 and 15 minutes.  Monitor your garage door, see how long it has been open, close it or open it, get optional alerts and notifications, and so much more.


No power?  No problem.  The Liftmaster WLED includes a battery backup system that kicks in when the power goes out! It uses a 12V DC battery that is always charged and ready, using a continuous trickle charge. This opener uses an audible signal to alert you when the battery is in use. Safety and security features still operate, ensuring protection during a power failure. Backup power also operates the opener for up to 40 full cycles in a 24-hour period.


The DC motor provides the homeowner with the quietest garage door opener on the market.


Time and Temperature Display

This model features a wall console with a motion sensor that automatically turns the lights on for you, and an LED time and temperature display. The wall console also has an adjustable light time delay. It is also equipped with an automatic maintenance alert system that scrolls any error codes on the LED display. It even has a lock feature that allows you to lock out anything that is programmed to the unit while you’re away on vacation, or in case of emergency.


Lifetime Warranty Belt

Similar to a camshaft belt, this model of garage door opener utilizes steel mesh inside of a quiet and durable belt. This prevents you from getting the steel on steel grinding, while maintaining the durability and longevity of a chain.


Lifetime Warranty 3/4 HP DC Motor

This is what separates our belt drive from the rest. Permanent lubrication through steel enclosed gears, with self-adjusting force and limits. You can see AND hear the difference.  All other openers use exposed plastic gears that wear out every 4 to 8 years. This motor ensures a longer life and smoother operation than any other garage door opener.


Other Features

Our Liftmaster garage door openers include rolling code security technology, infrared safety reversing sensors, and 2 multi-function remotes. They have auto force settings so that the garage door opener adapts to weather and changing environmental conditions, and internal electronic limit settings. It has a one-piece solid steel T-rail with an automatic belt tensioner on the trolley. The new energy-efficient operation consumes up to 75% less power in standby mode. Also features a built-in surge suppressor.
