Safety: Test the Safety Reversal After Installation
A garage door opener moves a heavy door, and its safety systems need to be set up and tested correctly.
- Make sure the door is properly balanced before connecting an opener. An opener is not designed to lift an unbalanced door.
- Install the photo-eye safety sensors no higher than 6 inches above the floor.
- After installation, test the safety reversal: the door must reverse when it meets an object on the floor.
- Keep remotes away from children and never let anyone walk under a moving door.
Follow the LiftMaster installation manual, or have a garage door technician install the opener.
Frequently Asked Questions
What does “3/4 HP equivalent” mean?
LiftMaster rates DC motors by comparison to AC horsepower; DC lift capacity is not measured in HP. The figure compares the 2420L’s lifting capacity with a conventional AC opener of that rating.
Does it work during a power outage?
Yes. The included 485LM backup battery lets you open and close the door when the power is out. Replace the battery every few years to keep it reliable.
Can I add more remotes or a keypad?
Yes. See our LiftMaster remotes, keypads and wall controls. Check that the accessory supports Security+ 3.0 before ordering.
Do I need professional installation?
Many owners install their own opener, but the door must be balanced first and the safety reversal must be tested afterward. If your springs or cables need work, have a technician handle that part.
How is it shipped?
It ships by FedEx, or you can collect it from our Sacramento or Santa Clara store. See our shipping policy for current rates and dispatch times.
