The Genie 1/2 HP garage door opener is a heavy duty opener. When replacing the remote controls, the new remotes require programming. Programming the remote for a Genie 1/2 HP garage door opener is just like many other openers. The Genie uses a learn button that will store the code in memory. The opener can store up to nine remote control codes plus a keypad code. Unlike many openers, the learn button for the 1/2 HP opener is on the front face of the opener head instead of the rear.
Place a stepladder under the front of the Genie opener power head. Remove the two screws securing the light lens cover to the front of the power head with a Phillips-head screwdriver. Flip the top of the lens cover down and pull the bottom lens cover tabs away from the opener head. Set the cover out of your way.
Locate the learn button on the left side of the opener head, between the left light bulb and the edge of the opener. There is a small LED light underneath the learn button.
Press and release the learn button with your finger. The LED light will blink twice. Press the button on the remote control with your finger. If you have a remote control with two or three buttons, press one button only. The LED light on the motor head will stay lit without blinking.
Press the button on the remote control again and the LED light will turn off. Climb off the ladder, and press the remote control button once more. The opener will operate with the remote.
Insert the bottom tabs of the lens cover into the two slots on the lower face of the opener head. Flip the lens cover over and secure the lens cover to the opener head with the two retaining screws.
