If your garage door opener is acting up and you need to reset it, there are a few things you can try. First, make sure that the power is turned off to the unit. Next, locate the learn button on the back of the garage door opener. Press and hold this button for approximately six seconds until the light on the unit begins to blink. Once it starts blinking, release the button and then press it again. The light should now be solid, indicating that the garage door opener has been reset. If this doesn't work, you may need to consult your owner's manual for further instructions.
