Worked perfectly. Thanks. I couldn't figure it out for the life of me. Ya, have your garage door shut and set the up limit (hold the up button to the height you want -- hit limit) and then the down limit to the desired shut down position -- hold it in til you reach that downward floor position and press limit. Then, when the up and down limits are set, hit force to save the limits up/down and boom!!!
*omg my garage door doesn't open all the way. First try it didn't work. I unplugged, replugged and redo the programming again and it worked. Thank you so much!*
My guardian says 600SL. There's a white cover where yours is black and has controls. I wonder if that's under the white cover and if so, how do you get the white cover off?
