craftsman garage door opener remote & key pad not work
I purchased a home & opener has no manual but I can push the button on the wall to open & close but the green lite is not displayed on the wall unit & the outside keypad doesn't work either as well as my remote. I have replaced keypad battery & remote battery & have also tried to re-set the codes but to no avail. I believe it must be something with the green lite on the wall unit not working. Can anyone advise?
