Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener
I have replaced the battery. Still doesn't work. Has the wiring anything to do with the keypad. Is it possible that someone has disengaged the keypad?
No idea what you are talking about. is it a wireless or hard-wired keypad? Did you recode it if wireless. give more info.
