I replaced an old Chamberlin garage door open with a Linear LDO50 motor. I have a Chamberlin garage door opener keypad (model unknown) mounted on the outside of the garage. I’m trying to program the keypad with a new PIN. Doesn’t seem to be working. I pressed the learn button on the Linear motor, keyed a PIN into to the keypad and held the enter key down. The Linear motor times out in 15 seconds. The instructions on the Chamberlain keypad says it may take up to 30 secs to set the PIN.
Is the Chamberlin keypad compatible with Linear motor?
