Roy, it could be a bad contact in the little memory pushbuttons or a loose wire. Sometimes a failure can occur just from the normal opening and closing of the door. Otherwise there are these little resistor pots on the motors but I'd thiink that you'd only lose one memory function like forward/back and not all. Lastly, the controller box may possibly be the culprit. Good luck!
