The 6 Flashes is a ' Force Reversal ' either the gate is hitting something or the rpm sensor in the motor arm has burnt out.
When programming the limits if this arm will only move about an inch when you press the button then that is a RPM sensor problem eitht he cables are broke or they have been shorted which will Blow the sensor which is built into the winding of the electric motor. Unfortunatly the only soloutions is to buy a replacement arm as this would not be covered by Liftmaster Warranty.
All i can say is check the cables or replace the cabl;e and re try the limit programming.
