I NEED TO FIND OUT HOW TO ADJUST A CRAFTSMAN GARAGE DOOR OPENER MOEDL # 139.53975SRT. ANYONE HAVE THE INFO? DOOR WILL NOT CLOSE EVEN THOUGH THERE IS NOTHING BLOCKING THE ELECTRIC EYES, THE LIGHT BLINKS AND DOES NOT CLOSE. IF I DISCONNECT THE DOOR FROM THE CHAIN DRIVE, THE MOTOR WORKS THROUGH THE CLOSE CYCLE JUST FINE.
