My locking light continues to blink on the Premium control console of my Craftsman 1/2 HP model 139.53975SRT1. I lose my remote use and my keylock use after a day or so. My safety reversing sensors are solid amber and solid green. I can reprogram everything but it fails after a day or so. I press the small lock button for two seconds to unlock the console but it doesn't unlock. I have unplugged the power from the unit and restarted everything to no avail. Anyone else run into this problem. It all started a week ago when the door came down on a shovel that was in the way. The door stopped properly and went back up and that's when my problems started. The blinking light is very rapid.
