Craftsman 1/2 HP Garage Door opened automatically and then closed
I have a 1/2 hp craftsman, don't recall model, but it isn't more than 2 years bought.
At 2 am. after being closed for 5 hours, the garage door opened by itself and 30 seconds later closed and 30 seconds later opened. I flipped the outside lights on and it stopped doing it. the green light on the pad was steady green.
What are the chances of a Thief being able to descramble my code or someone new in the neighborhood driving by and having the same code all of a sudden? I promise, I looked outside when I heard it and no cars in site.
The manaual says it may open and close by itself but what exactly does that mean. Out of no where it will just open and close a few times and stop and not do it again?
