Garage door opening/closing on it's own
I have an "Overhead Door". When the electricity goes out, the door opens and stays open until the electricity comes back on. The door opens whenever it wants to, but I have to shut off the power to the garage (via the circuit box), then turn it back on, then close the door by remote or button on the wall. I also noticed that one of the senor lights is green, while the other one is red. Any ideas???
