Craftsman Garage Door Opener Problem
I have two Craftsman garage door openers (About 20 years old - doesn't have any safety devices)- one for each garage door. They have been working fine until recently. But now one of the garage door opener doesn't open or close from the button on the wall or the remote or from the "remote link" in the car. It opens and closes randomly on its own! Only consistent way it goes from close to open or open to close is when I power cycle the unit.
This gets more confusing as the other door opener works ok with the button on the wall but the remote for it behaves "strangely" - sometimes it operates that door and sometimes it operates the other one! No DIP switch settings have changed. I'll appreciate if anyone can help me understand this problem and offer a solution. Thanks
