Sears Garage Door. Light won't turn on when door is opened/close
Hi all. I have a Craftsman garage door opener model 139.53910.
We recently moved into this house and it has been working fine. Recently, the light stopped coming on when opening/closing the door. I, obviously, suspected the bulb was burned out, so I changed it. No luck. The thing I can think of is that during a recent four-hour power outage, something may have been damaged...however, since the opener performs normally, I'm inclined to think it's something else.
Thanks in advance for any help you can send my way!
