Chamberlain Liftmaster Sensor Problem
Lately the sensors on either side of my garage door have been randomly going out. Of course, the door will not close and I end up manually opening and closing it. Then, magically, 2 or 20 or 200 minutes later, the lights come back on and it's business as usual. Today it happened again and after messing with it for awhile and being late for work, it apparently still doesn't work. WTF?
Any help would be appreciated.
