Try Not To Be As Dumb As Me
If you have a Liftmaster garage door opener, and the light behind the push bar (on the switch) starts blinking, and your remotes then stop working … it might be something as simple as “somebody done pushed the ‘LOCK’ button”.
Which, apparently, causes the the light behind the push bar to blink, and the remotes to stop working! Who knew? I’ve seen that button on that thing for years now. No idea what it did. Never pushed it. Never read about it in the instruction manual.
So after about 3 weeks of no working remotes, and the damn light flashing at me every time I walked by, and pushing the button and running out of the garage AND stepping over the safety beam thing that stops the door WHILE ducking to avoid the door — about 30 or 40 times between me, my wife, and our kids — I finally remembered to look into this online, and found the answer in about 10 minutes.
As it turns out, guess what? Somebody had pushed the LOCK button! So by pushing it again, it was all fixed. The blinking: gone! The remotes: working!
So once again, we learn the valuable lesson that reading the manual often leads to fixing problems.
Hence, the acronym RTFM: Read The Frigging Manual.
Usually the “F” stands for a different word. See if you can guess what it is!
