It is surprising how many items you use each and every day that require electricity. What is more surprising is how you seem to forget what you can and cannot use during a power outage, such as a garage door opener. During a power outage, you must manually open and close the garage door. An emergency release cord on the garage door arm opens the trolley to allow you to disengage the garage door from the opener. Once the power is restored to the garage door opener, you must reconnect the opener to the door. Close the garage door once the power has been restored. The door must be in the closed position to reconnect the opener. Press the garage door opener button. If your garage door opener has a button that opens the garage door and another button to close it, press the "close" button.
Allow the opener to operate without interference. The chain will move the trolley until it connects with the arm attached to the garage door. Some garage door openers’ trolleys and arms do not automatically connect. These openers require you pull the emergency release cord toward the garage door to reconnect the arm to the trolley.

When the lights came back on, everything in the house seems to work fine, except the garage door opener. When I press the button, I hear a 'click' from the opener (sounds like a solenoid switching) but the motor doesn't turn on & the door doesn't open. There's a little LED flashing on the back of the unit (I've never noticed it before, so I'm guessing it doesn't normally flash).
Did the motor get fried? Or is there some kind of breaker/fuse in it that tripped? It's a LiftMaster/Chamberlain, at least 10 years old. (Haven't been able to find a model number yet) Your circuit board might have gotten fried, your safety switches might be out of alignment. Try to unplug it for a minute and plug it back in. Thanks, that didn't work. I'll probably have to call a repairman. If the model number isn't visible, look under the covers for the lights. If that doesn't help, there's a diagram on the Chamberlain web site, as well as a form for tech support. I'm about to order my third circuit board, the first one having been replaced under warranty. I'm trying to figure out whether it was a power surge, or a short by a spider or other bug. As I recall, replacing the board was relatively easy (at least on my model), with realigning the sensors and reprogramming the remotes being the biggest hassles. I know this is an old post but I'm trying to find out why my genie door opener is having the same problem.
I replaced the entire unit because it was original to the house when we bought it and had this problem originally and still have the same problem;loss power and door wont open-manually open door and unplug unit for a few seconds and it works fine till next power outage.With my second unit I called genie tec line and a new circuit board was sent to me but didn't fix it so thinking it has to be something with a door sensor or limit switch but everything checked out.Could it just be these products suck?Was my old unit and my new unit just set up improperly somehow?Its just really annoying. I started using small square single surge protector, one for each door, after that happened. Stanley sent me a new circuit board and I haven't missed a beat in twenty years or more. It was east to install if you just follow the directions. Start with unplugging the unit. That's probably what we'll do. Unfortunately, when we first wired up the garage (many years ago), we installed a combo switch/outlet for each opener.
