Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
over the weekend we had a lightning strike that knocked out my Garage Door Opener. The wall panel has no lights on it. The main unit still has the green light on it, and seems to be powered (it was on a surge protector). The remotes also don't work, nor does the outside keypad.
Anyone got any ideas?

Was the surge protector one made special for door openers? (it would have lots of connections for safety eyes etc. not just a plug in?
If not you probably have blown safety eyes or circuit board.
Hope this is helpfull.
