I have an 888LM which was connected to an 8500 liftmaster opener. My garage door opened in the middle of the night, and in the morning the 8500 started flashing 3 blinks (opener short). I've read of many people having this reliability problem. When I opened up the controller I can see fluid has leaked from one of the capacitors. This seems to be a widespread problem with these openers and a security issue as well. Has this been fixed in more recent 888LM models? Is Chamberlain standing behind these products and replacing them?
