Have been using the 888LM for 4 years now.  Never had any issues before, but just last week it started to act up.  Garage door suddenly open and close without warning.  Almost closed the door on my child!  It would randomly open and the controller stopped working.  When I press it, would not close the garage at all.  The original remote control still works so is something with the 888LM.  I have unhooked it and try to reconnect.  After re-connecting the 888LM it would now sporadicly open-close-open-close-open-close (not even fully) the garage door again and shaking the whole garage.  Felt like the entire garage door would break from this.  I had to disconnect it for now as is completely non-functional. Please help.

See posts by others, there's many, such as this one where the user seems to have figured out the cause.
