Character limit got me. After reading about this issue it seems it is way more prevalent than it should be. Wondering if LiftMaster has changed the design? Are capacitors the main issue? Do new ones have better caps?

I am still waiting on an answer about the capacitors in the 888LM? If I buy a new one am I getting the same design that is clearly failing at a high rate across the country?

Same here. Happened just Tuesday this week July 24th. My other 888lm failed six months ago and I had it replaced with a brand new one. The service agent told me of the known failure and that he had replaced 100 of them. I wanted him to replace both but he only had one with him that day. This time the failure was as you describe with both lights flashing and the door won't function. Last time the door was found opening on its own. I received a call from my neighbor that my garage door had opened wile I was away. Calling liftmaster now to see about warranty. My opener is a recall item and she is sending a new one out manufactured after the recall. hope this helps. 

Just call 800-528-5880 and they answer quick and solve the issue quick no hassles.
