Hi, I had a similar issue last night. My garage door just opened on it's own and wouldn't close and the button is dead. I ended up having to remove the 888LM and used a remote to close the door. This is a huge issue for them. They are offering a free replacement here(https://www.liftmaster.com/888lm-myq-wall-control/p/G888LM#spec) and have extended the warranty through 2023. I have 2 of these units, so I'm not sure what to do with the other one yet, but I'll update if I figure it out.
