Liftmaster 8500

MyQ door controller 888LM

This is the illusion of security.

Actually the opposite of security.

Upon failure, the door defaults to open.
Then the controller dies.

Letting our 3 dogs out.

Google 888LM Problems

They have know about this for years.

There is no solution.

Turn the power off anytime the door is closed and you want it to stay closed.

My best advice.

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( 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.
