888LM dead, customer service won’t help. They told me I’d just have to buy another one! How are people getting theirs replaced? It died and left my garage open all day while I was away.
All of them. I called them when mine failed and the garage door started going up and down on its own. They had several years worth of production that have defective parts or poor quality parts. They would last about five years and then you would have problems. Actually surprised some child has not been killed when the door comes down on them. Chamberlain should be ashamed that they have not had a recall on this garbage and replaced the controllers for free. I actually bought a replacement, then found out about the issue, and they said if you would have contacted us, we would have replaced it. Guess that was a lie since they did not offer to replace yours.
Hi, I had a similar issue last night. My garage door just opened on it's own and wouldn't close. 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.
Our 888LM LiftMaster opener malfunctioned as well. We were on the golf course and our ring app alerted us of movement. I was shocked to find the garage door opening all on it's own. The garage door was open with no one home for several hours until we could get home to close. Major security issue!
