Did it short out? The app isn't working either suddenly. It indicates door was closed despite it being open. Did the wall unit fry?
It's an 888lm
Lastly, can I get a new wall controller with motion sensor and use my original internet gateway? Sad
Same problem - came home to find the garage door open. No lights on 888LM wall unit. However all wireless units work fine. It's about 8 years old.
Here's a clue: a car accident down the street, took out a power pole. My power was out for about 20 minutes. No other electronics were damaged in the house.
Assuming I need to replace the 888LM.
Why would this event have caused the door to open? I can accept that the power problem fried the wall unit (maybe a power surge during the accident?) but it would be best if it did not open the door. Security issue!
I just had the same issue. It corrected itself 2 days ago, and now the same thing happened today while I was at work. Door opened, no power to panel. Terrible for security. I called and was told the capacitors are known to fail in 888LM, and that you have to buy a new one. Why isn't the company covering this issue and replacing faulty units for customers that have the problem?!! Liftmaster / Chamberlain really should take responsibility for this known defect and make customers whole.
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.
I have been posting my above comment on as many threads I can find to try to help people solve this issue. I have been seeing some responses from Chamberlain reps, but I cannot confirm that anyone is making any progress with Chamberlain. If you have an 888LM and are leaving town for a period of time, I have several suggestions: 1) Disconnect your 888LM from your garage door motor and use your old remote to open and close the garage. 2) Unplug your motor and/or lock your garage door in the closed position. 3) Go to the local hardware store, buy a "dumb" button (less than $10) and replace your 888LM.
No support options, and the forums here are heavy on "someone will reach out" and void of any Chamberlain knowledge in the knowledge base.
Chamberlain Mods: Whom do we send the bill to if we need to do a self-help replacement? I need to be able to open/close and secure door all seven days of the week, especially on holidays.
