888 lm no power on wall switch suddenly

  • Question
  • Updated 4 days ago
Garage opened on its own and there is no power showing on wall switch. If I disconnect it everything seems to work but when it's connected back up nothing works.

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

The same thing happened to me this afternoon. Our garage door opened, and no power at all to the 888lm. Is there a fix for this?

Has anyone ever been contacted by support? This post is over 1 month and no one has reached out to me yet.

I had the same issue a day ago. Was out of town and very surprised to roll up the driveway and discover the door open and the wall controller dead. Very frustrating and a glaring security issue.

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 replaced the 888LM wall button and it's all working now.

$50 for the part.


P.S.  Correction on age - the old one was 4 years old.

I had the same thing happen to me about a month ago. The door opened and now the 888lm is dead. I just found this thread while I was trying to get the unit functioning again. Did anyone determine what the issue was?

Wow... I just had the same thing happen an hour ago. My garage door opened on its own, and the 888lm has no power. My other garage door is working fine.

I contacted support via the chat function. They sent me a replacement control panel. Everything is ok once I replaced it. However, I have two of these so I'm wondering if the other one might fail soon...

Same problem on 7/18/18. Garage door open by itself, no power to wall mounted control. Had to use emergency cord to close door. This is a real security issue as I planned on leaving for a 10 trip tomorrow. In otherwords if I would of left today my garage door would of been up for 10 days. Very inviting for a theft.. and hard to explain to an insurance company.

I tested the dead 888lm. When it is dead with no lights. It can be use to open and close the door when you connect and disconnect the wires. An other word. At the moment of death, it opens the door. Super bad design!!!!!

My control panel just died after 4 years. The repairman says the 888lm has an internal battery that goes bad over time.

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.

Just happened to me. SDGE had a planned power cut off. Luckily the door was not open.
