888 lm no power on wall switch suddenly

  • 16
  • Question
  • Updated 2 weeks 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?

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.

Same issue for me as well.  Just happened to my 888LM.  Came home to find my garage door wide open and 888lm dead with no power.  Remotes still work and app shows offline.  This is a major security flaw that needs to be addressed.  Is there a newer version of this panel that is compatible that does not have this issue?

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.

My 888LM evidently gave up the ghost @ 1230am, and on a Sunday no doubt. Like others, the failure resulted in OPENING the door vs leaving it closed (seriously, WTF??).
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.

Found This: Appears the good folks at Chamberlain are trying to get in front of this and have extended the warranty for 888LMs. Scroll down to Specs/Warranty:

Replacement Form: https://cloud.info.liftmaster.com/888LM

Kudos to Chamberlain for doing the right thing. Doesn't solve the immediacy of a failure, but good to know there's an resolution path.

Same thing - I have three LM888 controllers installed.  Built the house 4 years ago - first one went out about a year ago, cant remember if the door was open but tonight the wife and I came home to my 12' shop door wide open - needless to say we were a little freaked - but no incident - signed up for a replacement but reading these threads does not give me much confidence - will see

Just jumped on board the boat. So glad forums like this exist! Just went to bed and wife comes screaming at me that the garage door just opened and she can't shut it. Ordering replacement... Luckily, we still have one of the old original units that communicate directly with the opener. That shut the door. Also, when disconnecting the 888LM, I realized that the two wires connected to it need to simply be touched together to open/shut the garage door. Don't worry, low voltage, won't shock you (unless you're barefoot and standing in a puddle of water).
