My 888LM control panel is flashing and beeping
My 888LM control panel starts beeping with both lights flashing randomly throughout the day. The door does not operate while the panel is beeping. Unplugging the unit stops the beeping and everything functions afterward. Also, I have a very short range on all of my remotes.

Andy,
I am sorry to hear you are having a problem with your 888LM. The control panel should only beep when the door is trying to close via the app or the timer to close feature. Also, you mention that you have poor range on your remotes, did this happen when you installed the 888LM? I would like you to disconnect the control panel from the motor head, the wires reside in the red and white wire terminals, then test your remotes. Do you still have a range issue? Let me know. -

Once the control panel is disconnected the remotes no longer open or close the door. If I jumper the red and white the door will open and close. Oddly, after disconnecting the control panel and reconnecting it the remote control range is better for some reason.

If the MyQ control panel continues to beep randomly, please email me at MyQCommunity@LiftMaster.com. I am glad to hear that reseating the wires took care of the range issue.

I have a very similar problem. MyQ control panel beeps (3 times - tu-tu-tum) in random intervals while flushing red and yellow light at the same time. Between the beeps, the yellow light stays on. I disconnected both wires and after few hours connected them again and the panel after a while started to beep again. I can open garage door using panel or remotes, but the beeping is extremely annoying because the beeps are pretty loud and I can hear them in the house.

My opener is doing the same thing. Very annoying hearing the constant random beeping. Unit is not yet a year old

Dawn, I emailed you about a similar issue when trying to install the Lm888 onto a genie opener that is listed as compatible on liftmaster' website, it's a CM8600IC. However when I connect it to the wall cable it basically flashes yellow and red rapidly until I think it is charged (much more than 5 min as the manual says). Then beeps 3 times, then flashes slowly for a while. It never actually opens the door however. Is this not actually compatible?
