Good morning. It’s 2:42am and my 888LM control unit for the garage door is beeping and flashing red and yellow lights. Needless to say I can’t make it stop and I cannot sleep. I need immediate help
My fix was to replace the 888LM and the problem went away. I then repaired my 888LM door opener by replacing the two capacitors in the remote and tested. I have now repaired a couple of these remotes and all are still working. I don't recommend repairing them if you don't know how to use a soldering iron.
