have the liftmaster 8550W door openers - 2 of them. one works fine and connects to the MyQ Gateway so I can open it remotely from my phone.
The other door functions properly from the remotes and the keypad....however, on the opener itself, the button in between the up/down arrows is flashing half blue half green....and that door won't connect to the MyQ gateway.
What is causing this, and how do I fix it? I've tried the triple reset. To no avail. Can reprogram the remotes again, but same thing still happens.
Blue/Green light is flashing on that button. Read in the trouble shooting book something about it is attempting to connect to wi-fi, but have no idea what that means, or why it's doing it, or how to stop it.
Thanks for any help you can offer!
