Liftmaster / Chamberlain 880LM Unresponsize

[spirtle1973]

A relative has a wall mounted CHAMBERLAIN 880LM "that hasn't worked in years." The unit has power but only displays "PRESS THE PUSH BAR TO ACTIVATE CONTROL SEE USER MANUAL". None of the buttons are responsive. Detaching the wires (removing power) and reattaching them does not resolve the issue. The garage door opener is a CHAMBERLAIN 45DCBR5 Any help is appreciated and thank you in advance.

It sounds like your Chamberlain 880LM wall control might need a reset or some checks. Try unplugging the garage door opener to reset it, and make sure all the wires and connections are secure. Check the wall control for any physical damage or stuck buttons. If you can, test with a different wall control to see if that fixes the issue. If none of these steps help, consulting the user manual or reaching out to Chamberlain’s support could be your next best move. Good luck getting it sorted!
