I recently installed a garage door opener in my new home, it is wired as such per the installation instructions.
The garage was prewired with 20AWG, insulated and drywalled, and I identified which wires go where by testing continuity. For the first couple days everything went swimmingly, then suddenly the button stops "working". The opener is responding to the wireless remotes and it responds to the wireless keypad, however the button doesn't trigger an open/close event.
The button light is ON, and it switches off when the button is depressed, then switches back on when the button is released however the singal doesn't seem to be making it to the opener. It is on warranty, so I called and they sent me a new button, however I am not sure thats the problem.
I tried shorting the red and white wire from the button because thats how I opened the garage door at my last house (the button was smashed, just had two wires hanging on the wall that I touched together), however shorting the wires did nothing.
I am thinking there is probably a bad relay in the opener. Or maybe the door button for this model does something special? What are your thoughts?
Model: Chamberlain LW3000
