I have a Sears craftsman opener. I followed all directions to set up. Some initial issues synching app but then worked fine.Wired it up. Used the app to open the door. Opened it great! Then wouldn’t work again…tried app, tried alexa both were showing me it was working but nothing happened to the door. I redid the wiring thinking maybe a wire came loose. Asked Alexa to open the door it immediately started opening. Asked her to close it nothing. Tried the app…nothing… So both times it worked just once than nothing…anyone have any ideas?
Immediately after the new command files, are you still able to use the wall button?
This could be the case of sticking relay:
