Everyone in this thread, can you please post the EXACT model of your board, and the configuration you are using that works? There is a lot of different boards out there and I’d like to update the main post with solutions that work to save people from reading through all these comments
Also, what is a good name for the Yellow/White wire method?
Myself
- LA400 Opener
- Single Gate
- 001D9040-1CC REV B control board (Circa 2019)
Yellow/White Wire Method did NOT work
Liftmaster K1D8080-1CC Expansion board did NOT work
