Before you start disassembling everything, have you tried the system reset? I had similar issue when I bought my Sky earlier this year and was ready to replace the actuator. The system reset took 5 min and no tools. There's a YouTube video from watchjrgo that shows the process. I ended up doing it & the 3rd time it worked and have not had an issue since. Good luck whichever route you take.
