My Falcon 2 pro burner has no more power

I am sorry to hear that. As I have the same problem and the official support is not reachable for me, I’d like to point you to my own thread where people compiled some ideas what to do: Falcon2 22W lost more than half of its power - #7 by RodriguezLosWochos
So I don’t have to copy it all here.

Hope that yours is just a temporary problem.
