I would do what you've probably already done - closely inspect any connections and clean with alcohol to rule out poor connections. I forget if Kessil has a secondary fan output that could be used...or maybe another 12V output? Sorry that thing is not behaving.Hello everyone, so I replaced the fan with the noctua fan recommended. The fan does not turn on. I thought maybe I should check if the Kessil original fan works outside of the light. Well it does. So the issue is probably on the board. I don’t know how to fix that. Any ideas?
