Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Given that it's working well I wouldn't sweat a little hum. It could be a relay or a transformer making a little noise. Not a cause for concern.
