We noticed, after we returned home from our last RV trip and plugged into our home shore power (we have a 50 amp plug), a humming sound coming from behind the panel that houses the Surge Protector indicator, inverter, generator, and tank indicator. The inverter is off so I don't believe the humming sound is from that. If I unplug from the power the humming sound goes away. I suspect it is the Progressive Power Surge making the sound. There are no error codes on the Progressive indicator panel and everything seems to be functioning. While not a loud humming sound it is annoying. How does one access the back of the wall to determine where the humming sound is coming from? Any thoughts would be helpful.
