the shore power is what's buzzing/rattling. When plugging into shore the top switch clicks on and starts the noise. I left plugged in for a while and it was providing power to the motorhome. After a little while it started to quiet down to like an electrical hum, but would get loud again from time to time. I went over to the switch and with a screwdriver pushed on the black switch in the middle that clicks in and out, and noise totally went away. So do I just need to replace that one.... And where to buy?
