hi todd, that is a manual transfer switch. the 3 position switch allows you to have all power off, shore power or genny power.
it is just some relays, so if it is humming, the relay coils are getting worn. it will not hurt anything to hum.
i had the same thing on my 90 and i totally rebuilt it with new relays. i have the part numbers i believe if you choose to do so. it is not hard, just time consuming and the relays are a little pricey. i got mine from grainger.
