Converter & transfer switch problems
Can anyone tell me why I have a buzzing/hissing noise coming from my converter when there is no load on it? When I turn on at least 2 light the noise goes away. It's in a 2000 Southwind and it's a Int...

I've heard of things like the first problem due to the variable speed fan circuitry interacting badly with some fans that PD used at low power (and hence temperature) operation; the control circuit provided too low of a power to the fan motor or something like that. Some here were able to fix that based on advice from PD. At any rate, they generally have quite decent customer support, so calling them would be my suggestion.
Your transfer switch is sticking, which you already kind of know. It has one or two mechanical relays/contactors in it, and for whatever reason they're not operating freely when they should. Most probably the best solution is to replace it, even though it might be possible to clean or lubricate the mechanism. (If you're switching the power under load, it's possible that it may be the contacts arcing a bit and welding themselves together slightly. It's not wise to switch under load if it can possibly be helped; this is generally hard on a switch.)
