RE: Converter problem solution
Purchased a new converter on 9/18 before leaving for AZ. Fan never stopped running and it had high pitched sound. Emailed Progressive Dynamics; They responded almost immediately, declared it defect...

Seems like a lot of those PDs have a high pitched whine. Maybe a bad batch of some component. I assume the original was an older off the shelf model and the replacement is fresh from the factory.
