Lucky I was able to call the fine folks at Tempa-Cure 1st thing in the morning and someonewas at my house before I ws supposed to leave for work. I don't know all the technical things - but I needed 2 (somewhat) expensive components. Of course they didn't have either onthe truck - so they were able to give me quotes and options. So glad they are not one of those "you need to replace you entire unit" companies I hear so much about
