If your unit is still under warranty, your dealer can change it for you, a pain to take it in though. The dealer changed mine while I was having other work. You won't necessarily have a problem. The breaker will blow and after two or three seconds come back on. If your breaker is not cutting off, you may not need to change it. Mine was cutting off evertime I moved the slides in or out. Check, you may even have the upgrade already.
