Nothing wrong with a 50amp to 30amp, or even 50amp to 15amp adapter. The adapter should provide power to both legs of the 50amp. It is done all the time.
As far as what converter the OP has, the easiest thing to do is find it, gain access to it, and determine if it is bad using a multimeter, check any fuses/breakers, and get the model number if you need a replacement.
Then call these folks http://www.bestconverter.com/
for an appropriate replacement.
Or skip all the above and call a service tech if you want to go the warranty route.
