I know nothing about the Bel Canto, or Icepower ASC200, so take this advice for what it is. I had the Ice Edge 1200AS2 modules.
Looking at the spec sheet, the ASC200 using 230vac/50Hz @10% THD+N is rated at 290W - so it's close to the suggested 300W.
I would try removing the bad ASC200 module from the case first. If you see no issues doing this, then 'yes' it can be so simple. If you feel there are issues removing it beyond your capabilities, then it isn't so simple.
I would also consider ordering 2 modules at the same time and installing both new modules instead of just replacing the broken module. Use the good/old one as a backup. If you decide to order 2 modules at the same time, remove both modules first to make sure you don't encounter any unknown issues before ordering the modules. Typically, these modules for this type of installation really are very simple plug and play.
