Just be careful as it is corrosive to metals and I'm not sure the heat transfer plate would do well with sustained contact.
I have used Ozium to restore a CPAP unit obtained from a smoker. It's that good. I will not de-odorize permeable silicon seals which absorb the odor, but the fan, and CPAP seem to respond well. It is commonly used by professional car detailers to give old cars that "new" odor. It works in a way that deoderizers just can't.
Now that you mention that, I hate the "new car odor" smell. And knowing that at higher humidity levels there is condensation that reaches even the nasal mask, I would simply run it with peroxide which will not hurt the silicone or plastic and it would kill the mold on contact. Hopefully AnnieC will get the DME to help her and will update us on how the issue was solved.
