Question:
I have a PD4575K18LS8 power converter system in a Genesis 30GS. I removed the converter section, and it is also marked 4575, but it has dual fans and looks more like the 90 amp converter section. Per your site the PD4575CSV converter is correct, but I wanted to verify before ordering since it looks different.

Hey Bob, thanks for the pictures! Yeah what you have sure does look like the 90 amp part # PD4590CSV but you would want to go by what the numbers say and based on that you have the part # PD4575CSV. Progressive Dynamics has updated the converters several times so it is most likely you have a version that is just slightly different than the current # PD4575CSV.

I had the same concerns but it installed like the old one and has worked well. Dual fans must not have been needed. I did contact the manufacturer and they said it was the correct replacement.
