  • Millermatic 175 control board issues

    Hello I have a 175 that is doa. I have found that the rv1 i believe it was a trans diode but not sure, was toast. It is a red disc shaped item just above the relays. Does anyone know what the replacement value or part number would be for this item. Mine is vaporized. I bought this at auction so trying to fix so I can solve the rest of its problems.
