The first question I would ask is; do you have a built-in converter or a standalone converter? Usually the answer is "I have no idea, how can I tell"?
It starts with the power center; the black or brown cover with a narrow window in it that houses the fuses and circuit breakers. You need to access that unit to determine what your actual setup is.
On my 2019 Passport with a 30A service, the converter was built into the power center. On my 2024 Cougar with a 50A service, the converter is a separate unit that plugs into the power center with a common power cord.
In this picture from a 2017 Bullet Premier 24RKPR you will see what the power center looks like and quite likely where it is located (same model and year doesn't always mean same location). The size of the one in this picture tells me it is most likely a combined unit. The easy thing to do is remove the two screws in that lower panel and look into the cavity behind there. If you do not see a big silver box screwed to the floor, then you have a built-in converter.
Depending on the brand of the power center, you might be able to replace just the converter component if that is your need/intent to the original question.
