Hey, Chad!
The Replacement Main Board Assembly for WFCO Auto-Detect RV Power Centers part # WF66FR will work with an existing WF-8900 converter. As long as everything is the same amperage. The WF-8900 converters is a series of converters so if your converter says WF-8945 that means its a 45 amp.
I've attached a picture of the chart of the different models along with what amperage they are.
If you want, you can reply to the email with a picture of any sort of sticker label with information on it and I can make sure what amperage you have.
