Hello Kevin, thanks for reaching out. It sounds like you are needing to replace an older WFCO converter. I see a few different model numbers here in the question you sent, 8835, 8845 and 8855. Each one indicates a different amperage for the converter so I am not sure exactly which one you are needing. I don't have a way to look that up with the barcode unfortunately.

If you are wanting to replace just the converter I recommend going with a Progressive Dynamics unit. For that I recommend the # PD9245C if you need a 45 amp, or the # PD9260C for 60 amp. If you can let me know which model number is on your converter, I can get back to you and confirm which one will be correct.

Hey Kevin, were you able to confirm which converter model your Wildcat uses? Once you have that, I can make sure the Progressive Dynamics option you pick is the right match. Your update could make it easier for others replacing older WFCO units too.

@JesseM I'm looking for the same converter part that Kevin was. Mine is a 8855. I can't seem to find anything stating a WFCO? This barcode is on the board: 04W04C628060 This is etched in black on the board: 66-B097-1101 Then these are also etched in: 8835 8845 8855; with an X in marker next to 8855. What would be the replacement part to order? Thanks, Dave

@DaveT Hey Dave. I have two options depending on the space you have. The Progressive Dynamics # PD4060K is a bit smaller (10-3/4" L x 7-1/4" H) and has less circuit breaker and fuse ports, but you won't have to worry about it fitting inside the hole for the WF-8855AD. The Progressive Dynamics # PD4560K18LS8 is larger at 10-1/8" L x 13-1/4" T, but it provides more circuit breaker and fuse ports to power you RV's electrical components.

@JesseM Thank you for the reply. Can I not just replace the Converter portion of the unit, and not the whole Power Distribution panel and converter? Thanks, Dave
