Feature to Know About

A Targeted Fix When the Converter Is the Problem

When a WFCO WF-8955 power center stops charging batteries properly, it's easy to assume the entire panel needs to be replaced. In many cases, the issue is isolated to the converter board itself. This replacement main board lets you restore proper charging and DC power without pulling out the full power center or reworking existing wiring. It's built to current electrical safety standards and supports hi-pot testing, giving added confidence that everything is properly insulated and isolated once installed. The result is a repair that keeps the original enclosure, breakers, and fuse layout in place while restoring safe, reliable charging performance.

Video Transcript for Review of WFCO RV Power Converter - WF76FR

Hi everyone, Steven here with etrailer. Today we're taking a quick look at a main board replacement assembly for the WFCO auto detect RV converter chargers, specifically the 55 amp ones. So folks, this main board assembly will only work with those WFCO WF-8955 power centers, and it uses the auto detect technology to recognize your battery's chemistry and then automatically adjust the charging profile to match. So, you pretty much probably already know that 'cause, again, this is just a replacement circuit board assembly. Of course, you got your fan here, all your wiring, and then of course the main circuitry. And then, of course, it sits on the plastic base.

Now when I measured this insert I got overall, again, we're counting that base here, it's the widest point, I got 9 1/2 wide, 7 1/8 wide this way, front to back, and about four inches tall over all. So again folks, this is a great option for you. This is the replacement main board assembly for the WFCO Auto detect 55 amp RV converted chargers. I'm Steven. Reach out if you have questions about this or any other products, and have a great day.
