2004 Four Winds Inverter

[rjones1138]

Helping a friend with RV seasonal closing this year and his older 40' Four Winds inverter seems to be going bad. Anyone know either what inverter it uses or any info to help me replace it? Thanks!

It is a trailer, not motorhome. Electrical box is in the entertainment unit in the front driver side of the RV, at the floor, facing you as you enter the trailer. Looks like a WFCO box.

There is no need for the same brand/type inverter(though i suspect you might mean converter)replacement.
But
The name and model of the unseen unit is assuredly painted right on it.
And
If you haven't reset(found) the inverter or converter, how do you know it's bad and not a reset or loose wire or even a breaker?

I'm not sure there's a
Going bad.
How is it going bad?
I have, though I'm pretty sheltered, only known of good/no good on such devices.

there is no inverter in that Power Center. Did you mean a CONVERTER? Completely different animal.

So it seems the trailer has more problems than it is worth to save. I have always had Airstreams that last forever. Also a Thor product. We just went to the Airstream Mothership and saw the museum that Thor Industries built and toured the factory.

But back to the OP, thanks for the attempts at help. I should have been more clear. It is the converter, not an inverter. The symptoms are that sometimes there is no DC power and sometimes it flickers and sometimes it is just fine.

We determined it always comes on at full amperage once it warms up, so I don't think it is loose wires, and no breakers or fuses are bad.

I talked to a former client of mine whose company builds ac to dc power supplies (converters) as well as dc to ac power supplies (inverters) and he said the supply is going bad because of the symptoms.

What I was hoping for is someone who knew something about the model before I had to tear everything apart to get to the label.

Thanks again.

No "tearing apart" needed. After unplugging shore power, remove the few screws holding the front panel on. The converter sits on its own little plastic chassis in the bottom of the box below the fuses.

Disconnect AC side... hot/neutral/ground
Disconnect DC side... Red positive, black negative

Reverse procedure to install new one... an hour at most including lunch.

After my lithium upgrade I no longer need mine... eventually selling cheap on Facebook Marketplace for beer money.
