We were camping in Colorado in an “over-capacity” area (the campground had no spaces available but allowed us on the property for a small fee but we were on our own…boondocking on the premises….and they allowed us to use our generator.)
In the middle of the night everything shut-down including the generator. The converter main breaker was “popped”. I reset it, and went out reset the generator, and restarted it. Went inside and turned the AC back on…and everything shut down again.
I thought it was the AC…so I reset everything, left the AC off…restarted the generator…went inside, reset the converter C.B….and everything failed again as the gen shut down again.
Removing the cover to the converter, I discovered overheated components on the main board of the converter.
Next day, called the local RV repair centers and found they did not have our particular converter circuit board in stock…and all gave me a TWO WEEK delivery schedule for a $200 pricetag.

(Most of them wanted me to change my original converter to one of the units they already had in-stock…but that would have required more re-wiring and modification of my Airstream and would not guarantee the replacement unit would fit the exact same space. I decided it would be best to keep the exact same unit rather than attempt such modifications on-the-road.)
I got on Amazon, found the converter board, (WFCO-55A unit), ordered it, selected the Colorado Springs (our next destination) Whole Foods Store Locker…and it arrived overnight for less than $65. Went to the Whole Foods Store, entered the Amazon “code” sent to me in an email…and the locker opened up and THERE WAS MY NEW CONVERTER PART!
Took almost 15 minutes to install…(simple tools, screwdriver and needle nose pliers, plug-and-play connectors)…and that was 5 years ago and it’s still working perfectly!
