Accidentally plugged into 220v

How long was it until the control boards failed? I'm not sure how long I can keep my claim open for, but it would be nice if it fails sooner than later.

Was it just the control board in the water heater? Did the refrigerator burn out completely? Did you have to replace the refrigerator or have it repaired? What was the cost?

Also, was the refrigerator and water heater already powered on and running when you plugged it into the outlet?

I was told by a previous commenter that if the refrigerator and water heater had not been hot at the time, then it may be okay. But... anything can happen with electricity..

Did you blow your power converter up too or was that not damaged? It was plugged in for about 20 seconds and the converter immediately blew up.

There was no immediate damage as I recall. We heard some clicking noises coming from inside the RV, probably from the converter.

My RV is ancient - 1990. The converter is a B&W 6332. It suffered no damage and still works fine to this day.

I'm not sure the failure of the control boards in the fridge or water heater were related. The fridge was always flaky, I'm not sure if it got flaky before or after we did the 240 V plug in. Sometimes it would kick off on propane, sometimes not. With the water heater, the ignitor would run continuously. I replaced both boards with boards from Dinosaur Electronics and it solved the problem. I don't remember the cost but they were not expensive. The fridge itself nothing was wrong with it.

I do not think either one was on during the over-voltage event.
