Electrical Problem

Having read your last post, the 50A outlet that you installed now becomes suspect. Check voltages at the newly installed outlet. You should have 240V between the two hots and 120V between each hot and neutral.

Agree with bob. And if you post a pic of the outlet, we can help you determine where you should be measuring from.

I am not an expert on these forums, how do I post pics?

Do you have an account at photobucket/picassa web albums or similar? They allow you to upload pics for free and you get at "forum friendly" link to post here.

Alternatively you can "attach" photos with a post. But since I have a hosting (picassa) place, I'm not sure how the forum attachments work.

If you use "Tapatalk" app to access this forum via your phone, that app also has a attach photo option built-in....

In addition to trying out the suggestions by SAD, if you go to the Forum Technical Support section of the forum, there is a Sticky called "How to Post Pictures on the Forum" (by Hankpage). Look at the very top of the thread list.
If SAD's tips don't work for you, try the suggestions in the sticky.

Here is an excellent source of information about RV electrical supply connections. It covers both 30 amp and 50 amp systems. If you click on the left link titled "OUTLET TESTING" it should guide you through checking your existing house wired 50 amp plug.

Thank you and that was some AMAZING information!! After reading it, I have an idea what the problem may have been. I will have to investigate but I bet it was a problem with the neutral. Anyhow this still has not solved the issue with the AC unit. As I said I did fry the converter and have replaced it and all seems to work as designed, except maybe the ac. Thanks again, I will now pack a volt meter in my camper.

Do you have another thermostat that you can try out? By your post, it sounds as though the thermostat my be doing some odd things. They are easy to change out and will eliminate another potential problem. The thermostat is a low voltage item and may have been damaged.

I was thinking the same, almost as if the thermostat is not telling the ac what to do, but seemed to work fine when on heat mode. When the overvoltage occurred the ac, I think, was the only electrical item running.
