Hi Bob. Welcome to the RVForum. You didn't mention what, if any, troubleshooting you've done, so I'll mention some basics. When a string of A/C outlets stops working, the first thing I suspect is a GFI. Have you checked them? The AC unit will certainly have its own circuit breaker, and I'd suggest that you flip it to the off position, then back on. The AC unit runs on 120 volts A/C, but the thermistat that controls it needs 12 volts D/C. Do your 12 volt lights and water pump work? Does your fridge work when you switch it to LP?

Is it a 30 Amp or 50 Amp system?
Hi, thank you so much for the help.
I did check the GFI outlets, they are good and work.
A/C does not work
DC lights do not work, battery is fairly new, but does not seem to be charging.
I have not tried the fridge yet on LP, it does not work on AC
How long do the converters usually last.
thanks again

Based on what you've told us, I'd recommend checking the converter's voltage output. It should be 13+ volts but I suspect you're only going to see low battery voltage - meaning the converter is not working. You can measure its output right at the battery terminals. Make sure the shore-power cord is plugged in before testing. Some converters are better than others and will last longer than others, so it's hard to generalize how long they'll last.

Agree with Kev except I would disconnect one of the battery cables to check the output. If you leave it connected, it could maybe give you a false reading of the output. Disconnect the negative cable/

If you have had the battery cables off recently, check the reverse polarity fuses that a lot of converters have. If they blow you will lose the converter output.
