I have replaced control board in my Dometic refridge and it still doesn't function. I tested for AC voltage on the DC supply and got a wopping 26vac. I assume that is "ripple" voltage and comes from the converter. Is there a workaround in connecting the voltage from the converter to a different source on the converter or do I have to purchase another converter?
I am not an expert on electricity, but 26V AC on a DC circuit doesn't sound right. Why measure the AC volts? What is the DC voltage and where are you measuring it? The output side of the converter or the batteries is my preference for measurement points.

If you open the outside panel, you'll see a terminal block (usually on the bottom left). Check for 12 volts DC.
If you have 12 volts, check if you have heat on either ac (if you are plugged in), or propane. You can check by feeling sheet metal on the right, about a foot above the bottom...be careful, if it's been running awhile it could be very hot.
I measured the ac voltage per a link that went through the test procedure for the board where it said to use a digital meter to do so. I did have 12.3vdc on the terminal you’re saying.
They said that the ac voltage shouldn’t exceed 2.5 volts or something like that.
Thanks for your information.
