Gfi and possible power inverter problems

I live in Austin and the recent storm caused my Norcold fridge to give me a Ďlo dcí error on my 2013 BW36RV13 that I bought a year ago.
I replaced the battery( old battery was 1 1/2 years) and installed a new power cord.
I unplugged the fridge for several days thinking it might need to reset itself. GFI circuit in bathroom area is working.
Still gives me the error message. Iím thinking now maybe the inverter or maybe there is another gfi circuit Iím unaware of.
Any ideas of where the inverter is located or another gfi? -Thanks

First off Doug, this is a 9 year old thread, several of those folks have moved on, so may want to start a new one.
There's more information we need to accurately answer you're questions.
You stated the fridge is a Norcold which is either LP powered or 120 volts AC from shore cord but needs strong 12 volt DC from your batteries to power up the control circuits. Which means that you have a converter not an inverter.
A converter uses 120 volt AC to provide 12 volt DC to power the lights, furnace fan, exhaust vents, slide pumps/motors & to power fridge & water heater controls.
An inverter uses your 12 volt AC batteries to provide 120 volt AC to usually a residential fridge & possibly a couple plugs.
If your fridge is giving a "lo dc" warning it's due to the batteries, either not charged, weak, need replaced or loose connections.

Thank you for your quick response.
The converter board is fried. There are two spots on the board where a diode or multiple diodes have been burned to a crisp and not replaceable.
The converter is located under the breaker panel and easy to get to.
However, I cannot find anything that looks like it online and has no model # anywhere to tell me what kind it is.
Any suggestions?

( i wish I could send a couple of pics but I don’t think this site lets you post pics )

Hopefully someone else will chime in with the for sure model, but if I recall it's a WFCOXX, sorry don't recall the numbers, but also not sure what the previous owner may have done.
Not sure how or why the converter would fry like that, but hopefully you have a surge protector/EMS (it must be an EMS), either hardwired or portable, connected to the incoming power, if not GET ONE ASAP!
This site does allow posting pictures but there are so many devices using different picture programs that I won't begin to explain how. I use an Android phone to post on here, take pictures & occasionally make a phone call.

You can attach images to your posts - just not embed links to hosted images. Look for the paperclip icon in the reply editor or use the "advanced" editor and scroll down a bit to "manage attachments"

If it was just the DC fuse block you may be able to get a replacement block. You may want to give it some thought with replacing the power supply with a new 4 stage charger , they help with making battery last a little longer . Best converters can help you any any parts or tech support.
