We have a 2019 25j. We were on a trip and smelled “burning” coming from area of inverter. We determined that the fridge has no power now unless plugged in or generator running. I just replaced the batteries, they were very corroded and the battery place said they were bad. but still no power to the fridge. It does not appear that the gfci is tripped, but it appears to be built in to the inverter. Could the inverter have gone bad? The lights and pump still work fine.
