Old post but thought i would update. Dinosaur said they did not make a replacement board for this unit and yep it's an oddball when trying to reference parts. Remember this a was a new fridge in 2020. The gentleman at Dinosaur did suggest plugging the reefer directly into A/C to rule out a wonky converter supplying choppy DC. Also it has shut off on DC and AC. I took it over to my property back in Dec to do some winterized camping for one night. Sometime the next day while plugged in it tripped off. If it comes down to it I will swap the whole thing out for a Norcold. Any places out there have reasonable prices for a new/rebuilt fridge?
