During the past 5.5yrs of owning an Adria motorhome from new I have had three failures of this board. The first time occurred within the first year and was replaced under warranty. The second time was two years later in 2022 and I had to replace that one. By that time Thetford had upgraded the board to work with both 3000 series (mine is a 3145) and 4000 series fridges. The problem, apparently, was that the 20A fuse kept cooking and eventually melted and failed. They replaced it with a 25A fuse and uprated circuitry. Well last week I had my third failure and, when the board was replaced Imlooked at the failed unit only to find a cooked 25A fuse. I have written to Thetford as I think this is, not only a design failure but a fire risk. I have attached some pics of the item. It is a bit worrying as it could damage the motorhome, or worse.
