I suspect you can call the parts dept at forest River Berkshire division with your serial number and I’m betting they can tell you what it is and who to call. Make sure it’s the Berkshire division. Numbers are on their website and they’ve been good at helping us out if you’re patient. Mine has a way to reset it on the back and is a Magnadyne. There actually is a small tool that came with ours but a similar device will work. They were super helpful when we had camera issues.
2016 Berkshire XL 40 with 2016 Jeep Wrangler. 380 Cummins.
