This Furrion fridge would continuously beep and when the door was opened the interior light would not come on. This to me sounds like a control board that is not sensing the door switch. There is a door switch up on the upper right hand corner of the fridge next to top hinge. I tested the door switch with continuity to verify the switch is opening and closing circuit, it was. All wiring back to control board look good. The control board is faulty and isn’t sensing the door switch. This shows you a control board replacement on that fridge.
