When turned off then on it works. Could not find anything open circuit except for a little black sensor tucked in behind actuater (or flap that restricts air flow to fridge as I call it). When I unplugged the actuater the appliance flashed 5, plugged it in and everything working. Actuater working also (it was turning round and round then stopped in the open position). So anyway does anyone know the fault codes for this and am I on the right track?
