I have a Hoover Frost Free Fridge freezer unit HF41d011 which has just Unit stopped working.Lights on mains and door. Replaced sensor on evaporator unit ( Grill to rear of freezer compartment) unit came on freezer OK fridge OK after a few hours, next day all off. Shorted same sensor, tripped FF back into working again, next day, same thing. Is it the control board or a sensor.
