Re: hotpoint ffa 70
these models suffer from a build up of ice in the duct moulding at rear of freezer. 🙁
firstly check for ice, if it is present get rid with hairdrier.
secondly, replace old fan seal cos these tend to get moist and then freeze up which allows the ice to make contact with the fan and stop it working and also make sure the foam on back of the duct moulding is securely sealed down with foil tape to prevent moisture ingressing and then eventually freezing up.
stats are not replaceable as they are foamed in.
if fault is still present then fit new control module..job done 😀
