I have a Hotpoint Mistral fridge freezer. The fridge seems to be working overtime. The electronic display shows +1 for the fridge but +5 for the freezer, when it normally shows -22 degrees. The freezer compartment is still frozen, but everything is covered in frost. The motor seems to be running permanently, which is not normally the case. Obviously something is wrong but I don't know what part needs replacing.

it sound like the the thermisters are send wrong signals to the pcb, it may be too far frozen for machine to sort its self, i would personnaly defrost the machine or at least 48 hours before you consider checking for faulty parts
